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.

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

Firefox only works properly if my VPN location is in Canada, but I'm in the US. If I switch my VPN to a US location (where I live), Firefox often does not work properly. I get news, ads, etc., that assume I'm Canadian. And often a website will not open. I need my VPN location in the US to access any site I normally do.

I can't access FSIS website which I need to do so for my job. This is what I get

"Firefox can't connect to the server at usda.gov Try connecting with a different device Check your modem or router Disconnect and reconnect to Wi-Fi"

I can't do any of those things because they make absolutely no sense. Nothing is wrong with my router, Wi-Fi. It's your program.

Emails viewed in Firefox with Link to YouTube wants me to log in to YouTube when I click on the link in the email.

I receive a weekly email with a featured bird that when clicked should show me a video of that bird. Before the most recent FireFox update I would get a page that wanted me to log in to YouTube; but, there was no way to do so. Now since the update it works-takes me to the video and runs the video.

Was not working last week but since an update it does work. This is an on and off again problem. I have contacted the people who compose the video with no solution on their part; but, in a few days or weeks when you update your browser it will work! Then with another update it won't work. Off again and on again.

Hi, I use a website called Slickdeals which has a lot of thumbnail photos showing the product on the homepage.

Firefox seems to have a problem with it where Chrome does not.

Scrolling fast throws it off...the screen turns white and I have to wait for the images to load. Also, the scrolling tends to get choppy while using my touchpad scroll.

I've tried disabling hardware acceleration, disabling smooth scrolling, and clearing cache/history.

Sometimes the cursor lags about a second from the arrow to the hand pointer on links to click.

I have fast FIOS internet and a laptop with 16 GB RAM.

Thanks!

My firefox has been closing while I am away from my computers. I have a few computer running linux (Ubuntu 24.04) and one in mac osx (Big Sur). Usually, I can start firefox and it will remember my tabs which is annoying but still manageable. However, once in a while, (which happened yesterday), all the firefox closed on all the computers and it forgot my tabs when I start firefox again.

I have already set app.update.auto to false on all of the firefox instance prior to this incident to avoid firefox update would close out firefox itself. So if anyone has any idea of what to check to see why firefox keep closing and/or why once in a while it will not remember my tabs, I would really appreciate it.

After updating to version 149.0, videos on hdrezka.tv do not start after clicking the play button.

Steps to reproduce:

1. Open any video on hdrezka.tv.
2. Click the Play button.

Actual result: The player stays inactive or shows a loading icon.

Expected result: The video should start playing.

Note: I have tested this on version 148.2 and it works perfectly. Upgrading to 149.0 or 150.0 Beta breaks it. Reinstalling 148.2 fixes the issue.

I've just upgraded to V149 and, when using NordVPN, Firefox is now taking at least 30secs to startup. If NordVPN is off startup is instant. Prior to V149, Firefox startup was instant, both with and without NordVPN.

For over a year, my browser occasionally loses connectivity. It may work for 3 hours or 3 days, but inevitably new tabs will stop working and then slowly the others will stop as well. When this happens, none of my other browsers are impacted. They work fine. It is only Firefox. The only solution is to close everything and lose all my work.

Once I do that and restart Firefox, I receive an error message telling me I am using an older version of Firefox that is not compatible with my profile. The only solution that brings me back to the best starting place is to re-install Firefox.

My company IT spent 3 days trying to find the problem and couldn't. I have uninstalled and reinstalled so many times. All extensions are turned off, as are the two add-ons. I have been using Firefox for over a decade and prefer it to all other browsers, but I need to find a solution or I am going to have to move on. Help!!!

Hello, I am using Linux Mint on a desktop with the latest version of Firefox. Two weeks ago I could login to the Discover website with no problems. Suddenly I can not log in, but get an error message that something is wrong and I can't login. I can login using Chrome on this machine. My wife gets the same message when she tried to login to her account on my computer. After several discussions with Discover, all I get is "it is not our problem."

I am having no problems logging into other accounts with Firefox on this computer.

I have not explicitly changed anything on the browser or computer. I have done some updates which included Firefox. I can login on a different Linux computer using an older version of Firefox. Of course the updates were also to the computer and I will ask the same question to the Linux forum.

I really like Firefox and would hate to have to change to Chrome.

Thanks so much for your help.

If I type a URL incorrectly I https://www.startpage.com/do/dsearch?q=doh&cat=web&language=english displays. How can I eliminate this and just get notification that the address cannot be found?

To Firefox engineers and volunteers:

I am a native speaker of simplified Chinese, and I am currently running Firefox 149.0 for Windows desktop. There are some troubling issues and I hope to be able to fix them in the next version. Thank you very much.

The problem I encountered was that at least eight options, all in English, appeared in the browser's privacy and security settings, this has been in Simplified Chinese in previous versions of Firefox.

As a simplified Chinese user and English level of the user, I feel very inconvenient when using, I hope to get your response, thank you!

The original is simplified Chinese, I use the translator to translate into English, if there are mistakes please forgive me.
