Firefox can't find my printer under linux

Even though it is shown in about:config firefox shows no printer when I want to print something.
This has been a problem for some time. Why don't you guys concentrate on getting Firefox right rather than adding more useless crap. I would just like to be able to print, I don't need the other crap. Why write 10,000 lines of code to automatically find a printer when people can open up the preferences and just type in their printer. I realize most Firefox users are dumb asses, but surely they know which printer they have. This is Microsoft windows thinking, where you believe the software has to do everything and the user just has to sit there with a blank stare while the computer decides for them everything they need.

Firefox simply ain't a usable browser under linux anymore, try chrome or something
else but firefox has become a disaster. SLow, no print support , every other week a new version with unwanted new buggy features without ever fixing the bugs in existing versions and keeping the existing bugs in new versions alive.

Can't find network printer

I've got a HP Photosmart Plus installed on my network. I install it on every computer in the house (4 computers), and then it works.
But when I close the computer and restart, the computer can't find the printer.
It's still connected to the network, that I can see if I open my router.
The only way is to reinstall the printer, but sometimes the computer can't find the printer to install.
This happens on both W7 oand W8.
Anyone knows whats wrong.

These settings are for setting up your wireless printer to stay connected to your router, keep wireless devices better connected and makes your router secure and hack proof.
1. Set a static IP in the printer (click here) outside the DHCP range of the router (check your manual).
   This is for Linksys routers but can be used for all routers. Verify your DHCP range and change this
   first if needed. More Wireless Printing help is here (Windows solution 4, static IP).
2. Verify in the printer that 'Auto Off/Sleep' is disabled. Use the Embedded Web Server (EWS) by going
   to the printers IP address in your browsers address bar, click Settings Tab/Auto Off. Or use the Printer
   Assistant, Printer Home Page (EWS). Also check your Printers Properties.
3. If the printer supports and has IPv6 enabled, turn off IPv6 in the printer.
4. If needed and you assigned a static IP address, try using 8.8.8.8 for the Preferred DNS server and
     8.8.4.4 at the Alternate DNS server.
In the router: (Refer to your router manual for information)
5. Use a fixed wireless channel like 1, 6 or 11, never 'auto', try channel 1 first then the rest.
6. Set router to 20Mhz only, or 145Mbps depending on router.
7. Always use WPA2-AES (Personal) encryption, but you can try ‘mixed’ mode.
8. Disable WPS and never use it and disable UPnP for the routers security. Nobody can hack your
   system now and helps with wireless connectivity (if you want to know why, search the web).
9. If you have a dual band router (2.4Ghz and 5.0Ghz bands), make sure the SSID’s are NOT the same,
   they must be different for all bands, even for any Guest networks.
10. SSID broadcast must be enabled.
11. Save all settings. Power off both, wait 2 mins. Power on router wait 2 mins.
12. Power on printer and verify it reconnects to router.

