I recently upgraded FF on this computer and can no longer sign in to my att.net email account, although I was able to sign in on another computer on FF earlier today. I just get an error message and Att can't help...is there a setting that has me locked out? I can also access email on other browsers just not the FF version on this computer.

As of February 13, 2025 the front page of the Washington Post website does not load correctly in Firefox 115.20.0esr in Mac OS 10.13.6. The problem persists even in safe mode. Thank you.

Why does Firefox intermittently fail to connect to the Newsmax website? I get a Secure Connection Failed message. It happens only occasionally, but enough to be an annoyance. What's the problem and how do I resolve it?

After the recent bunch of windows updates i started noticing youtube loading much slower and other websites acting strange. Just now i tried to look at a link https://steamusercontent-a.akamaihd.net/ugc/47948470127416586/912CDEE3AD8B94CF3122B7338E89E24C9B6EC29D/

I get "No video support and MIME type found". I have uninstall/reinstalled, checked codex, disabled addons and downloaded Microsoft windows media pack, then restarted the computer.

Nothing seems to work. But i had to reinstall Firefox again because all my tabs would crash after the last reinstall.

I have set E:\ as my default download location. However in some cases Firefox does not respect my choice and silently downloads stuff to C:\Users\Name\Downloads. I really hate this. One example, a pdf downloaded from here https://scribd.vpdfs.com/. Please fix it. Thx.

This issue just appeared. Video will not play in Firefox. Windows10 PC, up to date with latest versions, as is Firefox. There is no error message or code. Just the spinning wheel. I see other people are having the same issue but I haven't seen a solution. Any ideas or help appreciated.

Attachment is a screenshot shows task manger shows there are 64 open files open, when I have only 4 windows open. What would causing this?

Over night Firefox closes and close all my open windows. I need the windows remain open.

Thank you for sharing your wisdom with me.

I reinstalled windows yesterday. When I installed firefox and signed it, everything was fine. However, this morning, it seems to have removed 80% of my bookmarks. When I try to restore from the bookmarks yesterday, it just gives me the ones that I have this morning. I had tons and tons of resource bookmarks for my work that would be almost impossible to re-find in some cases due to the current state of search engines. Is there any way to salvage them? It seems like sync believes they never existed, but it DID sync them yesterday??? Please help.

Websites such as the Sites above are not working in Firefox or other Open Source Browsers. I am being forced to use Chromium in this case to complete payments and add items to the DMV Cart and complete a payment for example. I do not want to have to do this. I do not want to be forced to use a Closed Source Browser such as Microsoft Edge or Google Chrome or Apple Safari. Or, Even the Open Source version of Google Chrome Chromium. Companies like PGE are deciding to drop support for Firefox as the State not enough users use Firefox. They are forcing the market to use a Non Open Source Browser. This is a Problem. This is not good for Competition and the Internet as a whole. Not good for me as I am a Linux User. The PG&E website does not even load when using Firefox. The DMV site loads but does not allow one to complete any Payments for Example. At this time one can only view Information on the DMV website.

Windows just had an update, in that when I did it now Firefox has no sound at all in Youtube, Disney plus or any other site.

Now I did my own trouble shooting, games have sounds, my music player (winamp) has sound, I downloaded chrome and I oped volume mixer and played a video in that, there was sound.

I do the same thing in firefox and there is no sound, and in volume mixer where the lines go up showing the volume as it plays, it did it for chrome but not Firefox.

So there is no issue with my head set, my computer or my sound, it is firefox alone.

I use Firefox 134.0.2 (64-bit) on Ubuntu 24.04.

Some (not all) web sites show up only after a delay of exactly 30 seconds. The attached screenshot shows that this delay is due to DNS resolution. This behavior is reproducible by simply closing Firefox, opening it again and entering the same web site once more. Once this initial delay of 30 seconds for DNS resolving has passed the web site can be browsed normally.

Using Google Chrome, Opera or even the Tor Browser on the same system works without any significant delay. Also a DNS lookup from the console returns data almost immediately.

As the delay is always exactly 30 seconds this looks like some DNS resolver timeout only showing up when using Firefox.

Neither starting Firefox in Troubleshoot Mode nor (as often suggested) disabling IPV6 for DNS by setting network.dns.disableIPv6 to true did help.

Any idea how to fix this 30 seconds delay?

Many thanks for any help, Felix

Hello, vinted.com/ vinted.co.uk has been throwing me all sorts of strange errors and security concerns over the past 4-5days. Any ideas? Thanks for your help!

I'm experiencing an issue with Firefox where my saved passwords from my desktop aren't syncing to my Android phone. Pressing the "Sync Now" button doesn't trigger any action. I've tried several troubleshooting steps, including removing and readding the device, force stopping the app, clearing cache and data, and manually syncing again, but nothing has worked. It seems like a bug. Any suggestions?

the tab groups feature doesn't work. WHen i drag one tab onto another, nothing happens, other than the tabs go back and forth. Can't put one tab over another and no group is created.

Installed 134.0.2. Bookmarks disappeared. Went to restore backups, receive message "unable to process the backup file". All of my bookmark backup files receive this message when I try to restore.

my wife's copy of Firefox picked up a virus. After trying several other things, I saved the profile, uninstalled FF, and installed the latest version. But when I tried starting FF I got an error message: Your Frefox profile cannot be loaded. It may be missing or inaccessible.

My monitors are QFD ( 2560 x 1440 ) and I use font scale 125%. With the most recent Firefox these fonts are garbled. They do not display properly. I am using MS Edge for the time being.

Hi,

I am the developer of the Dictionary Anywhere extension which is a Firefox recommended extension. Recently my extension stopped performing up to its expectations due to backend changes in public API that it uses to find meaning of the words.

However, I am unable to modify the code of extension to fix the issue as I am not able to login to my account due to it being behind MFA, and I have lost access to the phone which contains those MFA codes.

Can something be done here, to allow me to update the extension to rectify the issue that 50k users who use this extension regularly are facing? For example, can the extension be transferred to another account through which it can be updated, lots of users are suffering as the extension is not working. I have access to the source code of the extension .

Thanks and Regards
