Windows 7 service pack 2 and Firfox are now not compatable? Is there a fix?

Question

Windows 7 updated today. Firefox no longer works. States not compatible. Uninstalled and reloaded. Still no go. Is there a fix for this?

Answer 1

The answer can be found here from a Microsoft thread (credit to Millie, not myself):
After uninstalling KB2670838 IE9 and Firefox worked again, I then installed IE10 and found that the IE10 installer re-installed KB2670838 and Firefox would crash again but IE10 did not crash.
After some searching, I found the Troubleshooting page at mozilla.org

Start Firefox in Safe Mode (hold the shift key when starting Firefox) then turn off hardware acceleration:
At the top of the Firefox window, click on the Firefox button and then select Options At the top of the Firefox window, click on the Tools menu and then select Options On the menu bar, click on the Firefox menu and select Preferences...At the top of the Firefox window, click on the Edit menu and select Preferences
Select the Advanced panel and the General tab.
Uncheck Use hardware acceleration when available.
At the top of the Firefox window, click on the Firefox button and then select Exit At the top of the Firefox window, click on the File menu and then select Exit On the menu bar, click on the Firefox menu and select Quit Firefox At the top of the Firefox window, click on the File menu and select Quit
Start Firefox the way you normally do.
Firefox does not crash on startup now.
