Close the last tab without closing the firefox app

greetings!
1.I would like to close the last tab without closing the app. The behaviour I expect is the app to open a new blank tab when I close the last tab. Currently I cannot close the last tab which already has some website opened in it.
2. When I open a new tab, i'm forced to enter a website address. I expect to the app to simply open a blank new tab & leave it to me whether to enter a address or not.
Thanks for your support. I love firefox for Android.

well, I would prefer to leave it to the end user whether he wants the awesome screen while pressing a new tab button/ or open a simple blank page. Let him choose it in the config.
regards,

How do I "save tabs and quit" in this new version of Firefox, as I did in the older version? I want to be able to see the same websites open from the last time I closed the computer.

In an earlier version of Firefox, when I went to close it, I would get a prompt "save tabs and quit?" that allowed me to see the same websites open from the last time I closed the computer. Where is that feature on the new version of Firefox?

Firefox 4 and later versions save the previous session automatically, so there is no longer need for the dialog asking if you want to save the current session. 
Use "File > Exit" or "Firefox > Exit" (Mac: "Firefox > Quit Firefox") if you want to restore multiple windows or otherwise have problems with restoring tabs. 
You can use "History > Restore Previous Session" to get the previous session at any time. 
You may need to click the orange/gray Firefox button to see History. 
There is also a "Restore Previous Session" button on the default about:home Home page. 
Using the "Show my windows and tabs from last time" setting is a more reliable way to restore session data.

How do I close a numbers document without closing the entire app?

Can anyone tell me how I can close a numbers document without closing the entire app? i.e. go back to the folders display page - is this even possible?

It is not a bug, but a new feature. 
Some menu entries in the main menu bar are hidden if you use the mouse and only appear if you use the keyboard to open the menu (Bug 626825).
You can see the difference if you use Alt+F to open the File menu or other menus like the Edit menu (Alt+E) and Bookmarks menu (Alt+B) and compare that to what you see if you use the mouse to open the menu after you have made the menu bar visible by tapping Alt or by pressing F10.

The last tab, furthest to the right, does not load when restarting FireFox.

Whenever I restart firefox, the last tab I had opened does not load. The matter of restarting can be any kind: new add on installed, new firefox update, restarting the browser manually, or restarting my computer so that firefox is automatically closed. It's always the same problem. The last tab will be displayed as my New Tab page, which is blank. I can have 3 tabs open, and the first 2 will load just fine, but the last doesn't. This means that if I restart for an add-on or something, I need to go back into my history to pull up this last tab, which is inconvenient. And it may not have been my most recent tab. I may open this last tab, go back to an earlier tab and surf the web on that, building my history, and then restart firefox for whatever reason. In those instances, I need to open up the history window and dig for that last tab from memory.

Alright. It appears to be an addon called Load Tabs Progressively. I'll just leave that disabled.

Usually, Firefox closes when closing the last tab on it. Now it doesn't. How do I change it back to closing when the last tab is closed?

I've checked my about:config settings beforehand since I hear the setting for this is usually in there. It's still the same and hasn't been changed. As far as I know, I haven't downloaded any add-ons recently that would cause this change. None have been installed recently. Here's a screenshot of the about:config.

Did you try Safe Mode?
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.
*Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
*Do NOT click the Reset button on the Safe Mode start window

Is it possible to turn off the infrared emitter without closing the sensor

Hi,
The Kinect v1 SDK had a function ForceInfraredEmitterOff(), which could be called to turn off the infrared emitter without having to close the Kinect. This was very useful for applications using multiple Kinects as it provided an easy way of preventing interference.
I am using 3 kinects with overlapping field of views to create a large field of view for a project and I would like to be able to control the infrared emitter like I did with the v1.
I looked in the SDK documentation and on the web, but found no method that could do what I want. So, did I miss something ?
Thanks.

That is exactly what it means: to have a system using two Kinects you will need two computers with two Windows 8 licenses (one each), one communication path between these computers (TCP/IP seems like an obvious choice) and some way to make sure they don't
interfere each other...
As far as Carmine answer goes, it is not satisfactory: OK, I understand that my Kinect is shared by all the applications running on my computer .... MY computer, meaning that I know which applications need the sensor and which ones don't (unless some unknown
background program is spying on me.... wouldn't want to shut off the IR to prevent that program from working now...)
So, why not give programmers a way to shut off the IR and if someone runs many programs on the same computer and does not want to shut off the IR then they just don't call that function ... this way everyone is happy.
SO, in the end here is the solution my company decided to implement: we used to put 3 kinects on each of our system to have a very wide field of view. This year we plan on selling about 75 of these systems, that would have meant buying 225 Kinects. Now,
since we can't turn off the IR (a functionality that would take any programmer about 10 minutes to implement by the way), we will buy only 75 Kinects (one per system) and mount them on a linear axis. It is acutally going to cost less money to buy one linear
axis and move the camera instead of buying 3 cameras with 3 computers with 3 windows licenses and developping some sort of anti-interference solution.

Is there a way to close a pinned tab without unpinning it or closing the browser completely?

when i have one of my pinned tabs opened and i open a new tab, i cant find a way to close the pinned tab without closing the browser completly.
is there a way to close a pinned tab?
thanks.

You can also middle-click a tab to close that tab and that also works for pinned tabs.

When I close the last tab I am sent to my desk top and do not stay on Firefox, but if I hit the open button again it says Firefox is running??

This started this last weekend. When I close the last tab instead of staying on Firefox it goes directly to my desktop. If I hit the Firefox icon again I get a message saying that Firefox is still running and that I should restart. But if I just hit open again it reopens or shows Firefox home page again. How do I stop this?

