Some web pages did not load correctly. (on Imac). Deleted Firefox and moved Profile to another drive to backup. Downloaded new Firefox. When I try to install, I keep getting this message-"A copy of Firefox is already open. Only one copy of Firefox can be open at a time." I went in and searched for all occurrences of Firefox or Mozilla and deleted.

It will still not load.

See:

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.

I cannot get Firefox to run now. I backed up my Profile to another drive. Cannot create a new one as Firefox will not run. It says there is another copy running. However, I have deleted all Firefox and Mozilla files and downloaded new. When I try to run it, I get the message to close Firefox as two cannot run at once.

I did create a new Mac account logon and can run Firefox there, so something in the other account is showing Firefox is running.

I also checked in ACTIVITY MONITOR and in SETUP and there is no Firefox or Mozilla running.

So, where can this bug be hiding????
