Hi!

I don't understand. Firefox is eating up memory again in the latest versions, and on top of that, it's the GPU on my PC.

4GB for the app and up to 8GB.

Are you mining Bitcoin on my machine?

What are you doing?

I had 128.7 esr installed and was getting crashes and upgraded to 128.8 esr and it was worse. Down graded to 128.0 esr and it seems to be working just fine so I will not be doing any further upgrades.

I restarted Firefox on my Mac earlier, which I think updated it from 136 to 137. After reopening it, web pages won’t load anymore. They either time out or just load indefinitely without doing anything. I went through the troubleshooting page and tried reinstalling it, which didn’t help. My computer’s firewall is off as well. I’ve tried refreshing it multiple times, and I get a message that Firefox has crashed before it actually refreshes. After that, pages will load normally for a very short amount of time (about 30 seconds) before stopping again. Pages are still loading normally on Chrome and Safari, so it’s only Firefox that’s having an issue. Does anyone have any solutions for what this could be/ways to fix it?

before v151.0.2, didn't have a problem with firefox, now with this new release, it is really really slow, takes some time to start and load pages. what happened??

I have observed that firefox has a coloring problem. When firefox is minimized to the toolbar, after a while, maybe a few minutes, when it is opened, there is always black uncolored content at the bottom of the screen, occupying about 1/3 of the height.

Attached are two screenshots.

Despite being listed as supported on: https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/enumerateDevices

enumerateDevices() still only returns input devices. Running navigator.mediaDevices.enumerateDevices().then(devices => console.log(devices)); in the Firefox console only shows input devices while on Chrome it shows output devices.

I use a website that supports playing from multiple output devices so when receiving a phone call, your desktop speakers and your headset can ring at the same time. This works in Chrome but it doesn't in Firefox.

I'm running Win11, v25H2, os 26200.8524 on a Dell laptop. Firefox v151.0.3 (64-bit) is behaving a bit odd in that I can open a window, open maybe 2 or 3 tabs, close all but one down, and if I check Task Manager it'll show multiple Firefox apps open, sometimes as many as 20+, and the disk usage/storage is usually between 750MB and 1.2GB. I can see if I had multiple windows or tabs open that the number of apps in Task Mgr would be equal, but if I've only got one or two tabs open and Task Mgr shows I've got 23 open? I have gone into Firefox/Settings/Privacy and Security and selected "Never Remember History" so that if I click on History in the main menu bar it never asks me if I want to clear history, but it will show "Recently Closed Tabs" for whatever tabs I may have opened during that Firefox session. But again, if it shows I have 4 recently opened tabs, why would Task Mgr be showing 18 (for example) open instances?

I have not activated Firefox VPN, I have Enhanced Tracking Protection set to "Standard", I do not have A-I turned on, I don't usually use Private Windows, and I don't have any 'extensions' or 'add-ons' installed - I'm using pretty much the 'standard' Firefox installation. I have Norton 360 VPN installed but rarely turn it on. If this makes any difference, I did try out Privacy Badger about 3 months ago for about 2-3 weeks, but it got so odd that I uninstalled it. Interestingly/oddly enough, about half the websites I visit multiple times a week still give me a pop-up message saying "We see that you're using an ad-blocker, would you like to turn it off?" but I can't turn it off if there's nothing installed. To see if I could stop this 'phantom ad-blocker' I even went so far as to "refresh Firefox", but actually I'm getting more instances of websites telling me "turn off ad-blocker so we can make some money out of you!!!" since the refresh.

This is annoying, not life-threatening but since I've had other problems with low disk storage/ high usage, I try to keep an eye on it and Firefox using ~1GB of space doesn't help the situation. I had asked about Privacy Badger a couple weeks ago and the answer was pretty much "if it's uninstalled, it's not working"... so that was pretty much a dead end.

Ideas?

Hello !

I recently got a new laptop (Lenovo Legion 5 I think) and while it's been working great, I've noticed a glitch that's happened a few times now. It's usually preceded by the image having some weird line pattern, I haven't been able to take a picture of it but it's almost like the pixels have been shifted ever so slightly. After that the screen sometimes splits strangely (see image). I don't know if this is a hardware problem or a Firefox thing but the only time it has happened was when I was on Firefox so yeah...

firefox stalls on ubuntu and the OS says it is running but I cannot or don't know how to restart/reset it from the terminal. A reboot of the computer solves the issue but I have to re enter the bios password etc. Is there a simple solution?

When I open Firefox it opens a maximized window with tabs, then it opens a minimized with a single tab, then it reopens a maximized window with all session tabs. Each window displays in succession, one window at a time.

I'm on desktop using Windows 11.

I just read a post saying this behavior was caused by the resist fingerprinting feature. Can someone explain how that causes the repeated opening of browser window 3 times. Is there a way to retain the anti-fingerprinting behavior w/o the multiple window opening behavior?

Hello!

I would be very grateful if you could help me figure it out, the browser suddenly stopped working, does not open any tabs, just a blank screen, does not open settings, some buttons simply do not respond at all. I cleaned the SScleaner yesterday, but I did not select anything special there, it was a basic regular cleaning that the program offers.

How do I fix this? reinstalling does not help, the browser still does not work

For the last day I've been having a problem with FF slow to load. I've tried the troubleshoot mode with little change. When it does load I can have problems with certain web sites loading e.g. Youtube, MSNBC, AOL mail etc. It's never consistent. The cache is clean and I've saved all the relevant cookies, I checked my internet provider and they are having no problems and I don't seem to be having any internal hdw issues e.g. ethernet cable connections etc. I reinstalled FF-not a clean install and seemed to help for a time. Do I have any options other than a refresh? I don't seem to be having the same issues with Edge or Chrome. All W11 updates are current. I look forward to anyone's comments.

Subject: Assistance Required for Frequent Firefox Crashes on Ubuntu

Dear Developer Team,

I am facing persistent issues with Firefox crashing on my Ubuntu PC, and the problem has been ongoing for the past 40–50 days. Despite multiple attempts at troubleshooting—including uninstalling and reinstalling Firefox, clearing all caches, and other measures—the issue remains unresolved.

I’ve noticed that Firefox works for a few days after reinstallation, but then problems begin to surface, such as a half-screen display. Eventually, after restarting the PC, the browser starts crashing again.

Could you please investigate this matter urgently and provide a resolution? Additionally, I would appreciate it if you could clarify whether this might be related to a RAM issue or some other underlying cause.

Looking forward to your assistance.

Best regards, zimmi

Every 1 - 2 hours Firefox stops loading pages and I have to shut it down and restart it and restarting takes around 6 clicks on the icon to get it to start.

Also one time today I lost all my pinned tabs and had to manually restore them one at a time.

Using Ubuntu 24.04.2 and latest Firefox. Cleared cache but doesn't help.

AMD ReLive instant replay does not work if mozilla firefox is open in the background while playing a game. It works fine with Google Chrome running in the background, closing firefox "fixes" the issue.
