Firefox no longer starts up. It crashes and stops responding on MAC Monterey 12.7.4 This is as far forward as it will go on this old mac. Everything worked fine yesterday, start up today and no go. I removed the profile and attempted to restart. No joy. So I downloaded a fresh copy and installed it over the old version. No joy. Cannot access profile manager. Removed version and fresh install, still no joy. How to I get it to launch, then How do I recover data from old profile?

Hello! After being away from my PC for a few days I tried to open firefox and got this error:

'Firefox is al actief, maar reageert niet. Het oude Firefox-proces moet worden afgesloten om een nieuw venster te openen' aka 'Firefox is already running but not responding. The old Firefox process must be closed to open a new window'

I deleted the application in windows settings and then redownloaded it. The problem persists. What can I do?

King regards, Anton Siemonsma

'since the update from Aug 20 to 129.02 cannot open lobstr.co on firefox (after 8 captchas get error). Have no problem opening lobstr on Windows or Google. So this has to do with your last update. What do you suggest?

I routinely update Firefox in the classroom on freshly re-imaged computers. The image is very old and has a very old version of Firefox. The machines are supposed to be identical and so is the image.

I have noticed that when I run the installer on each machine, sometimes there is a checkbox about resetting everything, and I have to manually check it and continue. However, sometimes there isn’t. Otherwise my setup procedure is identical.

Is there a startup option to always bypass the checkbox?
