My browser used to work just fine, but today I opened it and this is what it looked like: http://i49.tinypic.com/mbprbr.png As you can see there are no toolbars except for the bookmarks one and the page is black. Same goes for new windows, and when I right-click the nonexistent toolbars a completely black menu appears (it looks just like the pages). The same thing happens even when I try Safe Mode, and I did a clean reinstall but it didn't help.
Thanks for the quick reply. I tried resetting firefox but that didn't work either. And I can't turn off hardware acceleration since I don't have the 'Firefox' button (or any button or toolbar).
Let's try this:
Go to your Start, Control Panel, Uninstall a Program. Remove Mozilla Firefox. Make sure you DO NOT remove your personal information.
Then, Open your Computer, Go to c:/, then either Program Files or Program Files(x86). Find the Mozilla Firefox folder, and delete it.
Now, restart your PC.
Then visit www.getfirefox.com and download and install Firefox from there.
Do a clean reinstall and delete the Firefox program folder (C:\Program Files\Mozilla Firefox\) before reinstalling a fresh copy of Firefox.
Download a fresh Firefox copy and save the file to the desktop.
Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
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.
If you keep having problems then also create a new profile.
You can also try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that works.
