Then I ran FF 3.6 with that profile. Worked fine. Then I closed and restarted FF 3.6. Now I got the error messages: GetCharPref('id') failed GetCharPref('version') failed FF died immediately. Reproducible: Always Steps to Reproduce: 1. Set up a new profile, say 3.6, with FF 3.5. 2. Copy the 3.5-profile to the new directory. 3. Start FF 3.6 with -P 3.6. 4. Shutdown the browser. 5. Start FF 3.6 as in 3.) Actual Results: FF does not start. Expected Results: FF should run with the copied profile.
try safe mode, could be some add-on is not compatible or causing issues. http://support.mozilla.com/kb/Safe+Mode
also, it's possible you did not copy the profile correctly. did you copy it while both instances of the browser were closed?
Thank you a lot, safe mode works fine. I will have to try the extensions one by one.
OK, for the record, keyconfig breaks FF 3.6. Everything else works very fine here.
thanks for getting back to us. you can report to the extension developer if you desire.
