"Refresh" stopped app working and now get a message when I try open the app saying copy of forefoot is already open which it is not.

Posted

I like Firefox but sad to say that I have increasinlt wasted much time lately with its crashy ways and I made the mistake of using Refresh today.

Now get a message when I try open the app saying "copy of firefox is already open" which it is not true and it is not showing as running on the system.

I have tried reinstalling and it makes no difference.

I dont have an IT engineering degree but how do I fix this before I just give up and walk away? Thanks.

Chosen solution

UPSATE RESULT

This fixed it quickly without all that complex stuff.

Go to command prompt type in:

/Applications/Firefox.app/Contents/MacOS/firefox-bin -P

A window opens with proudly, i had two.

One was just titled 'default' while the other was 'default-9999999999999'. 13 numbers.

Delete the default profile and restart as it asks. Simple.

I am indebted to

sylvester-13 for his post:

On my Mac I'm getting the error message "A copy of Firefox is already open. Only one copy of Firefox can be open at a time"

This really should be in Mozillas own list.

Thanks Fred McD. Yes fixed as I outlined.

The thing is that I didn't know the issue was a profile problem at the start, so I wouldnt have looked for that on the help list. I thinkl the key here is that the " running a copy " message should make it cleaer that it ,ay be a profile issue and that could be on the pop up warning. Would have saved a lot of time.
