Hi, after latest update just now, the browsers uses up to 45gb of ram within a few minutes! Not sure what it is, I am on MACOS Sequia Version 15.6.1 (24G90) macbook pro M1

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.

After I disabled ws2ifsl in the Registry Editor, problems began to occur when launching Firefox: as soon as I clicked the mouse after starting Firefox, it would become unresponsive. Even re-enabling ws2ifsl or refreshing Firefox was of no avail. No matter what I did, it would enter a completely unresponsive state as soon as I clicked the mouse. Do I really have to reinstall Firefox? Note: This is for the Windows version.

Hello,

After recent macOS updates, it appears that Firefox would get stuck when trying to access passkeys stored in macOS's passwords or keychain apps. I run into this issue with both the following two combinations of Firefox versions and macOS

144.0.2 on macOS 26.0 Tahoe

140.4.0esr (aarch64) on macOS 15.7 Sequoia

Any insight is appreciated!

I'm running Firefox 144.0.2 (64-bit) on a Mac using Sequoia 15.4.1 OS.

At the most recent Firefox update, I added VPN.

Since then, I've had a problem with Firefox hanging. Not immediately but after varying amounts of time, 20-60 minutes. I get an "Out of Application Memory" pop-up but the usage for both Firefox and other elements are well within normal range, not high. It's completely frozen and the only way out is to do a Force Quit.

There are times when doing a shut down I notice that VPN has somehow been turned Off and once I saw a message of Background Service Error attached to it.

Having to constantly re-start Firefox is a major pain. Oh-- I did turn off the background AI thing under Tabs. I hate AI and try to turn it off everywhere I find it. A resource suck and bad for the planet.

Any help appreciated.

Windows updates from Oct 14 have messed up both firefox and an extension (Ironvest). Can't access mozilla account from icon on toolbar (just a revolving blue buffering circle), nor will the extension work. Have uninstalled extension, turned off/on computer, reinstalled, no luck. Discovered the mozilla account won't work after this, so resigned in a couple times, still the same issue. Even uninstalled one of the window updates (performance, not security) and still not luck. I hate windows when they update and upset all my settings.

I had two Firefox windows on my computer, one with a few tabs of Youtube and Twitch pages, and a private window with a single Twitch stream. I've had them and the program open for days, with my conputer turned on and off multiple times with no issues.

Today I booted a game I installed yesterday on my computer and played for a few hours, after closing the game, both my Firefox windows became completely inaccessible.

I've tried closing firefox, restarting my computer, letting Firefox create a new xulstore file and nothing has worked. I can't see the window, I can't make it active. It's permanently minimised.

It spikes Desktops Windows Manager to 100% GPU usage, it makes my PC lag and run slow, and I can't do anything in the browser cause the window won't stay open or up. I can't even open the old window and then a new one, it stays minimised and I can only see the preview by hovering my mouse over it.

I've tried GPU driver updates, I tried anti virus scanning, and I've tried opening another browser which did work. But Firefox is the one with all my saved settings and preferred browser. I also can't see the Firefox window at all when using the window key + TAB to check my desktop, but it does show up on Task Manager as running.

Please help me restore my program. I'm making this on my phones firefox browser which is running fine

This started happening a few days ago.

I tried to drag a tab out of the main window to put it in its own window on my other monitor, but the tab just became unselectable, and if i scrolled in the tab bar, the tab icon and text would remain locked in place in the display while the other tabs moved behind it.

The main Firefox window also lost the minimize, restore, and close buttons. The only way to make the tabs work was to close Firefox and relaunch it.

I noticed this happened only after any app in the OS went full screen, be it a steam game, or another Firefox window, or a VLC window, or anything else that I did that made an app full screen in any of my monitors.

I am using Ubuntu 24.04 with KDE Plasma 5.27.12. Kernel is 6.14.0-29. Display server is Wayland.

Initially I thought this could be a problem with the snap version of Firefox, so now I've installed the deb package, but the problem remains. Firefox is the only app which presents a problem of any kind when any window goes full screen.

Here's a video showing what the problem looks like, in case my description was not clear. The ghostly tab in this video is the chess.com home page and you can see it as the third tab from the top right of the video, and it remains in that position as i scroll the other tabs, completely unselectable with the mouse.

Any idea of what could be causing this issue to appear?

Thank you!

Since a month or so, Firefox browser freezes when playing youtube videos. Simply closing the app and restarting won't do the trick, I am forced to open the WIN Task Manager and manually "end task" before I can watch youtube videos again ... until an hour later, or lucky a day later, the same drama unfolds. I run the newest version of each, Firefox and Windows 11. No new extensions or plugins have been added recently. What is to do here? I'm since Netscape on this route and would hate to switch to another browser... :-) Thanks in advance!

I have Firefox (always updated to the latest version) and I have noticed a memory leak that EATS up RAM. I have 1 tab open, playing a set spotify playlist. within 24 hours of rebooting the machine, Firefox has swallowed 7gb of my Memory as shown in Activity Monitor/Memory Pressure. I've been having this issue for some time, updates to MACos make no difference either. NO other program does this. I've tested the same playlist in other browsers, Chrome, Safari, uses 1gb, brave/opera uses less than 500mb and they've been open for over a week. This memory leak is a bug in Firefox. I've seen it before (other software, mainly on Windows) but never like this on a Mac......How do I escalate this?

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.

Upgraded my Mac to Apple OS TAHOE 26.0.1 and upgraded to Firefox 144.0.2 (aarch 64). Upon opening Firefox, the application hogs my computer's 8 GB memory, taking 6.3-7.9 gigs (!!!) with only one tab opened! When I try to browse and use it, it often freezes and for the first time in using MACs for 40 years I got a warning for excessive memory usage and prompt to force quit other apps. Firefox in this version is practically unusable (unless I get 16 gigs of memory!) I think guys that this version uses an excessive amount of resources, needs serious "diet" and compacting. Please fix our favorite browser in a trimmer new version. Or after 30 years nearly I (and many others with * gig machines) will have to switch default browser, not my favorite solution for sure

Having an issue that happeened after updating to Sequoia 15.7.2, when launching Firefox, it opens a new tab, but nothing loads.

Profiles don't load, I'm unable to search anything, unable to even pull up settings.

Have tried reinstalling, clearing NVRAM, deleting profiles in finder.

Hello,

In the DevToolbox, the “Copy all as HAR” and “Create file...” functions are not working. It seems that in both cases, only empty space is placed in the clipboard and in the file (this has been happening since the last update).

Thank you in advance.

My internet browsing gradually gets slower over time. By the end of a day or a couple of days, it is unusable. The problem isn't bandwidth. A speed test shows that throughput is absolutely normal. It's the browser response to navigation. ie clicking a link, typing a URL into address bar, etc. and having to wait minutes for the page to start loading.

If I quit the browser and re-open, everything goes back to normal.

Any ideas what might be the problem?

A couple days ago, some weird issues have started:

• All my bookmarks are gone
• Any of the buttons in the UI that open a smaller UI do not work (such as the 3 bar menu)
• Similarly, right clicking to open a menu (such as "Save Image") also does not work
• Any dropdown menus in websites seem to also not work. For example, in this very support page, I could not select an option in the "Which topic best describes your question?".

I can't restart and troubleshoot Firefox since I can't access the 3 bar menu.
