This computer works fine with Firefox, but on my other one it opens to Sorry, we're having trouble getting your pages back. I don't want them back. But Ok, I'll go along with you. Try Start New Session: just buffers. View Previous Tabs? Can't remove the checks. Just buffers. I end up either shutting it down myself through Task Manger (no other way works) or waiting for the popup that Firefox isn't working, what do I want to do? I can't close it with the X. Restarting and shutting down then turning on the computer again didn't do any good.

I had this problem a few months ago, but not as severe. Hard booting worked, and as long as I specifically exited Firefox at the end, with the drop down menu, I could use Firefox. Now I can't use it on my other computer, which is where I prefer to work. I have to use something worse.

Current firefox version: 155.0

Since the last few updates, update frequency of title bar of inactive tabs slows down over time. Sometimes there is important info in title bar that should be updated frequently. Are there any flags in about:config that can be reverted to achieve that?

Firefox version: 153.0.4 / Windows 11 25H2 26200.9168

Attached are images showing the performance settings and the active extensions in case any of them proves to be responsible for the problem.

Yesterday I noticed a horizontal screen tear when scrolling down through sites like X(Twitter), YouTube, GMail, Reddit etc. I immediately checked my performance options and they were deselected. I activated them again, but this did not solve the problem, I also tried to active some layers in about:config but those were already activated. Checked Nvidia settings too, vsync is on, Edge is not affected, Chrome is not affected, even installed Waterfox to see if only Firefox-based browsers are affected, but that one was OK too.

Last resort was to refresh the Firefox installation from the uninstall utility. After the refresh and all settings/extensions got auto-reinstalled, the screen tear got fixed. I left the PC running over night and when I accessed Firefox again this morning, the screen tear problem was back. However, now, the performance options are disabled, and if I try to enable them and restart Firefox, the options get disabled again.

Would really appreciate it if anyone could provide a solution that does not involve refreshing Firefox daily.

i have checked my mouse settings and reset everything but no change,,this started after a windows update, so i went in and uninstalled the update but did not fix the problem..i don't know how better to explain it, the scroll just stopped working while trying to scroll web pages,when i try to scroll the page doesn't move ., if i move my pointer over to the right side where the indicator of where you have scrolled to is and i click under it to scroll down and sometimes it kindof goes crazy and scrolls through many,many pages instantly...i hope all this some sense to you computer gurus cause i have tried everything that i know...thanks for giving it a shot..i use firefox browser and windows 11

I've been using Tabliss on Firefox without any issues, but immediately after updating to Firefox 151.0, a frustrating new loading delay started happening.

Prior to the update, new tabs loaded instantly. Now, whenever I open a new tab, the page sits on a completely blank screen for about 2 seconds before the Tabliss layout, background image, and widgets finally pop in.

Because this issue did not exist at all before version 151.0, it seems like the latest browser update changed how extension-based new tabs are cached or initialized, causing a new rendering bottleneck.

Everything is gone from the browser today. There is no content in the menu at the top right, except for keyboard shortcuts. When I type in the search bar, nothing happens, and clicking the + to open a new tab does nothing either. My account is still showing at the top, I am signed in and the profile looks fine. I can't "refresh" the browser from the menu, as that is not an option.

UPDATE: FIXED - Today, April 13 - everything is back - I guess Firefox fixed itself.

I have a problem with 'efficiency mode' in Windows 11. Windows 11 forcefully puts many of Firefox's tasks into efficiency mode marked by green leaves within task manager in processes tab. It doesn't seem to do this to anything else except Steam Client WebHelper. My Laptop is always in max performance mode in all possible settings as it is always plugged in (this does not influence efficiency mode). It slows down performance making things take longer to load and might even break them. If you try to enable efficiency mode on a task it even warns you of this: 'Efficiency mode will lower process priority and improve power efficiency but may cause instability for certain processes. Do you want to continue?' There is no way to permanently disable it. Currently out of 19 tasks 8 are in efficiency after I woke up my laptop from sleep (I have 5 tabs open). Only way to stop it is to manually disable each one by one (right click on each task and disable efficiency mode). But Windows 11 will turn them back on automatically usually within a few seconds (it seems to depend on opening new tabs, reloading them or waking up the PC from sleep mode). From looking it up online there seems to be a way to disable it in browser on Edge and Chrome but that might be something else (I do not use the so I'm not sure). There was a solution for Chrome but it doesn't work on Firefox.

