Will Firefox run in Safe Mode for a minute or two? If so, please try making this setting change:

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the search box above the list, type or paste d11 and pause while the list is filtered

(3) Double-click the layers.d3d11.disable-warp preference to switch it from false to true

If you can make that change, does it make any difference? (Suggestion based on the bug linked in your crash reports.)

Sorry, I forgot to mention holding down the Shift key when launching Firefox to try to start up in Safe Mode.

If that isn't possible you can try pushing this change into Firefox by adding a line to the prefs.js file.

To access that file, you'll first need to open your profile folder.

In the address bar of a Windows Explorer window, or in the search box on the Start menu, or in the Run dialog, type or paste the following and press Enter:

%APPDATA%\Mozilla\Firefox\Profiles

Usually there's just one folder here, so double-click into that. If there are multiple folders, double-click into the most recently used one.

Next, look for a file named prefs.js (if you see a file named prefs with a type of JScript, that's the one -- you can stop Windows from hiding the .js extension by following the steps in this article: http://windows.microsoft.com/en-us/wi.../show-hide-file-name-extensions).

You can edit prefs.js by right-clicking the file and choosing Edit, or Open in Notepad or a text editor of your choice. (It would be best to avoid using a word processor that might modify the plain-text nature of the file.) Paste the following line on its own line at the end and save your change:

user_pref("layers.d3d11.disable-warp", true);

That should be in effect the next time you start Firefox.

Any difference?

That solved the problem....thanks a bunch
