Hi,

I’ve recently noticed that after a Firefox update, the browser has become very slow and unresponsive whenever I open multiple tabs, around 5–10. Before this update, I could open many tabs without any noticeable lag.

Now, new tabs take a long time to load, scrolling within open tabs feels choppy, and sometimes Firefox freezes for a few seconds before responding again.

I’ve already tried restarting Firefox, disabling extensions one by one, and clearing the cache, but none of these steps have improved the performance. I’m using Windows 10 and the latest version of Firefox.

Could anyone suggest what settings or troubleshooting steps I can try to fix this slowdown?

streaming sites that load on chrome, opera and brave do not load on firefox since the last update, the throbber is the only thing that loads. Running win 11 pro on a powerspec computer, 32 gig ram, onboard graphics, intel core I9 processor 12th gen I believe, has been checked and not one which had the issues

Some videos work perfectly fine, however for some videos audio lags behind the video. The same video file perfectly works in Chromium as a control test. Example file is MP4, inside was initially h264 video with AAC audio, for test I re-encoded video to be svt-AV1 with AAC / flac as well - no difference, audio still lags behind. Local players (mpv) and Chromium works perfectly. No plugins which can affect it - for testing disabled them all. I really try hard to like Firefox but this thing is a real bummer. Any ideas what can be causing? P.S. I tested both firefox compiled from source and binary package provided by my distro. Linux system if that matters.

On outlook.com sign in with password does not work. It gives "Please retry with a different device or other authentication method to sign in." Works fine in edge.

Noticed the bookmarks error message at the top of the browser page then looked to find they were gone, no troubleshooting methods have worked and I don't seem to have any backup files. Bookmark manager is blank and there are no selectable options?

Firefox: When printing out - or saving onto PDF - a website, its URL is placed in the footer or the header, depending of the settings. Unfortunately, when the URL is longer than half of the width of the printed page, it is truncated. How to avoid this truncation?

Hi, I use Firefox as a primary browser on multiple PCs, so want it to remember a couple of addresses & payment methods for easy daily useage. However, I also access one business domain & when using that website only, I don't want Firefox to offer/remember/anything when it comes to addresses (which will be customer addresses) or payment details (again, for customers). Other autofill, like suggestions for some form fields would ideally still work.

Is there are way to make one domain exempt from address & payment saving/retrieval?

Thanks.

I have a profile that I had copied from my main profile, which is connected to an email and synced. This second profile is unsynced, and it won't let me sign into my account because that account is connected to the main profile. It says I need a separate account for a separate profile. Fair enough. I try to make an account. It says I cannot sign in to the new account because the profile is synced to the old one. Very annoying to be given instructions that don't work. So, I make a new profile and sign in to my new account on it. It works. But now I don't have my bookmarks and passwords. So I find instructions on backing up my account and copy my secondary profile into the new profile with the new account. It logs me out and is now giving me the same error! (the backup was successful though) I don't want to have to copy and paste all of my passwords and things into a new account. Is there any way to make my secondary profile syncable?

To whom it may concern,

After the latest update I was met with a blank profile, no saved data, even when syncing with my Mozilla Account. I followed the back-up instructions by the support team described in the forums, but it wasn't enough. Common sites I frequent like youtube and gmail were not indexed, the passwords and logins were nowhere to be found. I really don't get what's going on, or why would the Mozilla Account wouldn't recover the data, while leaving that to profiles. Is there any way to recover it further? Or even disable profiles?

Thanks in Advance,

When Facebook creates passkey Firefox asks for an USB to be inserted. I have tried to disable USB in the settings ("security.webauth.webauthn_enable_usbtoken","false"). But then Facebook just gets into a retry loop and I can't create the passkey. I use Windows 10, and USB is NOT enabled as an authentication option. I need to fix this as Facebook nags me (in e-mail) to create a passkey.
