Fórum podpory Firefox

I'm using Firefox 124.0.2 (64 bit) on Windows, and every few days I get the error about using an older version of Firefox, with Exit or Create New Profile options. I then run "firefox -allow-downgrade" from the command prompt and everything works fine... for a few days, when it happens all over again. This only started happening a couple of weeks ago, but it's getting really annoying. How do I stop it (short of using something like Waterfox or Brave).

I am unable to reach Facebook on both Firefox and Waterfox.

Other browsers (Opera, Edge, Chrome) are able to access Facebook.

I can access other Meta-owned sites (Messenger.com, Instagram, Threads) on Firefox and Waterfox.

This issue exists on both my desktop (Windows 10) and laptop (Windows 11).

This issue does not apply to Firefox for iOS or the Facebook app.

All apps and OS's mentioned are up to date.

This has been going on for over a week now.

Starting with my bank's web site, my user name/password is being challenged. I can't bank. Elsewhere, where my desk top has always been recognized, I'm now forced to log in each time...and I receive an email that a new device has just logged into my account. All of this suspiciously coincides with a recent browser update. On my bank feedback it's showing as Firefox "125"...when all previous logins were recorded as Firefox "124". Help!

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

I always want the address bar suggestions to start with my bookmarks. Is there a way to control the results? I remember there was something in about:config previously.

I had a few issues with Hotmail and Firefox in the past as described in other posts. Now it has stepped up a gear. I can use the internet for anything, but the moment I open my Hotmail account in Firefox my Lan card stops working. At first I had no idea it was Hotmail, I tried everything from switching cables to using wifi only. When it happened on wifi I realised every time I went into Hotmail on Firefox my network card stopped functioning and I had to restart the computer. The thing is, when I use Hotmail through Microsoft Edge nothing happens and all is well with the world!!! No network card shutdown. I could read between the lines but I'm no conspiracy theorist, however, I don't think the problem is with Firefox. Is there any solution? I don't use Edge and I don't want to start.

Concurrent with the most recent automatic windows update (may or may not be the problem), Firefox with duck-duck-go will not go to almost any site. All I get is a spinning icon or a blank page, not even any error messages. This was even true trying to go to this page until I restarted in trouble shooting mode. Until I can get Firefox working again I have been using Chrome with duck-duck-go. Note any search, i.e. 'hotels in Italy' or even 'MSN' do the same: spinning icon or blank page!! Any help would be appreciated. Also I noticed that my bookmarks were missing and there was no bookmarks drop-down on my tools line. I have run malware bytes and it showed clean, same with CCleaner. I have re-installed Firefox; no difference. Please help. and also, any way to find and replace my extensive bookmarks list? I have reduced my privacy to near zero and turned off firewalls and all limits I could find while testing for that. That did not change anything.