Apart from being able to execute an ABAP program in the Debugger, you can also start the Debugger call by the choosing a breakpoint. This is achieved by setting one or more of these breakpoints in the program. A breakpoint is a signal at a particular point in the program that tells the ABAP runtime processor to interrupt processing and start the Debugger. The Debugger is activated when the program reaches this point.
There is also a special kind of breakpoint called a watchpoint. When you use watchpoints, the Debugger is not activated until the contents of a particular field change. For more information, refer to the chapter Watchpoints.
Breakpoint Variants
The Debugger contains different breakpoint variants:
Static
A user-specific breakpoint is inserted in the source code as an ABAP statement using the keyword BREAK-POINT. A non user-specific breakpoint is set in the ABAP Editor using the BREAK user name statement.
Directly set
dynamic breakpoints
Can be set in the ABAP Editor or the Debugger by double-clicking a line, for example. Dynamic breakpoints are always user-specific, and are deleted when you log off from the R/3 System.
Breakpoints
at statements
The Debugger stops the program immediately before the specified statement is executed.
Breakpoints
at subroutines
The Debugger stops the program immediately before the specified subroutine is called.
Breakpoints at function modules
The Debugger stops the program immediately before the specified function module is called.
Breakpoints at methods
The Debugger stops the program immediately before the specified method is called.
Breakpoints at exceptions and system exceptions
The Debugger stops the program immediately after a system exception, that is, after a runtime error has been intercepted.
Static Breakpoints
Static breakpoints are always user-independent if there is no specification of a user name. Once a user has inserted the statement BREAK-POINT or BREAK name in an ABAP program, the system always interrupts the program at that point for that user or only for the user name. This procedure is only useful in the development phase of an application when program execution is always to be interrupted at the same place. For more information, refer to the chapter Static Breakpoints.
In HTTP sessions, a static breakpoint is skipped if you did not set additional dynamic HTTP breakpoints in the editor of a BSP page. Instead, a corresponding system log entry is written, which can be checked using transaction SM21.
Dynamic Breakpoints
Dynamic breakpoints are user-specific. Therefore, you should use them if you only want the program to be interrupted when you run it yourself, not when it is being executed by other users. All dynamic breakpoints are deleted when you log off from the R/3 System.
Dynamic breakpoints are more flexible than static breakpoints because you can deactivate or delete them at runtime. They have the following advantages:
·        You do not have to change the program code.
·        You can set them even when the program is locked by another programmer.
·        You can define a counter that only activates the breakpoint after it has been reached.
Special dynamic breakpoints are useful when you want to interrupt a program directly before a particular ABAP statement, a subroutine, or an event, but do not know exactly where to find it in the source code. Event here is used to refer to the occurrence of a particular statement, for example, or calling up a method. Special dynamic breakpoints are user-specific. You can only set them in the Debugger. For more information, refer to the chapter Dynamic Breakpoints.
In HTTP sessions, the system stops both at static and dynamic breakpoints if a dynamic breakpoint was set in the editor of a BSP page before program execution.
Lifetime and Transfer of Breakpoints
A static breakpoint remains intact as long as the BREAK-POINT or BREAK-POINT name statement is not removed from the source code. Without saving, dynamic breakpoints only remain intact in the relevant internal session. However, they remain in effect during the entire user session if they are saved by choosing the menu path Breakpoints ® Save in the ABAP Debugger. For more details on the subject of user sessions and modes, refer to Modularization Techniques in the ABAP keyword documentation.
If you call an HTTP session during a user session, only the HTTP breakpoints are loaded when the HTTP session is started. You activate HTTP debugging in the ABAP Editor by choosing Utilities ® Settings ® HTTP Debugging. Depending on the setting, the system then displays either the HTTP or standard breakpoints in the Editor.
If you call an update session during a user session, breakpoints that were defined beforehand in the calling processing unit are copied to the new update session, where they can be displayed under Breakpoints. If, in the ABAP Debugger, you check Update Debugging under Settings and then, for example, call the update module func using CALL FUNCTION func IN UPDATE TASK, a new window is opened in which you can debug this function module in the update session. All the breakpoints that were set in the calling processing unit can also be processed here.
For further information on special breakpoints, refer to:
Breakpoints at Statements
Breakpoints at Subroutines
Breakpoints at Function Module Calls
Breakpoints at Methods
Breakpoints at System Exceptions

