I-Firefox Community Forum

I do not want Firefox to be my default browser, nor to I want it to start when the computer is started. I DO want it to use the same tabs & windows as the previous time I closed it.

But every time Firefox updates automatically, it resets those setting back to te default. How can I get it to keep those setting?

My firefox profile keeps showing as repeatedly being deleted then saved in one drive - see screenshot. It's using a lot of memory anyway - nearly 3GB currently with 10 tabs, i've tried most fixes on https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-or-cpu-resources

I don't think it used to do this repeated profile deleting thing - any suggestions?

Lately, after last firefox update, whenever I start Firefox, it loads normally but when I click to open a website it freezes with a not responding message. I have waited for 10 minutes before and never responds. Even opening in troubleshooting mode it won't respond.

When I try to watch videos on YouTube using Firefox the sounds never comes out, only the video runs, I tried changing so many setting but it is not working, and the issue is only with the videos from Firefox.

Since my last 'Firefox' update, I am unable to connect (get logged in) with my bank online. It says...'routing...', but never connects. If I use Chrome or Edge to log in it works perfectly. Firefox is my preferred browser but that may have to change. I have Windows 11 as my OS. Yes, this has happened before when Firefox updates, but eventually it gets corrected, then, when a new update hits, the problem is back. Mozilla...please fix this, it happens with almost every update!

Please see attached images that show my settings for DNS over HTTPS set to cloudflare (default) i have to add exceptions to this for multiple sites that do not open. these websites either show me SSL errors or they completely stop opening entirely. what could be the issue here? the websites open completely fine once i turn off this feature or use another browser.

Ich will diese "KI-basierte E‑Mail-Funktionen für alle" nicht eröffnen bzw. kein Konto dazu einrichten; seit rund 2 Wochen taucht diese Seite "KI-basierte E‑Mail-Funktionen für alle" jedesmal auf und ich habe die grösste Mühe, endlich zu meinen Mails zu gelangen!!

Wie kann ich "KI-basierte E‑Mail-Funktionen für alle" einfach wegklicken?

Danke für Eure Hilfe Hansueli

This keeps popping up on my website when I'm trying to watch movies or TV: Server Not Found. Firefox can’t connect to the server it's happening when I press any movie sites or TV shows, I've even gone to the settings and done no proxy and it's still not working, can you tell me how watch movies and TV's because this gets popping up Server Not Found. Firefox can’t connect to the server I am not a tech person says simple jargon will be, appreciated thank you.

Youtube videos are not playing when clicked, it needs a click to play button, which is tiring and wanted to quite firefox if not fixed. When playing youtube videos, where we click on another video, it opens and play for 2 seconds and then it stops, want the user to click the play button to continue, this is unwanted, please make this an option for those you want that feature. I tried to turn it off in autoplay, but there is no options to do so.

Good afternoon!

I am writing to you regarding the blocking of my Mozilla account. The block occurred on August 5, 2026, after which I have been unable to use my login credentials to access the system.

I have constant access to the linked email. Prior to the block, I was able to log in successfully from my tablet, but when I tried to log in from my laptop, I immediately received a block on the first attempt. No verification code was received via email, nor did it appear in the spam folder.

I kindly ask you to investigate this situation and assist in restoring access to my account. I am ready to provide any additional information if required.

Best regards, Irina Walther

Hello and I hope you are doing good,

Sadly for me it is absolutely not the case It has been a few days since I can't use Firefox at all. When I try to open it, it tells that there is a "side by side error" and that I should use sxstrace.exe. I did that and it tells me that It can't find mozglue, mozglue.MANIFEST, mozglue.DLL. I use Mozilla in French (it is my mother tongue), and it can't find them in French, English or in Neutral :

Thinking it was also linked to the Redistribuables Microsoft Visual C++, I just downloaded all of them again.

My version of Mozilla is 152.0.6.595 and I am on Windows 10.

Please I really need your help and don't want to lose any of my tabs, bookmarks and passwords as I was making very important research for my PHD studies.

Real thanks in advance for your help.

This is a recurrent problem. I'm online with many tabs open, when all of a sudden they disappear and when I try to recover them by going in "history" [using the three lines at the top right of screen], and then selecting "recently closed tabs", and then try the "restore tabs", nothing happens! Previously, this had worked to offer me a way to reopen those tabs one-by-one, but now it doesn't restore anything. ALSO, I used to be able to shut down my computer, wait a few minutes, and then restart it, and would be offered a "restore session" option when the computer restarted, but that didn't happen today even after trying this twice.

I was once shown how to restore tabs by going up to the top right of the screen, but cannot remember how to do this. Can you please help me from loosing tabs, and my mind? Thanks.

Has anyone seen this behavior? Is it really a browser issue or an extension one? Is it a config issue or a bug? I'm juggling 2FA settings on slack for a per workspace basis, plus to Bitwarden confusing different workspaces I'm also having issues with saving updated passwords into Bitwardens vault I'm also logged into my Mozilla account I'd like help troubleshooting this, thanks

While Using Youtube : from the starting page (that comes up with multiple Clips displayed), I attempt to do the following: By selecting Open Link in a new tab, or Open Link in Split View (So I can Watch a specific clip without loosing the original displayed clips on the starting "face Page") ...the selected Opened Link Immediately Becomes Greyed Out And Refuses to Play the the Clip. To watch that clip I must close the video clip that I selected to then return to the original opening page to then Move the pointer back over the smaller box-clip that I want to watch, leaving the pointer on that clip is the only way to watch the clip. This Just Started Happening Recently...... This is Happening Every time..... Apparently, if you want to watch ANY of the displayed clips from a Start "Face Page" you can Only watch by hovering the mouse pointer on that specific Small Box Clip on the starting page...I can't bookmark that page without selecting the page to another Face Page, which then looses the smaller multiple clips on the original face page that I started on.
