Firefox crashes immediately after upgrade
We upgraded firefox so the latest version last week on a few of the PCs in the office. After the upgrade, Firefox continues to fail upon launching. Creating a new Firefox profile doesn't help. This problem does occur with other users that login to the same machine. Uninstalling and reinstalling doesn't help. Safe mode does not work either. It is just a continuous loop of crashing and we can't get past it.
Both machines with the problem so far are running Windows 7 64 bit.

Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
- Download the full Firefox installer and save the file to the desktop
https://www.mozilla.org/en-US/firefox/all.html
If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.
- Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
- (32 bit Windows) "C:\Program Files\Mozilla Firefox\"
- (64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
- 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 personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure NOT to remove personal data when you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.
If you keep having problems then also create a new profile.
Do a malware check with several malware scanning programs on the Windows computer. Please scan with all programs because each program detects different malware. All these programs have free versions.
Make sure that you update each program to get the latest version of their databases before doing a scan.

Start Firefox in Safe Mode {web link} While you are in safe mode;
Type about:preferences<Enter> in the address bar
Select Advanced > General. Look for and turn off Use Hardware Acceleration.
Poke around safe web sites. Are there any problems?
Then restart.

Using your mouse, mark the most resent 7 - 10 crash reports, and copy them. Now go to the reply box below and paste them in.
I cannot start firefox period so I cannot get into safe mode from the help option. I cannot start firefox with firefox.exe -safe-mode either.
Thanks.
Start Firefox in Safe Mode by holding down the shift key (Mac Command key) while starting Firefox.