Set the pref browser.tabs.closeWindowWithLastTab to false on the about:config page to prevent closing the last tab from closing that window, you need to use "File > Close Window" or the close X on the title bar.
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page. 
*Use the Filter bar at to top of the about:config page to locate a preference more easily.
*Preferences that have been modified show as bold(user set).
*Preferences can be reset to the default or changed via the right-click context menu.
You may need to wait a bit longer before restarting Firefox.

How to close locked tab without closing firefox

When firefox freezes how do I close offending tab without closing firefox

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 (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.
*https://support.mozilla.org/kb/Safe+Mode
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
If it works in Safe Mode and in normal mode with all extensions (Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)
*If you have many extensions then first enable half of the extensions to test which half has the problem.
*Continue to divide the bad half that still has the issue until you find which one is causing it.

How do I selectivly close the only not responding window (without closing the other 3 responding windows)

Presently, I have 4 windows opened, each with a bunch of tabs.
Since I restarted firefox this morning, one out these 4 windows, keeps on not displaying.
How do I selectivly close this only window (without closing the 3 others windows)

Here is what the manpage shows:
[ps(1)|http://developer.apple.com/documentation/Darwin/Reference/ManPages/man1/p s.1.html]
state The state is given by a sequence of letters, for example, ``RWNA''. The first letter indicates the run
state of the process:
I Marks a process that is idle (sleeping for longer than about 20 seconds).
R Marks a runnable process.
S Marks a process that is sleeping for less than about 20 seconds.
T Marks a stopped process.
U Marks a process in uninterruptible wait.
Z Marks a dead process (a ``zombie'').
Additional characters after these, if any, indicate additional state information:
+ The process is in the foreground process group of its control terminal.
< The process has raised CPU scheduling priority.
<div class="jive-quote"> The process has specified a soft limit on memory requirements and is currently exceeding that
limit; such a process is (necessarily) not swapped.
A the process has asked for random page replacement (VA_ANOM, from vadvise(2), for example,
lisp(1) in a garbage collect).
E The process is trying to exit.
L The process has pages locked in core (for example, for raw I/O).
N The process has reduced CPU scheduling priority (see setpriority(2)).
S The process has asked for FIFO page replacement (VA_SEQL, from vadvise(2), for example, a large
image processing program using virtual memory to sequentially address voluminous data).
s The process is a session leader.
V The process is suspended during a vfork.
W The process is swapped out.
X The process is being traced or debugged.

In the latest version of Firefox, I am not able to open a new tab neither by Ctrl+T nor from the File Tab nor by pressing the '+' sign next to the last tab

In the latest version of Firefox, I am not able to open a new tab neither by Ctrl+T nor from the File Tab nor by pressing the '+' sign next to the last tab. So the only solution is opening "New window" which is extremely messy. Kindly help me with this issue.

hello, can you try to replicate this behaviour when you launch firefox in safe mode once? if not, maybe an addon is interfering here...

In CVI !!!! How to dynamic change BaudRate of RS232 Serial COM Without closing the Port !!!

Dear all:
I want to change the buadrate of serial com without closing the serial com, but it failed when I use the function "SetCommConfig(m_hCom, &Com_cfg, Com_cfg_S) " to reset the buadrate ,baudrate is no change when use GetCommConfig to read back the value.
Appreciated all of your advice . TKS!
Code with WINAPI as beloow:
CreateFile(..) ;
GetCommState(..);
dcb.BaudRate= 1000000 ;
SetCommState(..);
//......do other things
//change baudrate to normal without closing port .
GetCommConfig(m_hCom, &Com_cfg, &Com_cfg_S);
Com_cfg.wVersion = 0X100;
Com_cfg.dwProviderSubType = 1;
Com_cfg.dcb.BaudRate =9600 ;
Com_cfg.dcb.StopBits =1 ;
SetCommConfig(m_hCom, &Com_cfg, Com_cfg_S);
GetCommConfig(m_hCom, &Com_cfg, &Com_cfg_S);
Solved!
Go to Solution.

This topic has been discussed some years ago: see here. Please note that even if I made that sample program which changes the baud rate without closing the port, I never used it in a real situation: you'll need to made your tests and check if this solution can satisfy your needs in the short and long term.

Unable to close home page tab or unable to close firefox by closing home page tab (when if that is the only last tab remaining in the browser

Recently I noticed that I could not close my browser by closing the last tab, which is nothing but home page tab. also noticed that when I open my browser and after opening many other tab if I want to close home page tab I could not close. If I closed it then I cant navigate or surf from that tab.
This may be due to some add-on causing trouble.
The problem does not arise in safe mode. Also if I group tab after closing, it is counted as tab but I cant open that particular tab.

Firefox closes when I close the last tab, on one system not the other

Ctrl-W closes the last tab. On my Windows XP machine I get an empty window Good. This is like Windows and Excel, you can close all pages without quitting the application.
On my Windows XP Professional system it Exits Firefox. Not good. I don't want it to close until I hit Alt-F4.
== This happened ==
Every time Firefox opened

1. Read about [http://kb.mozillazine.org/About:config about:config]
2. Change preference
browser.tabs.closeWindowWithLastTab
to false.
Does it help you?

Closing the last tab.

I would like to be able to close the last tab and also to close all tabs.
There two reasons I want to do this:
1. I am finished with the tab, and I want it to go away so it won't distract me.
2. There is something on the tab I don't want other people to see. I want it to go away rapidly without having to shut down Firefox entirely along with that delay.
Every other program I use lets me close the last tab.

The Last Tab Close Button add-on will add a close tab button to the last tab - https://addons.mozilla.org/firefox/addon/last-tab-close-button/
The Close All Tabs (Reloaded) add-on gives you the option to add a toolbar button to close all tabs - https://addons.mozilla.org/firefox/addon/close-all-tabs-reloaded/
