Hi. Recently, a old issue has comeback on my firefox. When I load youtube video, or a twitch livestream, at 60FPS, and I scroll down the page, the scroll "lags" until the player is off screen. By lags i mean it slows down the scroll and is no longer smooth. This is an issue I've had before and had successfully dealt with by accessing about:config and turning media vp9 off, but it has returned fairly recently, since I do not remember this issue happening before the last week, maybe two. Another issue, also on youtube, is that when I scroll down through shorts, sometimes after a couple of videos, the browser will visually freeze entirely, but will still allow me to click things on the page and also play sounds. After about 20 or so seconds, it will unfreeze and work normally.

I understand that this issue, atleast the 60fps scroll lag, has been an issue for a while and I have tried multiple fixes for it, changing various boolean settings, refreshing firefox, updating my Nvidia drivers to the newest via nvidia app which i should add has never been an issue for the past few months and has worked flawlessly and my nighmarish evening of troubleshooting ended with me completely fully uninstalling firefox and redownloading fresh, but the issue presists.

It should be noted that on other browsers, I have no such issue. Im not sure if mentioning this is some sort of taboo or persona non grata, but i also downloaded and tested Waterfox, and it also does not have this issue. The only band aid fix I found for the moment is that turning off Hardware Acceleration fixes the scroll issue, but it causes awful screen tearing, which is just as bad and distracting.

So to my understanding, 3 potential things are happening. This issue is just in my head Something on my pc is dying and I have a mechanical or software problem Or finally, there is some issue with a recent update, either with firefox or maybe some driver somewhere causing an issue. It just upsets me greatly due to this being a relatively new issue. As stated I have dealt with the scroll lag before and did find a permanent fix, and firefox has since worked literally flawlessly for months/years. But now, somewhere within the last week, maybe 2, something has gone wrong. I hope this gets fixed in an update, or if others have this problem there is a fix. Thank you.

up until this latest version you could delete your search history with a simple right click. This option no longer exists and there is no easily found way to delete "Search History" where did it go? will it be returned? is Search History no longer delete able?

I use BT internet for emails. When composing an email I type the addressee into the To box. The full address pops up but when I click on it Firefox only copies in the first few letters. The address is then highlighted in red as invalid. I have been in touch with BT who say that this is a known Firefox problem. I found this to be true becasue my email service works fine in Chrome. However Firefox is my preferred browser so I would like to get this fixed. Thank you.

From some long time the is no sound when i open music or movie in browser dont know whats happend - restart or new version of browser did not help at all - other browsers everything works fine

I'm getting totally disgusted with Firefox, Windows 11. FF updates automatically. More and more websites will not open when I'm using the browser, and they open just fine when I switch to another. Since I have used Firefox ever since its inception, it's extremely distressing. It doesn't matter if I turn off ad blocking and tracking software. The latest site that won't open is Substack, which works perfectly okay using the Brave browser. This is probably the 10 instance this month of a website that does not work with FF, including once that always did work just fine.

Other changes are also annoying, but I'll save them for another complaint.

I don't have VPN option in the toolbar settings, there's no settings featuring VPN, I didn't see VPN setup prompt. I have Split View tho. What do I do? Is built-in VPN not available in my country (I'm Russian)?

Hello,

   The "data_collection_permissions" property is missing

In my manifest i have "data_collection_permissions" to "none".. Uploaded my manifest screenshot, can you please help me get this working.

I'm not sure what happened. I restarted my laptop and when I tried jumping onto Firefox it didn't have my normal accounts on it they were gone and I had to make a new one which means all of my bookmarks are gone, none of my accounts are logged in I am freaking out! What happened?!?!

Firefox update removed all my bookmarks, recovered and windows update screwed them all up. Can;t find a solution to my issure..........

I updated Firefox and my search in the middle of the screen disappeared. I have tried about:config and switched it to false and the search bar still doesn't appear. How can i fix this problem

I'm getting the message "It looks like you have a browser extension that might be interfering with Microsoft Advertising tools. Please disable this extension." I don't have any extensions. I can't use their site until this is fixed. I chatted with Microsoft and they directed me to Firefox.

I am encountering more and more websites with problems they attribute to Firefox. Many of them recommend using Chrome or Edge and some insist upon it or they will no longer support problems. Direct TV will no longer work with Firefox at all and they will not fix it. Several of my other regular websites will work partially, but have pages that simply will not work with Firefox. I have resisted using Chrome or Edge for years but it is getting harder and harder to do as on line systems continue to have problems with Firefox and their only suggestion is to use Chrome (which works when Firefox doesn't). Any ideas/suggestions?

I am using Firefox (March 2026 version) and BT internet email wit Win11. Since January 2026 update I have problems entering email addresses that are present in my Contacts list. When starting the cursor goes to the CC: line before switching to the To: line. Then when I start entering an emaiil address that is in my contacts list an option(s) show and when clicking on the correct one instead of it displaying in full in the To: line it shows the first few characters in a red in a box with an x at the end. I then have to delete this and fully type in the full email address. This is very annoying and time consuming. I had hoped the recent update would have fixed it, but it has not. Could you kindly investigate - many thanks
