The new Firefox 157.0 update has broken pretty much every video streaming website. I've tried YouTube, Twitch, and Amazon Prime Video. In all cases, the same thing generally happens.

Take YouTube for example. The main page itself is slow to load. And when I click on a video to play, it either fails to load or loads but has horrible stutter. When I open up the Firefox Task Manager, every YouTube page shows it's using 100% CPU.

I've enjoyed using Firefox for years, but I'll be moving on to different browser now.

I've searched other forums and I am not having any luck. If I open 1 Firefox browser then 10-15 open instances will show up under Task Manager. They load automatically. This slows down everything and I have to delete the excess browsers. Would you please offer some advice? Thank you in advance.

When my system slows down and takes forever to download, I go to task manager and find 15-20 entries for Firefox when I have only 1 or 2 pages open. Why are they continuing to pile up and slow down my machine and how do I stop it from happening?

This computer works fine with Firefox, but on my other one it opens to Sorry, we're having trouble getting your pages back. I don't want them back. But Ok, I'll go along with you. Try Start New Session: just buffers. View Previous Tabs? Can't remove the checks. Just buffers. I end up either shutting it down myself through Task Manger (no other way works) or waiting for the popup that Firefox isn't working, what do I want to do? I can't close it with the X. Restarting and shutting down then turning on the computer again didn't do any good.

I had this problem a few months ago, but not as severe. Hard booting worked, and as long as I specifically exited Firefox at the end, with the drop down menu, I could use Firefox. Now I can't use it on my other computer, which is where I prefer to work. I have to use something worse.

Not sure if this is a Firefox or YouTube bug.. it's really annoying and happens quite a few times each day I use my PC.. Is there any solution to this or perhaps reverting the update til this is resolved? I usually wait fo rit to stop lagging or if I'm not patient enough.. I'll just close Firefox entirely and re-open. Thanks.

For the last couple of days, the Firefox instance goes black and the title bar turns to an old windows look (see picture). Or turns fully blue, the color of browser theme, and the title bar is covered as well. There is no certain page that makes this bug appear, it appears randomly regardless of the page I'm visiting. Often it happens on the Firefox instance that is on the monitor I'm not working on at that moment. For example, I am browsing on my main monitor, and the 2nd monitor has a page open, the page in the 2nd monitor becomes bugged. It happens the other way too. Current Firefox version is 149.0 64 bit version, but i think it happened before the update too. I have already tried to turn hardware acceleration on and off again.

I've been using Tabliss on Firefox without any issues, but immediately after updating to Firefox 151.0, a frustrating new loading delay started happening.

Prior to the update, new tabs loaded instantly. Now, whenever I open a new tab, the page sits on a completely blank screen for about 2 seconds before the Tabliss layout, background image, and widgets finally pop in.

Because this issue did not exist at all before version 151.0, it seems like the latest browser update changed how extension-based new tabs are cached or initialized, causing a new rendering bottleneck.

Gentlemen, isn't your browser using a lot of RAM? I've been freaking out about it in recent years. That's only with 25 tabs open!! Despite the fact that the system was installed just a day ago, without any tweaks!!!

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.

When firefox is loaded and as high as 13 can load. If go to task master and search for firefox it shows 13. If I try to delete 1 file all are deleted. If I delete firefox and try to add it again it says I already have firefox loaded.

I am a user and not good at using all sort of commands etc

If my computer idles for a long period of time, Firefox doesn't recover at all. If I leave a website open, Firefox won't let me go back into it. I need to close Firefox, wait 10 seconds and open it again to open any website.

On Windows 11 laptops, I am currently using an Acer Nitro w/ 12th gen Intel i5 16GB RAM, I use my touch pad for scrolling on sites with infinite scrolling. Occasionally this function breaks, when it does it breaks for every tab in the browser window including the setting, I haven't found a singular or specific cause yet. I have troubleshooted it in the community, the prevailing logic being that themes or extensions are causing some incompatibility, so I have reset everything to defaults and made sure I have no extensions loaded, and the problem persists. I can temporarily fix the issue by going into my settings and turning hardware acceleration on and off again. I am writing this to hopefully point out this bug as clearly as possible in hopes that your programmers can fix it in a future update, as repeatedly turning a setting on and off to "fix" it might not be the best solution in the long term.

This problem is persistent and problematic.

Hi, I have 30 Firefox processes running and they are taking up ~2700 MB (84%) memory. I have 8GB installed memory. I'm running Win 11. What causes processes to run and how do I know which ones I can end?

Any help is appreciated.

Thanks, John

I've been having an issue of, whenever I tab into Firefox from a different application on my computer, the alt menu opens. Firefox seems to be interpreting me opening the program as pressing the alt key, because even when I have the menu bar set to always be open, the input immediately goes to the "File" dropdown option of the menu, just as it would if I pressed the alt key. However, I tried to troubleshoot this by 1. opening a program that tracks keyboard inputs and that didn't show such a thing happening, and 2. I checked if this issue was happening with other applications that have switch the input to the upper menu bar when the alt key is pressed, and that was not the case. This is making it a lot harder to use Firefox, as using a keyboard shortcut to open a new window (ctrl+shift+p, or ctrl+i) while in a normal Firefox tab, it will not automatically open to the new window (as it is set to do automatically), it will also not let me open the new window -- either by alt-tabbing or by clicking the new window on the windows taskbar -- and instead reopens the alt menu and sets the input to that menu, locking me to the original Firefox page unless I tab into a completely different application and then into the new window. This issue also makes me unable to input key commands or text into my active tab immediately when I reopen it, instead forcing me to close the alt menu first either or clicking somewhere on the page. And since I don't keep the alt menu visible at all times, this forces the screen to shift up and down jarringly when I'm simply trying to use the computer.

I'm using Firefox on a Windows 11 computer. I've tried refreshing Firefox and have tried my absolute best to find articles related to this issue but to no luck. Thanks for any help or advice!

I open Firefox, my browser, then I type in the site I want to open. It opens fine, however, when I try to open another site I want to open nothing happens except a little dot in front of the requested site keeps going back and forth, but nothing opens. I then have to close the browser, re-open the browser and key in the site I want. WHY? What am I doing wrong. Please keep in mind that I am not a computer savvy person and don't understand much about them. I do know however that Firefox used to work on my computer before update 150 and 151 were downloaded without a hitch. I have tried everything I could think of to fix the problem without success. I am beyond frustrated and need this fixed.

whenever i scroll trough a website in firefox, the ewperience is very laggy, feels like its 15fps. i have done basic things like disabling hardware acceleration, smooth smooth scrolling.
