I've been using Firefox for a while, and while there are many things I like about it, it has always been a resource hog. In the past I could get around this by just killing Firefox in Windows Resource Manager and restarting, but ever since getting a new computer an upgrading to Windows 11, it's gotten worse. Every couple of days my computer freezes for 10 or more minutes, I'm having to do a hard reboot ever few days, and I'm even bluescreening about twice a month. I'm pretty sure Firefox is the culprit because killing it will usually resolve the issue.

I'm wondering if there is some way to put Firefox in a sandbox so it does not consume nearly all available memory and other computer resources. It is by far the biggest consumer of resources on my system and I do not want to dedicate 4GB+ of memory to an app that is just showing a couple of web pages and playing YouTube videos.

I've used Firefox for 20 years through the various iterations of Windows, and have been using it trouble free on Windows 11 since November 2024. Two days ago, however, When I tried to open the Guardian site (www.theguardian.com) it would open very slowly and not load and of the pictures. This gradually got worse, the site taking for ever to open at all, and always with the little dot in the tab at the top left going from side to side showing it was still loading. I have tried everything I can think of. Opened in troubleshoot mode, changed DNS settings, uninstalled and reinstalled Firefox twice (one time to see if it would work normally if I didn't actually sign in to my account). All to no avail. In fact now things are worse, in that the GOV.Uk website is now giving me similar problems - and a few other sites have become slightly slow and reluctant to open as well. My internet connection seems fine, and all these sites open without any trouble on Microsoft Edge. I am NOT very good at tech, and I am now tearing my heair out as to what I can try next.

Any help wopuld be gratefully received!

The system asks me to sign in using my passkey or to try another way. The screen is frozen - can't enter passkey, can't choose another way. The only way out is to close firefox. I have no problem signing in with a different browser (Safari).

What is apparently the official Firefox policy is incredibly dumb:

They provide users with that ability to add secondary email addresses, recovery codes, and authentification, BUT they REQUIRE access to the primary email address to make the secondary email address primary.

IF the primary email address is unavailable, the secondary email addresses, recovery codes, and authentification are completely useless for making the secondary email address the primary one.

This supposedly provides "enhanced security".

Pro Tip: If you deny ALL internet access, you will be very secure on the internet.

Not very useful, but..

Genuinely astonished that Firefox Support thinks this is not insane.

The entire window of Firefox has an abnormally low resolution, makes the entire browser seems blurred. This issue occurs after I upgrade firefox to 146.0. I've attached a screenshot, and you can see the Firefox window has lower resolution than the wallpaper and task bar.

When trying to access windinfo.eu, I get the message "you are not allowed to preview snippets". Other websites work o.k. I had used the snipping tool on a different website, but not on this one. The problem persists even after deinstalling the snipping tool and restarting. On edge, I get access to windinfo.eu.

Many thanks in advance for your help

Running version 146.0.1 No new extensions. Recently, when I hit ctrl+b to bring up the bookmarks sidebar, it opens but doesn't display the bookmark correctly. (image #1) The sidebar opens, but everything is whited out. The same thing happens when I try to open the history sidebar, except that the urls kind of show up. (image #2). Also, when I'm on my homepage, there's a white line on the left side that I can't get rid off. (image #3) I also tried refreshing firefox, but that didn't do anything. Does anyone have an idea what may be causing this? Thanks

Please dont turn firefox into AI slop. The browser does not need "AI" shoved into it and currently the lackthereof is one of the only things keeping a large user base with firefox. Please please don't cram more AI down our throats. Again, no one wants this shit except MBAs.

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

146.0 (64-bit) Windows 11 December 11, 2025 Turned on computer this am, Firefox webpage popped up telling me about what is in it's future but now my side bar is black print on really dark background. Help!

Hmm. We’re having trouble finding that site.

We can’t connect to the server at fzttlwrt.r.us-east-1.awstrack.me.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

Some of the installations seem to be blocked by Microsoft if you are using a Microsoft system. If the Software being downloaded is not sold by Microsoft store, Microsoft blocks it or deforms it. During any update, Microsoft removes MusicBee and some other software not purchased from Microsoft store

Emojis do not show on Firefox 146 on macOS. I downgraded to 145.0.2 and they do show, so it seems related to Firefox 146.

I have macOS 26.2 running in both test cases.
