Hello! Today I stuck with problem in my system: after minor package update, hardware acceleration was broke. In past, I stuck with same problem after total pc upgrade (AMD -> NVIDIA GPU, another might be unnecesary), and somehow I fixed it, but i dont remember what exactly fixed it. Can someone please help me turn hardware acceleration on this time? My searching the key arround didn`t helped, but i found in about:support line which notes that firefox unrecognized my videocard etc. My specs: kernel: 6.17.1-zen1-1-zen driver: nvidia-dkms-580.95.05-1 videocard: GTX 1080 TI DE: gnome 49 with Wayland

Steps that i have tried: Tried to make all as wrote in archwiki Tried to install an nvidia vaapi implementor Made some random steps from internet, without effect(maybe thats why hardware acceleration doesent work??)

theres also about:support page attached

Running Firefox 140.3.1 ESR on Debian, lately I've been experiencing a bug when I have several instances of Firefox open, and multiple tabs open in each instance. After a few minutes of browsing and opening and closing tabs, I am unable to drag tabs to rearrange them (above the address bar). The "X" that is part of the tab also doesn't work to close the tab, and clicking the main "hamburger" menu icon (three horizontal lines) does not drop down the menu. If I switch to a different instance of Firefox that is already running, sometimes the "hamburger" menu icon starts working (sometimes not), and I am able to exit and restart Firefox, which works for awhile, and then a few minutes later the same thing happens again. Interestingly, when it's not working, I am still able to "right-click" on the tab and choose "close tab" from the drop-down menu.

I've been trying to discern a pattern, but have not been able to find a way to reliably reproduce the error. It often seems to happen when I'm using Reddit or Craigslist (maybe only more noticable because I often open and close a lot of tabs on those two sites). At one point I thought it might be related to opening a new tab for a site that had previously been opened in another Firefox window (instance), but that may be a false lead, because I haven't been able to find a way to consistently trigger the bug.

Thank you for maintaining the best privacy-respecting browser in the world, an indispensable tool for me.

Firefox not responding on macbook M4 Macos Tahoe 26.0 I tried restarting Firefox I tried restarting my macbook But everything repeats. Use Firefox for a while and it freezes again. Tôi sử dụng Firefox mới nhất: 143.0.1

Firefox freezes when I try to sign into YouTube via Google. Becomes totally unresponsive and I have to close browser. It's the only site this happens on. I have cleared the cache and cookies, unchecked "Hardware Acceleration" and other recommendations from other posts. Please talk to me like I'm your Baby Boomer dad.

I've seen on this forum from April that people are having an issue with Firefox and Google Passkey. I'm trying to log into my gmail accounts and can't get passkey to work. It freezes the browser and I'm not sure why this hasn't been resolved. Mac updated to Tahoe recently and I was on Sequoia 15.7.x (not sure exactly. Still froze. Photos are to show what's happening and that I needed to Force Quit each time.

As per the topic, since the MacOS 26.0.1 update Firefox freezes after resuming from sleep. Specifically, tab selection, page refreshes or menu selections cannot occur. Keyboard command to quit does work and after a reload all tabs, windows and function is restored

None of my extensions have changed and for the first week or so after the initial MacOS 26 release this issue wasn't occurring. No other application or system changes have occurred since 26.0.1.

При заходе на сайте ya.ru и если на нём имеется строка с видео или поиск с алисой, то начинаются сильные фризы. Это ошибка именно в firefox 142, проверенно.

I've uninstalled every profile and installation of firefox. All addons are gone.

Upon reinstalling regular firefox, doing refresh, and syncing my account, the browser immediately freezes.

This issue has started within the past week. I've not done any major changes to my computer or firefox in general. Edge browser does not have this issue.

about:processes also freezes, making troubleshooting difficult.

I'm currently running firefox without syncing at the moment, but this isn't an ideal long term solution.

Is there a way to have Firefox start with all, or all but the first tab unloaded?

My Firefox starts with about 100 tabs open and many of these now have ads running which makes Firefox very slow. It seems to take ages and ages for all the tabs to load.

Maybe if all the tabs were unloaded when I start Firefox it would be quicker to get up and running??

I'm running Windows 11 on a desktop with an i5 CPU and 32 GB of RAM.

Any help much appreciated.

Hi, I’ve noticed that Firefox often uses a lot of memory when I have multiple tabs open, even more than Chrome or Edge on the same number of tabs. Sometimes it slows down my system or makes switching between tabs laggy.

Is this normal behavior, or is there a way to reduce Firefox’s RAM usage without losing performance? Are there specific settings, add-ons, or troubleshooting steps I should try?

Thanks in advance!

I use both Firefox and Google Chrome. My mouse works fine with Chrome but with Firefox there are frequent long delays (60-120 sec.) when moving from one web site to another. The mouse just freezes up and I have to struggle to close Firefox. No problem with the mouse with Chrome, but I prefer Firefox and its features. Any suggestions?

I opened Firefox on one of my computers as usual today but the whole performance changed. Used to go to my home tab and select various news sites to see what was happening. First, when I scroll down the bookmarks, I would hit the "news" and click on it so all the sub items would stay in the scroll, but instead of that, it wanted to open every item as a new tab. When I finally started opening the various news outlets, it opened them in new tabs, it had always opened in the same tab. Then, I couldn't close the various tabs it had opened. I would go to the tab and hit the "X" but it didn't close the tab. I had to use a drop down menu to close a tab. And when in a site, I used the scroll button on the mouse, instead of scrolling, it made the page larger or smaller instead of going up or down. What could make such a change in behavior? I opened up the 'settings' on it and looked at 'tabs' and they were the same as the ones that are on this computer that works as expected. Both computers have it set to open all previous windows and tabs. Both have the same settings for 'tabs' and 'browsing'. I don't get it. Both are version 143.0.3 (64-bit) I have Ubuntu OS.

Macbook Pro using Tahoe 26.0.1; desktop freezes when Firefox 140.3 is active. Desktop icons do not work. Firefox has to be shutdown for the desktop icons to work.

Initial performance is good, but over time especially when tabs are opened and closed frequently responsiveness to user input (e.g. tab switching, opening/closing tabs, response to hyperlinks) becomes very slow. After force quitting and restarting, performance is good again for some time. I exclusively use private tabs.
