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.

Hello, For about two or three days now, when I launch Firefox and try to open any website, it takes maybe one minute to load the page, then the navigation is OK on every website.

It only happens when I launch Firefox for the first time of my session. If I close it then relaunch it, it's still very swift.

I tried clear cache and remove cookies, just lost my logins lol but didn't work. I also tried with no extensions, nothing changed. Lastly I tried to set "network.captive-portal-service.enabled" to "false" in "about:config" but it didn't change anything neither.

So before I try anything else that could erase something on my profile, I'd rather ask here for some help :)

PS: running FF 153.0.4 on Debian Trixie with Mozilla repos. Only have two extensions: µblockOrigin and NoScript.

Thank you in advance!

Hi everyone,

Since updating to Firefox 129 on Windows 11, some tabs become unresponsive after my laptop wakes from sleep — no crash, no "Not Responding" warning, just frozen. about:processes shows the tab still running with ~0% CPU, so it's not hung, just not repainting.

Tried: disabling hardware acceleration (helps a bit), fresh profile (still happens), Troubleshoot Mode (less frequent but not gone).

Anyone else seeing this? Known WebRender/compositor bug tied to sleep/resume, or a Windows 11 power management conflict?

Thanks!

Hi Team,

In Firefox, the close button is only partially clickable and is not accessible on the right side. However, when I hover over it, a square background appears around the button. Could you please take a look?

Thank you

Every thing will be working fine? And then I click on something, and it takes a long time. And then at the top of my prompt, it says Mozilla firefox is not responding. I've been dealing with this for some time now. You can't figure it out. This is happening on my computer. Also I would update it the program and the very next day.There's a prompt asking me to upload again. I upgrade, and then I still get the same thing.Mazilla is not responding.

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'm having an issue where when you try to do things in-browser, Firefox freezes, puts up a grey screen and holds this way for a few seconds. Scrolling and video seem to trigger it most often. Repeatability is nominal; sometimes I have no problem, sometimes every action I try to take results in another fit of grey screens and freezing.

I'm using version 153.0.3 64bit on Windows 10.

I have Firefox 152.3 (73911) on iPhone with the latest iOS 26.5.2 On Firefox, web pages not showing up when switched between open apps on iPhone.

I can see web pages on Safari.

Hello Im using multiple firefox edition on my PC from beta dev to nightly, and recently in nightly and only nightly I've spotted strange issue that appears as window in window screenshot attached, outer x to close or maximize window does not work only the inner and mostly goes after F11 full screen and then return to normal. Troubleshoot mode and restart does not change or fix this.

For years now... It's crippling, every time I leave the Firefox browser... It refreshes when I return.

5,000 times in the last two years since I got my Motorola play 2023 phone... I try to login to a site and have to click on messages to get a code and the browser refreshes and I have to start over.

1,000 hours of nonsense you have caused me. I couldn't get food stamps or Medicaid because of your bullshit

It's called persistent Internet you fucktards and you need to learn about it

I built netsys.com, delta.net, Damocles.com, inetexpress.com, USA.net and medicare.com.

I worked for ANS for 6 years building the first fault tollerant internet backbone in America.

It's fucking 2026 assholes... I should be able to multi-task... Like Windows 1.0 back in 1986.

Dear Support Person,

Yesterday, after being notified that an upgrade was available, I executed the upgrade to version 152.0.

The upgrade completed successfully with my eight tabs populating on the left side along with a new tab showing all the features of the new upgrade.

I opened my Gmail tab and my Yahoo mail tab. Eventually, Firefox froze up, saying it was Not Responding. I looked at Task Manager and saw that Firefox was continuing to grab up memory. I ended the Firefox process in Task Manager.

I then opened it again and deleted all the tabs except for one. It continued to grab up memory.

I then opened it in Troubleshooting mode. It errored out, and I sent the report to Firefox support.

The only thing that has changed is the fact that I ran the upgrade to Firefox. Nothing else has changed.

Firefox has been my go-to browser for years. I am using Chrome as my access to the internet now, and cringe every time I go into it.

I hope and pray that you can bring my Firefox friend back to me.

I am anxiously looking forward to hearing from you.

Take care and God bless!

~ Kyle P.S. I just tried getting information from about:support. I was able to copy the raw data and then the application crashed. I sent the Crash Report to you folks. The raw data I pasted in the Troubleshooting Information box.

I am using Firefox version 151.0.2 on android version 16, but I have been having this issue for months, since before 151.0.1. In some fillable fields on some sites, words duplicate as I type and/or the cursor jumps into the middle of a word. This is most frequently triggered by backspacing but can also happen when using numbers or symbols, such as when filling in a date with slashes or dashes. I've also witnessed it happen seemingly randomly.

Some situations in which this has occurred: -the tag field when creating or reblogging a post on the browser version of tumblr -the birth date field on my state's DMV website when trying to renew my car registration -multiple billing fields when trying to enter card information on a ticket vending site -this text box, the one I'm typing in right now to report this issue. Backspacing and using these dashes for this list both triggered the bug during the course of writing this up.

This has gone from merely irritating to actually being an obstacle (in the DMV example I could not get the field to accept any date format without duplicating and had to use the little popup calendar to select the day instead. What if that had not been a option?). My phone says both its software and Firefox are up to date. What else can I do?

Hello, I'm having trouble with my Firefox Nightly Android today. The scrolling is very choppy while trying to browse any article or webpage. It's most noticeable if I quickly scroll down and up. There is a large delay before my page scrolls back up. Is there any setting I have to change to fix this?

Thanks
