When opened, Firefox screen becomes blue, not a crash, just the whole screen is blue.

It isn't a "Blue Screen of Death", the website doesn't load and the Firefox screen turns completely (no search bars left) tinted blue color that Windows 7 uses. I am guessing this is related to an addon but not sure. Here is a picture: http://i1176.photobucket.com/albums/x328/Deathtomyfoe/MozillaError.png

hello Thomas_Hunt, can you try launching firefox in safe mode by pressing the shift key while it is starting and see if the issue is occurring there too? maybe a theme or hardware acceleration is interfering here...
if safemode is working, you can try disabling hardware acceleration in firefox > options > advanced > general and or disable addons that might cause the problem. it also would be interesting which graphics hardware (adapter description, driver date & driver version) you are using - you can access this information in firefox > help > troubleshooting information towards the bottom of that page... thank you

'''edit: from another user we found out that this might be related to malware, could you see if you have the same addons installed, remove/disable them & run a in-depth scan of your system with security software - see''' https://support.mozilla.org/en-US/questions/940393#answer-377118

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. 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].

hiskebdb,
If it happens when moving an object/text, the issue may be caused by the Chrome Pushbullet extension, see this post #3 by Matt with the solution,

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?

Do a clean reinstall and delete the Firefox program folder before reinstalling a fresh copy of Firefox.
*(32 bit Windows) C:\Program Files\Mozilla Firefox\
*(64 bit Windows) C:\Program Files (x86)\Mozilla Firefox\
*http://kb.mozillazine.org/Installation_directory
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 17.0.x: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Your bookmarks and other profile data are stored in the Firefox Profile Folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.

When opening Firefox I get this message: Type Error: Components. classes ['@software.ru/skype/skypeFfentension;1'] is undefined. I have reinstalled Skype still have issue, Skype will not load, Firefox will ??

I started having this issue when I went to open Skype and it would not react and gave the message below. Then when I went back to firefox I got the above error message, which dissappears when I click OK and firefox will open. Skype still will not open.

That is a problem with the Skype extension. 
You will have to disable (uninstall) that extension if it isn't working properly.

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".

THAT you can't change. Silly of Apple not to provide a setting to back out the animation effects either as a whole or individually.

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.

When opening a file of any type in Photoshop (CS4), the windows will not appear in Ps.

When opening a file of any type in Photoshop (CS4), the windows will not appear. Photoshop will open and I can see the layers on the right but the document window will not come up no matter what I try. I try closing down everything, double-clicking a layer, opening multiple windows, etc.. Any thoughts?

Can you post a screenshot of your entire Photoshop screen with a file loaded in and the layers panel showing?
It helps if we see the same problem you are seeing

It did not do this before the update. Before the update if i had minimized windows they would stay minimized when i opened a new window. Please help ,I would guess it is just a setting somewhere but i cannot figure out where the setting is. Thanks jason

When opening Firefox 4 RC it says connecting for a long time

Usually when I open Firefox 4 RC it will show "connecting" in the tab for sometimes a minute or more. Happens on my desktop and laptop both running Windows 7 Pro 64-bit. It seems to happen every time I cold start Firefox, and it happens a few other times with warm starting it.

Hi there derekmski.
I had this error as well. I believe it's an error caused by the 'TabRenamizer' add-on. This causes 'New Tab' or 'Connecting' to appear in the tab for extended periods of time, even after the page has fully loaded.
If you're running this add-on, try removing it. If not, I'm afraid I don't have any answers.

When opened, Firefox screen becomes blue, not a crash, just the whole screen is blue.
