Firefox: форум сообщества

On updating to linux mint 22.3 - cannot type anything in firefox in address box, search and primary password or anywhere else within firefox - have uninstalled & reinstalled but nothing happens

Nothing is working after updating to the latest patch.

NOTHING.

I cant open a new tab from any links at all. I cant copy an paste inside the browser AT ALL. My cursur looks like its about 25px off true. please roll this patch back ...why do they continue to allow engineers or coders to break it when it works fine?

Hi,

I use FF 146.0.1 64-bit on MacOs Sonoma.

I experience this weird FF behaviour. I usually keep FF open all the time. After a while, days, maybe weeks, some UI elements start flashing when I hover the mouse above them. As an example, I use the whatsapp web UI. When this happens, I cannot click anymore on the emoji icon (on the right side of the message) to add an emoji icon to a message because that icon is flashing like crazy when I hover the mouse above it, and when I click the mouse I cannot hit it. Refreshing the page doesn't fix it. What I usually do is I restart the browser and then it gets its brains back.

I am just curious if any of you experienced this. It starts to become annoying.

Thanks

Environment:

  Windows 11 Pro, Version 25H2, Updated windows (include KB5074109) on Jan 16, 2026.
  Firefox version 107.0  

Issue:

  Firefox freeze shortly (e.g. after play YouTube video for less than a couple minutes, just browser YouTube videos for a while, or just open about:preferences page).
  
  I installed  Firefox 147.0.1. Same issue. 

  Hover cursor to Firefox, it becomes busy (blue spinner)

  Note: Firefox works fine before the windows update. Chrome exits suddenly after the update too.

Task Manager: shows 15 FireFox processors with 0% CPU usage.

When I first open Firefox I have noticed the past few days that if I try to click on anything on the menu bar right away I get a not responding error message and I have to end up shutting the program down. If I wait a few minutes the menu bar does work normally.

I am having trouble downloading documents. They never finish loading and if they do I cannot download them to a file. Also when I exit firefox it isn't closing correctly. It brings up the last session. It keeps telling me it is still running even though I am exiting.

I get screen tearing on videos or when i scroll on any website. Only happens on Firefox, I've tested Chrome, Edge, Opera.

Smooth Scrolling is Off. Hardware Acceleration is Off. I've tried toggling "gfx.font_rendering.directwrite.force-enabled" Firefox is up to date.

None of this has helped.

When I brought Firefox up about a week ago, it presented me with a survey, results of which were sent to Firefox developers. They asked several multiple choice questions about features, but they didn't ask a very important question: Would you use Firefox more if it used less system memory? I currently use Google Chrome for about 2/3 of my web browsing because Firefox uses up too much system memory. I would prefer to use Firefox most of the time, but can't, since it bogs down when memory usage gets too high.

The survey should have included a text input box so users could enter any comments for the developers, and the survey did NOT do that.

So, after completing the survey, I was disappointed that I couldn't comment on the most important issue I have with Firefox. I would like the Firefox dev team to try get Firefox's use of system memory down. A short while ago, I opened 4 websites in Google Chrome, then opened the exact same 4 websites in Firefox. The attached shows the memory usage of each browser.

I have 5 windows open in Firefox, yet only 1 of them is visible/accessible on the Windows Taskbar.

I know there are 5 windows open as Troubleshooting Information reports "Multiprocess Windows: 5/5"

Sometimes when I launch Firefox, the other 4 windows will be visible, and this current one will disappear. If I go to Recently Closed Windows and open that window, it will appear, but the other 4 will be hidden again.

Other times, I will launch Firefox and one window will be invisible, and it won't appear unless I close all the other windows, then it will suddenly appear out of nowhere.

I've been using Fire Fox for decades, but lately it is so slow, I thought there was something wrong with my Windows 7 ultimate. I've done full Windows reboot, to no avail. Then I see the internet t hat FireFox is starting to implement AI. I thought that may be the issue, but after looking into it, looks like that isn't an option with my old Win 7 OS. So if that isn't the problem, how can I find out what is bogging Fire Fox down? I keep a watch on my CPU usage, and the usage is going nearly to 100%, when it used to barely go over 10%. When I check the actual CPU usage, it shows as many as 15 or more items tied to Fire Fox.

Is this all a result of continued use of Win 7? I'm planning to move to Linux, but that will take me some serious time and effort. Gerald

I've disabled extensions, changed settings, and reinstalled multiple times, but Firefox won't quit stuttering constantly. Other browsers work fine on my computer, and Firefox doesn't seem to be using much memory.

OS: Linux Recently, firefox has been annoying me with not closing a tab when I click the X like normal. I have to right click and close it, or press ctrl w. I am unable to move tabs around, as well. I am not sure since when this next bit has been happening, but I am also unable to interact with many elements of the top bar. The only thing of the firefox ui besides the websites themselves that let me interact with them at the moment is the home button, the new tab button, bookmarked sites, and that box icon on the left corner that lets you look at previously closed tabs. My Firefox's version should around, I believe it is 140.5.0 ESR. Thank you in advance. Update: Upon a restart of firefox, it appears to be working again as normal.. However, the bit with tabs not closing when the X is clicked and not being able to move tabs around has been happening multiple previous times, and it may come back. Update again: The issue does come back after some usage. I'm using KDE plasma with Wayland. I will try what the answer asked, and come back later. Update: This seems to happen very randomly and is not reproducible for me.. It will go a few days being fine, then randomly freeze again. Has not happened under another user, at least not yet.

Firefox has been using more RAM and CPU on my system recently, especially with only a few tabs open. Is this expected behavior, or are there specific settings, extensions, or configurations I should check to improve performance?
