Forum d’assistance Firefox

How do I turn off those annoying "update available" notifications/reminders that keep popping up? I've gone into Settings, and in the Updates section firefox only let's me select auto updates or check for updates. I searched online but couldn't seem to find anything about how to disable the notifications all together with the newer version of FF. It's driving me crazy, thinking of switching browsers because of this. Thanks in advance!

Since upgrading to the last version, 125.0.3 I'm getting tab crashes. Is there any way to go to a previous version? I have not had any issues with the websites I'm visiting until this new version of Firefox.

When I view my bank statement in Firefox, everything appears fine, but when I print the statement, all occurrences of boldfce "S" on the printout are blank. This problem does not occur with Google. Running macOS Catalina, all maintenance applied, Firefox is at 125.0.3.

Problem with using space bar when trying to post replies on YT or other sites. Can key text, but space bar does not work. On Google search page, can get only one space between words. Tried 2 different keyboards w/same problem. Doesn't seem to happen on Chrome or Safari. Re-installed Firefox with same results. Any thoughts, please? Thank you.

Ok-So this popup window popped up when I returned to Firefox. I don't think it's legit and I am wondering how I go about blocking it permanently. I searched the settings but didn't see where I could post the URL so that is why I am posting this here.

I copied the URL but I don't want to post it here in case it could do something to someone else's system. But here is the screenshot. Please advise me what I need to do. Thank you! TGIF!

I am on a Mac running Sonoma.
