Hello. Firefox accessed from doc & from Finder is not responding. Toolbar & FF (Firefox) browser window slowly opens to white unaccessible browser screen. Must force quit to close FF. Tested FF with different user on same computer and it works fine. Crash has been consistent & unchanged over the last 3 days.

Got lost in Library FF Profiles and could not locate the file that online support-thread said should be deleted. Did a Re-installed Firefox (tried anyway), dumped cache files and ALL plug-ins. Still FF (and Safari) would not open.

Safari browser was crashing at the same time and found that an alias needed to be place on Dock since the Dock link does not update like the Safari app link did in Finder. Safari is operational now.

Crash report is not appearing in FF crash report file only 1 months old crash report. Had no optionto send report to Firefox, but auto sent to Apple,

In added link = This is a copy/ past of "problem report"? automatically sent to Apple at each FF crash.

FF provided troubleshooting.xpi file will not open (no program to open with o Mac) and cannot access FF browser Help to provide further info.

Thanks for your help. Report As follows.

It sounds like the user profile is causing the problem.

Create a new profile and see if there is a problem.

If you choose to move data from the old profile, copy ONLY the add-ons.

Try to repair the disk permissions:

Try to remove the Firefox plist file (org.mozilla.firefox.plist).

Go to "~/Library/Preferences" and remove the plist file for Firefox (org.mozilla.firefox.plist)

You can check for corrupted and duplicate fonts and other font issues:
