Mozilla Suite : Issues : Start
Mozilla will not start
This can be caused by any number of reasons (corrupt profile, incompatible extension or a computer crash). The first thing to do is to create a new profile. If not for other reasons than to make a testcase and see if the problem persists. Another thing you could do is to check your extensions. Rename the chromefolder in your profile /shut down Mozilla first). A new empty foilder will be created on the next run.
If you have tried this and feel that a completely new and clean install is required this is how you should do it:
. Backup your Profile
. Start mozilla and move any mail in incoming folders to a local folder (important)
. Uninstall Mozilla
. Delete the GRE directory (folder) (important) (C:\Program Files\Common Files\mozilla.org\GRE - in Windows)
. Delete the Mozilla installation directory (software folder)
. Reinstall Mozilla and configure it
. Copy the files back from your backup Profile to the new profile (prefs.js and/or user.js should not be copied since the old paths are stored in there and if Mozilla is not working correctly, chances are that they might be corrupt)
To get your favorites/bookmarks, mail, cookies and username/password back you should copy the following files/folders:
abook.mab - addressbook
bookmarks.html - bookmarks
cookies.txt - cookies
cookperm.txt - permission, cookies
key3.db - Usernames/passwords
12345678.s - (named randomly) usernames/passwords
training.dat - trained spamfilter
<DIR> Mail - your mail
<DIR> News - your news
