I can't find the "start up" option in the tools - options - general tab.

I have lost the "restore previous session" action from Firefox at start up.
Looked in Tools - Options - General and there is no option to change behavior at start up.

Delete the file 'com.apple.KeyboardViewerServer.plist' in

I want to have all my tabs return after closing. In Tools/Options/General/ I have' Show my Windows and Tabs from last time' checked, but it does not work. When I open FF again none of my formerly open Tabs show... FF v.4.

Make sure that you do not use [[Clear Recent History]] to clear the "Browsing History" if Firefox is closed.

Firefox loads a blank page instead of homepage despite correct tools/options/general settings (win 7)

I am running namoroka and firefox both in win 7. I have set the tools/options/general (or main) tab setting to specify my homepage and to load my homepage when the browsers start. Nevertheless they both open blank pages when I hit the plus button to open a new browser page

If you want the home page to open in a new tab then you can middle-click or hold down Ctrl and left-click the toolbar Home button.
You can look at one of these extensions:
* NewTabURL : https://addons.mozilla.org/firefox/addon/2221
* New Tab Homepage : https://addons.mozilla.org/firefox/addon/777

Firefox options general tab not working

When I go to Tools > Options, all of the tabs are working except for the General tab, which, if I try to switch to it, just keeps on showing whatever was in the last tab I was in rather than showing the stuff that should be in the General tab. Some kind of spyware toolbar got installed on my computer the other day, so I would guess that either the malware did something to cause the problem, or I accidentally changed something that shouldn't be changed while trying to remove it. Any suggestions on how to fix this? Thanks.

Try to start Firefox in [[Safe mode|Safe mode]]. This mode disables all extensions, user customizations, hardware acceleration, etc. temporarily for diagnostic and troubleshooting. If Firefox works fine in Safe Mode, then this is likely an add-on issue. Restart Firefox in normal mode, then type "About:addons" (without the quotes) in the address bar. Disable your extensions one by one, restarting Firefox between each one, until you find the trouble maker. Once you do, you can disable that add-on and report the issue to that add-on's developer.
A few other basic trouble shooting things you can try is this:
Run all Windows Updates, install all needed service packs, etc.
Update your graphics driver (Firefox uses your graphics card for some rendering, and an out of date graphics card driver can cause problems. [https://support.mozilla.org/en-US/kb/how-do-i-upgrade-my-graphics-drivers https://support.mozilla.org/en-US/kb/how-do-i-upgrade-my-graphics-drivers].
Update all your plugins (Flash, Java, etc.): [http://www.mozilla.org/plugincheck/ http://www.mozilla.org/plugincheck/].
Download and Install MalwareBytes Anti-Malware, run a full Scan. [http://www.malwarebytes.org/ http://www.malwarebytes.org/]. This helps check that there are no viruses on your computer causing issues. You can uninstall this program after you clean off any infections.

I Hate Bing and when I click on a Firefox NEW Tab and search I keep getting Bing results, I used to get Google which I would like back, my homepage when opening Firefox is not Bing but all tab searches retrieve Bing results.

My homepage when opening Firefox is not Bing, yet for some reason today it started using Bing instead of Google for my NEW tab search results. I already deleted Bing from the search bar, no results. Deleted Bing from my computer's control panel. I just want to be able to click a new tab and have my results in google as I always have.

hello, you have a malicious addon present on your pc. <br>please go to ''firefox > addons > extensions'' & remove ''LyricsParty''.
also go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there and run a full scan of your system with the security software that you have in place and different other tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] & [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner].

Not responding when opening FireFox 4.0b7

Hi there,
When opening FireFox 4.0b7 the browser hangs for about a minute and I get (Not Responding). If I use FireFox 3.6.13 I have no problems at all or if I use any of the other browsers, link IE9 Beta. What is going on?
The opening webpage we use is: www.tlc-online.co.uk/ I have changed the opening homepage to www.bbc.co.uk/ and the same thing happens.
Thanks for reading and any help you can give.

This will most likely due to hardware acceleration. There are a number of bug reports that are still being worked on to improve startup times with hardware acceleration turned on.
You can turn off hardware acceleration to improve startup times. To do that in the Tools menu select Options to open the options dialog. Select the Advanced panel, and then the General tab. Uncheck the setting "Use hardware acceleration when available".