WINDOW TYPES
When defining a layout set window, you must select a window type for the window. You can choose between three types:
Constant windows (CONST)
Variable windows (VAR)
Main windows (MAIN)
CONSTANT WINDOW
A window of type CONST has the same contents and size on all layout set pages, on which a corresponding page window is defined. This allows the processing of the window contents to be optimized internally.
Page windows whose allocated window is of type CONST must have the same size throughout the layout set. If a window of type CONST is full, all remaining text the application program wants to output in this window, is lost. Constant windows do not trigger a page break. In other words: all text exceeding the window size is simply truncated.
VARIABLE WINDOW
The contents of variable windows is processed again for each page, on which the window appears. The system outputs only as much text as fits into the window. Text exceeding the window size is truncated; the system does not trigger a page break. Unlike constant windows, the page windows declared as variable windows may have different sizes on different layout set pages.
As far as the processing of the window contents is concerned, the system currently treats constant and variable windows alike. The only difference is that constant windows have the same size throughout the layout set.
MAIN WINDOW
Each layout set must have one window of type MAIN. Such a window is called the main window of the layout set. For SAPscript layout sets, the main window has a central meaning:
It controls the page break.
It contains the text body that may cover several pages.
It allows to fix text elements at the upper and lower margins of the allocated page window (for example, for column headings).
As soon as a window of type MAIN is full, SAPscript automatically triggers a page break and continues to output the remaining text in the main window of the subsequent page. Page windows of type MAIN have the same width throughout the layout set. The SAPscript composer thus avoids reformatting of the text after each page break.
If a page does not have a main window, the system implicitly processes all other windows of the page and continues with the subsequent page. This page must not call itself as subsequent page (recursive call), since this would produce an endless loop. In such a case, SAPscript terminates the output after three subsequent pages.
HOW THE COMPOSER WORKS
The composer or layout set processor is the central formatting module for the print output. It prepares the texts for the different output devices by using the allocated styles or layout sets.
Processing a layout set happens in a certain order. You must know some facts concerning the different window types, the setting of subsequent pages, or the dynamic control from within the print program.
Page control in layout sets
Define subsequent page statically
Define subsequent page dynamically
Format a layout set page
PAGE CONTROL IN LAYOUT SETS
SAPscript automatically triggers a page break as soon as the main window of one page is full. To be able to execute the page break, the system must know on which subsequent page to continue outputting the text. You can specify the subsequent page either statically when defining the layout set, or you can set the subsequent page dynamically during layout set output.
If the subsequent page is not specified, SAPscript automatically terminates printing, thereby ignoring any other output statements of the application program.
DEFINE SUBSEQUENT PAGE STATICALLY
You define the subsequent page statically with the layout set maintenance transaction. First, specify the start page in the layout set header. The system automatically calls this page whenever the layout set is started. With this page, or, more correctly, with the page window of this page, the text output starts. For each page, specify the subsequent page in the page definition. After a page break, the system continues text output on the subsequent page defined for the last page. By specifying start page and subsequent pages, you can define a page sequence.
DEFINE SUBSEQUENT PAGE DYNAMICALLY
The page sequence set in the layout set definition can be changed by the application program dynamically at runtime. If you want the layout set to start with a page other than the one defined in the layout set header, specify the desired start page using the parameter STARTPAGE when you call the function module START_FORM. However, this new start page is valid only for the current call of the function module.
If you want to break to a subsequent page other than the one specified in the page definition, use the control statement NEW-PAGE to set the name of the new page.
NEW-PAGE .
NEW-PAGE ends the output on the current page. The new subsequent page is only valid for the current call of the control statement. You can either include the control statement explicitly into the text of a text element or pass it to the layout set output using the function module CONTROL_FORM.
FORMAT LAYOUT SET PAGE
The process of formatting the output is controlled by the text contents in the BODY area of the main window. If the main window is completely filled, or if the control statement NEW-PAGE appears in the main window, the system executes a page break. Only at this point in time the system formats the contents of the windows of the other types and replaces the variables with the current values.
For each other window, the system first outputs the default text element, if it exists. Then it processes and formats the list of the active text elements of this window, which you set using the function module WRITE_FORM with the parameter FUNCTION (SET, APPEND, DELETE). Any text that does not fit into the page window is truncated.
As a consequence to this processing order of the composer, the reservation of space for the TOP and BOTTOM areas must be made beforehand. If the BODY area of the main window already contains text, a new text output to the TOP area does not appear on the current page but on the subsequent page in the TOP area. The same applies for the BOTTOM area. If the BODY area is filled to such an extend that the new BOTTOM text no longer fits into the current main window, this text appears on the subsequent page in the BOTTOM area.
A frequent error in application programs is that for the subsequent page (for example, NEXT) of a layout set no main window is defined. If the formatted text of the previous page did not fit into the corresponding main window , the composer searches the subsequent pages for a main window to output the text remainder. However, if the subsequent page of NEXT is NEXT again, the composer encounters an endless loop.
To be able to create correct page breaks in longer text, you should define a main window on each layout set page.
LAYOUT SET CONTROL
To output SAPscript layout sets, in the print program you must always start the output with OPEN_FORM and end it with CLOSE_FORM. The function module OPEN_FORM initializes the SAPscript composer and opens the specified layout set for subsequent output. The system combines all output for this layout set up to the CLOSE_FORM to one print request. If CLOSE_FORM is missing, nothing will be printed.
To output data in a layout set, you must use the SAPscript function modules WRITE_FORM, WRITE_FORM_LINES, and CONTROL_FORM. You can use these function modules any number of times in any order between opening and closing a layout set.
You cannot use the ABAP/4 statement WRITE to write output to a SAPscript layout set.
Several print requests
Start a layout set again
Switch layout sets
Find layout sets
SEVERAL PRINT REQUESTS
Within one transaction, you can open and close several layout sets using OPEN_FORM and CLOSE_FORM, however not simultaneously. You can use parameters in the OPEN_FORM to control whether the output is stored in the same print request. But also the SAP spool decides, depending on several plausibility checks, whether new output is appended to an existing print request or whether to create a new print request anyway.
CALL FUNCTION 'OPEN_FORM'
CALL FUNCTION 'CLOSE_FORM'
CALL FUNCTION 'OPEN_FORM'
CALL FUNCTION 'CLOSE_FORM'
You cannot combine ABAP/4 list output and SAPscript output in one print request.
START A LAYOUT SET AGAIN
Usually a print program does not print only one urging letter or one account statement, but several layout sets for different customers. To have the output for each customer begin with the start page of the layout set, you must start the current layout set again and again.
To start a layout set again, you must first end the current layout set and then open the layout set again. Within one print request, first call the function module END_FORM. It executes the final processing for the current layout set. Then start the layout set again using START_FORM. Output then begins again on the start page of the desired layout set.
CALL FUNCTION 'OPEN_FORM'
CALL FUNCTION 'START_FORM'
CALL FUNCTION 'END_FORM'
CALL FUNCTION 'START_FORM'
CALL FUNCTION 'END_FORM'
CALL FUNCTION CLOSE_FORM
If you use START_FORM and END_FORM, you must not specify a layout set for OPEN_FORM. However, in this case you can use the SAPscript output functions only after opening a layout set with START_FORM.

