Firefox freezes some seconds or some minute after I open the program, I end task and wait to reopen the program, opening up the program it continues to freeze. I've reset firefox multiple times, cleared cache & webdata, completly uninstalled FF and reinstalled it, doesn't solve it. Starting firefox in troubleshooting mode also freezes and hangs. After end tasking firefox multiple times it eventually stops freezing but during the next day when I open the browser the issue returns, The same goes after I reinstalled it after uninstalling it, works for the rest of the day but the next day the issue returns. Background: I switched from chrome to Firefox some months ago and imported webdata from chrome to FF.

Re: https://support.mozilla.org/en-US/questions/1600764 . TL;DR, encountered this exact loading issue of firefox responding and after using a profile blamed it on a patience issue. I assumed so because my longest hang time would end up being ten minutes, which was the first time, never got past 5 minutes afterwards. Fast forward to now, it has been a few weeks since I used my pc due to general life business, so I had to turn it on, firefox opens, hang takes FIFTY MINUTES. I have also had to restart firefox several times due to missing updates and each and every hang time has taken a MINIMUM half an hour, and this is before giving up and closing the window on many instances. I have been sat here trying to do anything in firefox for over five hours now. The ONLY excuse that I can make up is the main reason I'm at my pc is because it needs updates and is currently downloading updates, so that is using a lot of my disc (I'm on an HDD if that's important), however it shouldn't take nearly an HOUR to use firefox for like a minute and then take ANOTHER hour simply due to hang time. I have also checked task manager and Firefox is using very little cpu (0%-2% at most) and not a lot of ram (initial hangs were down to ~50 mb, now it's around 300). The only thing I can think of is that the issue could be with the history file being corrupted, but since I have that synced with a mobile device, i don't know what that would do, nor do I want to lose my history, but otherwise i am at a loss and need more advice.

Firefox's performance keeps getting worse. I have to clear the startup cache several times a day just to get any sort of decent performance! Reinstalling hasn't helped, and disabling add-ons hasn't provided a solution either. Has anyone else experienced this, and/or does anyone have a solution to the problem?

As soon as I signed into the browser to sync my account, this issue began. I have deleted profile locks, started new profiles, opened in troubleshooting mode, fully reinstalled, and the issue continued (even before signing back in). I am out of troubleshooting steps and would like to avoid blowing my VM away if at all possible. Someone please help!

I started noticing that Firefox was giving me a lot of "not responding" freezes the past couple of weeks. The past couple of days I basically cannot access Firefox at all - constant, immediate freezing. I have tried uninstalling/reinstalling (multiple times), disabling hardware acceleration, running troubleshooter mode (still freezes! if it opens at all!), deleting profiles, restarting my computer, etc. I've done just about everything I can find online about this issue. Nothing has worked. I have no issues with Chrome or Edge.

Any suggestions??

I am having issues making the menu bar reappear after I enter full screen and I am using only the touchscreen on my laptop I can't get it to reappear I have to tap the screen like crazy, when in the past I could just slide down and it just worked it.

This morning, I can no longer download (Save) files to my computer, nor check/change settings in Firefox. Tried all troubleshooting steps to no avail.

If I delete and reinstall Firefox, will I lose all my Bookmarks, etc.? Running version 157.0 (aarch64).

Appreciate any help!

Well I am continuing and repeating my question placed in August 2026, where I found that Firefox V154.x stalled in an erratic way that made it completely impossible to use it or to send a crash report. So your suggestion to send a crash report was not very bright or helpful. I deliberately omitted the subsequent updates, to try again after a main version update. Alas, we have the same situation again in V157.0, this time more predictible. The program stalls immediately after trying to open another tab. And again, you can kill the program only by task manager.

The additional question I have, is how to switch off the annoying update message, as long as Firefox is dysfunctional after an update, I'd like to avoid any update under all circumstances. I have to work with Firefox, so it is more than an leisure thing for me, I cannot afford to cripple Firefox by an unintended update.

I had to reinstall the last known working version (153.03) to send this message.

When I watch YouTube videos, Firefox behaves strangely. After a few minutes of watching, I try to scroll to the comments, and then Firefox starts to lag. Scrolling becomes very sluggish, and the entire image freezes while scrolling. The website stops responding, but the sound continues. The only way to fix this is to minimize and then maximize Firefox. Then I can scroll again and the problem starts again. This problem occurs regardless of whether I clear the cache, use an ad blocker, or which screen I'm using Firefox on. Sometimes, one of my screens even freezes and displays stripes. However, this only happens when I'm using Firefox and YouTube. I have no problems with any other applications for exampmple playing games on one screen and let music streaming app playing on the other screen. Even my Cubase 15 work like sweet on booth screens without errors. Why is firefox acting so strange? Firefox never completly stops or closed itself.

Firefox Version 157.0 (64-bit). AMD Software: Adrenalin Edition 26.8.1. Windows 11, version 26H2 installed October 1, 2026 (previous updates also had the same issue with firefox).

I also got some Firefox Updates when i opened it. I was hoping they catched the issue but it seems like the same.

Have a great day :)

Preferred Firefox for most of my online use in my 82-year career in the ICT space - why has it deteriorated so badly? Am using Chrome for now, works perfectly, doses not freeze up my browsing or simultaneous use like Word or outlook. Should I abandon Firefox and switch to Chrome permanently?