When opening Firefox, it opens 4 separate FF programs with a blank page on each program.

I have my Firefox home page set up as Yahoo! Mail, but when I first open Firefox I receive 4 separate Firefox sessions with a blank page for each session. When I click on Tools/Options, it says Yahoo! Mail is still my home page.

It is possible that there is problem with the files [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]
Delete [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]

If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
You will have to redo App Tabs and Tab Groups after deleting sessionstore.js.

Avast detects URL:MAL when opening firefox.No issue with IE or Chrome,after troubleshooting realized problem is NoScript addon.Can it have been infected?

avast -network shield
Infection Details
URL: http://188.24.140.190/
Process: C:\Program Files (x86)\Mozilla Firefox\firefox.exe
Infection: URL:Mal

Hi Tyler,
Thanks for quick reply
Initially after some troubleshooting I noticed that I could make infection pop up disappear:
From Configure how firefox connects to the internet -> changed from "use system proxy settings" to "auto-detect proxy settings" or "no proxy"
With this option modified, the pop up from avast didn't appear any longer when opening Firefox.
However I noticed that both Chrome and IE were set to work on the same "use system proxy settings" and they weren't causing problems...so I assumed the problem still has to be with firefox.
After changing back the option in firefox to "use system proxy" I got again the notice, but saw that when opening firefox in safe mode the issue was gone again.
I tracked it to the no script addon, after removing it, the issue disappear regardless of proxy config settings...when I reinstall it, it appears again.
I am now running in depth virus scans to see were the actual infection is.
It seems to me it is expoiting a vulnerability in this addon, I will try the reset also.

When opening Firefox 6 I receive 2 JavaScript Application errors; the 1st is "TypeError: Component.classes[TvtPwmComponent_CID] is undefined". The 2nd error is; "TypeError:Components.classes[componentid] is undefined." How can I correct these errors?

When opening Firefox 6 I receive 2 JavaScript Application errors; the 1st is "TypeError: Component.classes['''TvtPwmComponent_CID'''] is undefined". The 2nd error is; "TypeError:Components.classes['''componentid'''] is undefined." and upon closing Firefox 6 I receive the following JavaScript error; "ReferenceError:'''M_caFxTBobj''' is not defined."

This issue can be caused by an extension that isn't working properly.
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

When opening Firefox I get a Java Scripts error message and Firefox will not always open

When opening Firefox browser I get an error message from JavaScript Application: "TypeError:components{cid} is undefined. Sometimes the Firefox browser will not open; sometimes it does. Very annoying!!
Richard

This can be caused by an add-on that says it is compatible with Firefox 4 but isn't quite compatible. This thread has more information: [https://support.mozilla.com/en-US/questions/729606 Javascript pop errors stating: TypeError: Components.classes[cid] is undefined | Firefox Support Forum | Firefox Help].
Does that help?

When opening Firefox, I also get a popup page thanking me for installing AOL Toolbar.

Frequently, when opening Firefox 7.0.1 I get a popup page over the home page. The popup page is a Thank You for installing AOL Toolbar. I do not have the toolbar, though I might have in the past. I do not like AOL and want to stop the popup page but have not been able to. I do use Winamp's Toolbar and this could be the source of the problem. If Winamp Toolbar is the problem, I will uninstall it if there is no way to turn off the popup from there. Please assist.

There is some anecdotal evidence that the scripts on the Apple site that are supposed to detect the version of Windows you are running may fail for some users - jumping straight to the "Thank you for downloading ..." page with the installer not having been downloaded. As an alternative, you can go directly to the relevant downloads:
iTunes 12.1.0.71 for Windows (32-bit) - itunessetup.exe
iTunes 12.1.0.71 for Windows (64-bit) - itunes6464setup.exe
There is an alternative downloader for 64-bit editions of Windows here:
iTunes 12.1 for Windows (64-bit — for older video cards)
that seems to address many of the playback issues that some users have been reporting with the full 64-bit version (the alternative installer here is the same architecture as most previous "64-bit" versions of iTunes, i.e., a 32-bit application with a 64-bit installer). The "for older video cards" reference does not seem to fully define the scope of systems for which this alternative works better.
See turingtest2's notes on Troubleshooting issues with iTunes for Windows updates for more details if you're still having problems with installation. This also includes links to the iTunes 12.0 installers if the issues reported with 12.1 suggest it safer to use the previous version.