Since upgrading to Firefox 27.0 some webpages will not load when I click on them. It gives me a message saying that Firefox can't find the server.

Since upgrading to Firefox 27.0 some webpages will not load when I click on them. It gives me a message saying that Firefox can't find the server. I have to click the link several time before it will load and sometimes when they do load it does not show the page right. It is like the HTML is messed up or something. I have tried everything I can think of. I started in safe mode, still did it., I removed add-ons, still did it., I reset Firefox and still did it., I completely uninstalled Firefox and re-installed Firefox and it still does it. I have tried Malware Bytes Anti-Malware scans and Avast boot-time scans and found no malware or viruses. I have found that those websites open the first time with no problems on my IE9 and they used to do so in Firefox 26.0. I'm at my wit's end. The website links are in my bookmarks and are used all the time so they are trusted and my avast is set to allow them. They range from news websites to gun websites and everything I have read says that Mozilla does not filter those unless something has changed recently.

Try this as a first step; 
Clear the Cache '''''Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"''''' 
and 
Remove Cookies '''''Firefox/Tools > Options > Privacy > Cookies: "Show Cookies"''''' 
If there is still a problem,
'''''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]'''''
While you are in safe mode;
'''''Firefox Options > Advanced > General'''''. Look for and turn off '''Use Hardware Acceleration'''.

Firefox can't find the file at (a location is specified) when either "Navigate previous" (and next) buttons are pressed in an HTML5 skin (but OK in IE/Chrome).

I create HTML5 help projects from a package called MadCap Flare. It uses what they call an HTML5 'skin' that sets the style/layout of the page and also includes 'Navigate previous' and 'Navigate next' buttons. When viewing the help and pressing these navigate buttons in IE8 or Chrome 32 there is no problem, but in Firefox 27 I get the following: (typical error for pressing a button on any page)
"File not found"
"Firefox can't find the file at /C:/SVN/FlareEnglishOnLineHelp/Output/HTML5_Help_Modeller_Reference/4attrib/idh_jointinterface_element_meshes.htm?TocPath=Modeller Reference Manual|Chapter 5 : Model Attributes|Meshing|_____2."
" Check the file name for capitalisation or other typing errors."
" Check to see if the file was moved, renamed or deleted."
- Because the files and buttons work in other browsers I'm wondering just what is going on here with Firefox>>>>

I should correct that last entry and state that the | charactacters are generated automatically in the Toc-Path for each 'book' name in the online help, and are not something manually created, whereas the : characters have come from the TOC book topic names (which were manually entered names and are what we would ideally require). But, because 'previous' and 'next' topics within nested TOC books without colon (:) characters CAN be browsed successfully when just | characters are present in the Toc-Path, the limitation would appear to be solely due to the : characters.

My home page is google and it works but when I open a new tab it displays an error message :Firefox can't find the file at chrome://quick_start/content/index.ht

I've made sure a dozen times that my home page is set correctly, and when I hit the home button next to the search bar it works and takes me right to google BUT whenever i open a new tab i get the error that my page cannot load and the web url that it keeps trying to remember is in the error message:
Firefox can't find the file at chrome://quick_start/content/index.html.
of course the last dot is not the url anymore but the end of the sentence for the error message, but i don't ever use chrome ever on my laptop only my cell so what is going on????? help fix god please!!!!!!

