Unable to launch Firefox after update install to version 98.0.2
I have an iMac that is a decade old. Running macOS High Sierra version 10.13.6 That is as updated as I can get on this processor.
I had a normal "there is a newer version of Firefox available" update alert, so relaunched Firefox to update. So on Monday 4th April NZ time i got the update. As usual I got the message [in a dialogue box]: Close Firefox. A copy of Firefox is already open. Only one copy of Firefox can be open at a time.
So far, normal. I closed Firefox, then relaunched. Same message. Did a logoff on my computer - same thing Did a full shutdown, login - same message. I got a bit radical - I dumped Firefox, deleted Trash. New installation (version 99.0.1) Same message;Close "Firefox. A copy of Firefox is already open. Only one copy of Firefox can be open at a time."
Currently using (newly installed) Edge for Mac, until this problem can be sorted; I hope it is brief, I have used Firefox for most of the years I have had a computer.

The funny thing that has happened is that, in answering the posting, Firefox opened the reply window; not Edge, where I had originally posted the query/problem. I am about to shut down and then relaunch Firefox; the problem may be no more? [fingers crossed] - let me see....
... and it has worked. Whatever has gone on in the background has resolved itself. I just don't have all the bookmarks I had anymore, and will need to reload all these, and the passwords [where needed], it will just take time.
Glad to back with Firefox.
p.s. I would like to cahnge Zioan's post to a favourable thumbs up, but I cannot edit this - sorry Zian.

You can try uninstalling and reinstalling Firefox. Note that your old data will likely not be kept.
- In Applications in your Finder, locate the Firefox apps.
- If there are many of them, this could be the problem. Otherwise proceed to step 3. Move one of them at a time to Trash until the problem is fixed (you can always restore Trash items).
- Move Firefox to Trash and download a new release. Install it.
I recently got that message and was able to restart Firefox after deleting the lock file. On my Linux system that is in the profile folder.
I have iMac running system 10.13.6 As stated at the beginning, I had deleted Firefox, and then downloaded a fresh new install, which gave me the same problem.
I cannot find anything in the Appllication's Contents remotely like a lock-file; But thanks for the information.
