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.

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?

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??

Hello Firefox Help Forums,

I have been struggling with a persistent issue for months now which is hard to fully describe, but simply put when I go to type in certain text boxes on websites, the input will repeat and cut random parts of the words, making it impossible to type anything coherent.

For example: "Hello world this is a test of typing on firefox" becomes: "HHelHH world this is a test of typing on firefoxello"

Backspacing to try and delete the text feels jittery as the letters take a long time to delete and can cause more garbled text to appear.

I have had this issue on multiple devices: Samsung Galaxy A54 5g, Android 16, Fennec 151.0.0 Google Pixel 6A, Android 17, iceraven-2.45.0 AND Fennec 157.0.0

I can replicate this semi reliably on the following specific sites: nekoweb.org/dashboard/editor/[page] (typing anywhere in the HTML editor) teams.cloud.microsoft (typing in the box to send a message)

If anyone has any idea on how I can fix this I would really appreciate it! Please let me know if there is any further information I can provide to help figure this out.

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 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.

The keyboard straight up doesn't show up when I tap on writable spaces. Like this support page, twitch or other chats, search boxes on Ddg or Google, or many other sites with writable boxes. Sometimes the keyboard will show up but won't actually let me write anything, and won't go away with normal means. When I try to close it, it just goes back a page and the keyboard stays on the screen not functioning. It's quite annoying and won't let me do what I want. I wrote this in a notepad app and copy paste it, 'cuz it won't let me write anything on the support page.

My phone is a ZenFone 10

On 3 different android phones, I am unable to tap on security and privacy in settings. I can tap on "set as default browser" before it and I can tap on "private browsing" after it, but I cannot tap on security and privacy. This is true of all 3 androids in the house.

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 :)
