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!

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.

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

For the past few months, I have had a problem with my computer - it seems to try to write to a hard disk (sounds like whirring ) and the keyboard freezes up for a few minutes, when whirring in the computer stops. I have taken the computer to Geek Squad two times and they said they found it, but it still happens.

I have just tried Google Chrome and Microsoft Edge and I haven't noticed it. Is this a problem with Firefox or just coincidence?

When I close the browser, recently it is leaving a lot of background processes running. As a foreground application, when I close the browser, I want it ***closed***. That is, no remaining processes/services. File|Exit should mean exactly that.

@Mozilla, please fix this, or add a very clear/obvious setting in Tools|Settings for "Close all browser processes/threads" on exit. I shouldn't need to get into about:config to start finding things to disable.

This has been interfering with backups because of files remaining open/locked even after the browser is closed.

Mozilla Firefox freezes for 5 to 6 seconds when downloading / saving files or changing the default "Save to" location.

Other programs (i.e. MS Word, MS Excel, Chrome) don't suffer from the same issue.

• I have mapped drives from my NAS on the same network.
• "Automatic Destinations" folder has been cleared
• Looking at the performance stats in Task Manager, CPU and memory usage values are normal.
• Antivirus / firewall software disabled to no affect

Here is the profiler.firefox.com report: https://www.idrive.com/idrive/sh/sh?k=a2a6j1j3o3

There is a bug which was reported 3 month ago https://bugzilla.mozilla.org/show_bug.cgi?id=1959157. It appeared out of nowhere and I don't even know if it was fixed since then. But it is bugging me a lot, no pun intended. Any help would be appreciated.

I have a Macbook Pro OS 15.6.1 and every time I shut the computer down Firefox cannot open my previous windows. I have restore previous windows checked and when I right click on the Firefox app in the dock all the previous windows are supposedly there but when I select them nothing happens. No window opens.

What is happening and how do I get my windows back?

When I have Firefox and a word document open in my mini mac the Firefox application image is suddenly pushing out or sight any word document I also have open at the same time. Conversely, when I relocate the word document and seek to open it again Firefox gets pushed out. What is going on and how do I stop it?

I am not experiencing this problem when I have Safari and a word document simultaneously opened.

Hello,

On Wednesday Windows updated in their monthly update. This update resulted in my Firefox browser losing all many capabilities in the top bar. I see the buttons for copy, download and star but can't select them. The download button works, the bookmark doesn't, the account button doesn't, the $ button doesn't, the extension button doesn't, the more features button doesn't, and the menu button doesn't.

Is this something you are aware of.... it worked previous to the download and that's the only change. I have other browsers on my computer (Explorer - No changes, Chrome - No changes) only issues with Firefox. I utilize your browser 98% of the time and would like to get this resolved.

Thanks

Whether I am on Yahoo or Facebook Firefox occasionally just stops working for a couple minutes.. Then after a while it starts working again. The stoppages seem random as they don't occur regularly. I use Malwarebytes premium to protect my computer and run scan regularly so there are no viruses etc. in my machine. Any ideas why Firefox just stops?

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.

There are three issues with YouTube: 1. Slow website performance - for example, clicking on a video to pause/start it takes a few seconds to complete. Writing comments - after pressing a key, a second passes before the letter appears. Refreshing the page is also delayed. 2. Very often, the video starts at the lowest resolution, despite being connected to a 1Gb fiber optic cable. 3. Extremely high memory usage compared to Chrome.

I have an Occasional Issue where Youtube Stutters, or lags. A good example is When I Press Pause the video will respond 5 Seconds Later. Or When I grab my mouse it will dissapear when I reach the video box. I do have You tube premium, and I do have U- Blcok origin and Malware bytes. But U- block and Bytes are disbaled on any youtube page, And I pay for Youtube Premium as well.

Firefox is running so slow since I had to get windows 11, I checked as it said somewhere for Mozilla in program files or program files 86. It is in both, but not as the browser. Should it be like that? or which do i uninstall? I'm so aggravated can't even think straight anymore
