I am running max osx 10.6.3 and when i closed firefox i couldnt reopen it unless i force quit the app or quit it completely before closing the browser so i uninstalled and then reinstalled but the problem persisted so I deleted the contents of the preference folder after installing then reinstalled but now everytime i try to open it it gives me an error saying "a copy of firefox is already open. only one cope of firefox can be open at a time". I restarted the computer several times but that didnt fix anything and i can no longer start firefox. I am assuming its because there is a file somewhere telling firefox that it is open but I can find it.

This happened

Every time Firefox opened

I reinstalled firefox

Hello Al.

You may be having a problem with some extension or plugin that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

I cant really get into firefox to disable or uninstall them and while an extension may have been causing my original problem, it isnt anymore. Now its a problem with the firefox system files but I guess I may be wrong.

Finally found the culprit folder. Something in the mozilla folder under ~/library/application support was causing the problem... deleted it, uninstalled and then reinstalled and we r back in the game.

To manage extensions when you can even open Firefox, use safe mode.

It's great that it's fixed, though.

Forgot all about safe mode... I guess I didnt c the Icon for it like you have on a PC so didnt think to use it. Oh well, thanks for the help anyways