Is there any way this can be disabled permanently through Firefox or Windows 11?

Hi, I use a website called Slickdeals which has a lot of thumbnail photos showing the product on the homepage.

Firefox seems to have a problem with it where Chrome does not.

Scrolling fast throws it off...the screen turns white and I have to wait for the images to load. Also, the scrolling tends to get choppy while using my touchpad scroll.

I've tried disabling hardware acceleration, disabling smooth scrolling, and clearing cache/history.

Sometimes the cursor lags about a second from the arrow to the hand pointer on links to click.

I have fast FIOS internet and a laptop with 16 GB RAM.

Thanks!

I have a two monitor setup. Since I installed the new AMD driver (26.1.1), sometimes when I play a game on my main monitor, and watch stream on Twitch in Firefox on my second monitor, it can cause the PC to freeze completely. I hear the sound, but the image is stuck.

I tried to disable the hardware acceleration in Firefox, and it seemed like a good solution. But because of that (which is its function), sites became laggy.

Is this a Firefox, or an AMD issue? Or Windows (I'm on Windows 11 25H2)? I will try to install an older AMD driver, but honestly streams had became laggy before the driver update for me.

После включения ПК бывает, что я не могу ввести текст в браузере.(как буд-то включается режим только для чтения, что не позволяет текст ввести). горячие клавиши работают, но текст не вводиться только в браузере. Оно само по себе проходит. Как это исправить?

Every couple of minutes Firefox just freezes. YouTube buffers, all open tabs just stop working. I can open new tabs but i cannot search up anything or go into any websites. Is there any fix for this?

I have been dealing with an issue in Firefox on Windows 11 for several weeks now hoping for a fix soon but it has not come yet. When I am browsing on eBay, it will lock up and I have to identify the thread in Task Manger and kill it (just the runaway thread, not the entire program). I can then continue of eBay for a short time before it happens again. This only happens on eBay while just browsing, not bidding/buying. Is anyone else having this issue?

I run a drafting site where we share shop drawings for contractors and architects: https://usadraftsman.com

Whenever I open these drawing preview pages in Firefox, the browser gets slow or sometimes becomes unresponsive. The same pages load completely fine in Chrome, so I’m trying to understand what might be causing this only in Firefox.

Most of the previews are large drawings or viewer embeds, so maybe Firefox is struggling with rendering them. I tried clearing cache and turning off extensions, but the issue still comes back.

If anyone has dealt with similar heavy graphics or rendering issues in Firefox, what should I check or adjust? Any suggestions would be appreciated.

The lack of a title bar makes it impossible, for example, to close the application by pressing the "X" icon in the upper right corner. The title bar does not appear when the application starts, but does appear when the application window is minimized and then maximized.

I've searched other forums and I am not having any luck. If I open 1 Firefox browser then 10-15 open instances will show up under Task Manager. They load automatically. This slows down everything and I have to delete the excess browsers. Would you please offer some advice? Thank you in advance.

This started after the recent update. Any time i open more than 1 firefox window or try to move my window to a different monitor, the Menu Bar pops up and left click will be stuck only making the bar appear/disappear. I just have to close the second window because it becomes immediately unusable. I have the ui setting set to false but it still freezes new windows and doest let me click or type on anything. I've uninstalled and reinstalled, ran troubleshoot mode, got rid of extensions, reset my computer. I'm at a loss. Any help would be great
