What exactly did you copy?

Sounds that you have a file profiles.ini file that no longer points to an existing profile folder.

Hi,

I can't get in to a firefox folder to delete profiles. It say a copy is already running, and there is now copy to open! I'm really frustrated, spending hours on this.

Create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: Make a new profile":

If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Hi Cor-el,

Thanks for your help. I can't open anything in firefox. I can't change a profile. When I trash I'll traces of firefox on my mac, restart the mac, then re-download firefox, I still get the message that a copy is already open. But then, I can't get into any facet of the application to change or delete profiles. No one is home. what can I do?

Did you check for the presence of a file profiles.ini and delete that file?

Yes. But could find nothing. I ended up calling Apple Care who was extremely helpful and walked through the bowels of the finder library directories to clear out all remaining firefox debris. Found some folders only that way, none could be be found through a firefox interface. Restarted computer and downloaded a yet again fresh install. Seems to be working now, after finding and deleting hidden files.

Thanks for you help Cor-el, however the Mozillzzine Knowledge Base links were completely useless. Not a single one was possible to do, as firefox would not open.