Do you have the FastStart extension?
Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

*Do NOT click the Reset button on the Safe Mode start window

Can't find wireless printer with E2000 router

I have a Dell Inspiron 1720 (running Vista Home Premium) that connects to my Linksys E2000 and to a wireless printer, the Canon MX870. It's been working for months without problems.
I just got a Toshiba Satellite P770-BT4G22 Laptop (running Window 7 Professional 64 bit) and installed the Cisco Connect software following the instructions where you have already set up the router and just need to install the software to do things like add a device. I can connect to the router fine using a web browser or the Cisco Connect Software and my Toshiba connects to the Internet through the router without problems.
The problem is Cisco Connect says it can't find a wireless printer when I run it on my new Toshiba. I've put the printer within 3 feet of the router with my Toshiba in between but still it can't find it. My Dell in another room connects to the printer no problem. And I can print to the Canon if I select the Shared Canon Printer ( on the Dell) using the Toshiba's Control Panel Add Printer function. But obviously that means the Dell has to be on so that's not good for much more than troubleshooting. I've also wired a connection from the printer to the Toshiba and downloaded the latest driver, printed that way so I know that's not the problem. The problem is that Cisco Connect can't find the printer. It says there are 6 devices attached to my router so it's seeing something, but I guess not the printer. I've turned any firewalls off for this testing too.
I'm stumped as to why it can't find the printer when the Dell did and they are all on the same network. Unless it's not compatible with 64 bit Windows. Any help would be greatly appreciated.
Thank you.
Solved!

I have already added the printer to my network using Windows Add Printer prior to assigning the printer a static IP. But I followed your instructions in making the IP static so if I reset the router I don't have to go through the process again.
When I ran CC and told it to add a printer, it did not identify any printer for me, it went from the screen where you say to add a printer to one where it asked me to name the printer. Honestly, I wasn't even sure if it was referring to the Canon because I'd already added it using Windows, albeit without a static IP, just by knowing what IP it had been assigned. After I gave it the name, it went back to the "home" screen with computers & devices, parental controls, etc. No errors, but no real way to see or change what I had done.
That's why I was asking if there's a way to look at the router and view devices that have a static IP. I can view the DHCP table but it's not there of course. I don't really see anywhere using the router software (either by web connection or CC) where the Canon printer is listed. I see it in Windows Printers, but I saw it there before I reran CC and it asked me to name it.
I appreciate your help and I'm glad to be up and running with it. Especially with having a static IP. I'm just trying to better understand what happened and how to view my devices connected to the router.
Thank you very much for your help.

You would need to get the IP address of your printer then manually add a network print queue.
To get the IP address, on the control panel of your printer, press on Setup > Network Setup > TCP/IP > View/Set IP address.

Strange message: "Firefox can't find the file at /b" Please advise.

When I open Firefox I get this message: “Firefox can't find the file at /b". As a browser Firefox is working for me but I have to click the google search button to connect to the internet. I have tried everything I can think of including uninstalling, reinstalling and updating firefox but to no avail. Please advise. Thank you!!

Try the Firefox SafeMode to see how it works there. 
''A troubleshooting mode, which disables most Add-ons.'' 
''(If you're not using it, switch to the Default Theme.)''
* You can open the Firefox 4/5/6/7 SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. 
''Don't select anything right now, just use "Continue in SafeMode."''
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one.

Since installing lion my iMac and powebook can't find my printer

since installing lion my iMac and macbook pro can't find my printer (it is on the supported devices list and I downloaded the latest drivers).
I called canon and they stepped me through reseting my print system and reinstalling the print drivers and libraries but I have tried direct USB and via airport and the computers dont recognise the printer anymore. Just to be sure it was not the printer I tried to print from my iphone and that works...
I have changed the usb cable, changed usb ports and nothing can get the computers to recognise the device. Please help all advice welcome!

:-) here's an interesting link http://support.apple.com/kb/HT3669#canon
Note: If you've haven't used Software Update recently on your Mac, please run it before connecting a printer or scanner to update your Mac's database on what software is available.
I would also do this after you plug in your printer. Apple might have updates for your printer.
there is Canon Software for lion. try uninstalling everything and starting from 0.
http://www.usa.canon.com/cusa/consumer/products/printers_multifunction/office_al l_in_one_inkjet_printers/pixma_mx860#DriversAndSoftware
I also read that if your printer shows up in your printer list before the appropriate drivers are installed, it might mess things up, if you plug in your printer and see it after cleaning everything you had done previously off, then try removing it from the printer list (don't just unplug it, delete the profile). And then install the appropriate drivers.

Tried to print from ipad4 with wifi printer. Saying can't find air printer. Printer on and it has printed previously.

Tried to print from my ipad 4 but saying can't find air printer. It has printed before.

Sharonanthony-
First, try double-clicking your Home button. A row of recent Apps will line up along the bottom of the screen. Scroll across and look for the Print Center icon. If it is there, you should be able to delete any print job that might be hanging it up.
If you can access the internet, then you should have a good connection to a printer that is using the same WiFi. If you do not have your normal connection to the internet, then I suggest you unplug your WiFi router for a few seconds. Then reset the iPad's network at Settings-General-Reset-Reset Network Settings. You will need to reconnect the iPad to WiFi.
