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.

Trying to get stuff done. It's hard when you start a task in one tab ,switch to another tab to start another task, and when I switch back to the first tab, it hadn't completed the task, it actually paused when I left it. What's the point of multiple tabs, when only one is working at a time? I expect it to continue with the task, while I go elsewhere to complete a different task.

HI All Recently purchased a laptop and want to have FF sync with my desk top. I am signed in to both devices with the same account and have checked all settings on both and they are identical. Why are they not syncing?

My tabs from a Windows 10 PC were imported to Firefox running on my Mac Studio ( OS is Tahoe ver 26.2). How do I easily recover these tabs and prevent this behavior in the future? Note: I have copied previous versions of the Firefox profiles files to my active profiles folder, but this does not bring back the lost tabs.

I have webpage (Home Assistant instance) on my local network on which I would like to use microphone (for Assistant functionality). Page is completely local, i.e. not visible from Internet. My issue is I can't force Firefox to allow microphone access on this page. I've tried messing with media.devices.insecure.enabled config, but it didn't help. Is there any way to add such page to some whitelist to allow microphone access? From what I gathered Chromium-based browser provides "--unsafely-treat-insecure-origin-as-secure=..." option but I didn't find anything similar for Firefox. I know I could expose my server to outside network and get SSL certificate (from Lets Encrypt) to make it work, but exposing server to Internet just to get local microphone access somehow doesn't feel like a more secure solution. I could probably also issue self-singed certificate but dealing with that also seems at least annoying.

After the most recent Firefox update all my bookmarks were scrambled. For example, when I open one marked Bank of America, I get Go Daddy. How do I restore my bookmarks to what they were before the update?

For the past few weeks, I have been having problems playing certain Facebook videos. It seems to only happen when I try to play a video that was recorded live. I have tried clearing the cache, I've tried a private window, and I've tried safe mode. I still can't get the video to play. However, when I copy and paste the url to Safari, it works fine. I have been able to play "live" videos while they are actually "live"; it's just that they will not load when I try to play them later. I don't have any problems playing videos which have been uploaded to Facebook; only those which were recorded live. The videos just show a circle in the middle as if they are trying to load but nothing else happens. The length of the video does not matter; it happens with short videos as well as long ones. The screenshot image (of a random "live" video I found) I am uploading shows a partial black circle in the center, which is a spinning circle in realtime. I have circled it in red.

A couple of weeks ago all of my bookmarks disappeared from my profile. The toolbar is empty and when I click manage bookmarks, the entire interface is blank. When I attempt to do the restoration method suggested in the firefox guide, nothing happens when I click the restore button from the drop down. I tried logging out and logging back in, but that didnt help unfortunately. Any suggestions or help is greatly appreciated.

After reinstalling Firefox due to it being slow, no matter what settings, Firefox always opens and focuses on a new unwanted tab. But only if there are no extra tabs open except for my 5 pinned ones.

This behaviour started before I installed any Extensions.

How can I stop this?

Playback works correctly usually, but if I jump forward or backwards in time it sometimes never loads. This also completely bricks the whole brower, all other tabs etc, until I close firefox and restart it. This happens on all vods of twitch, and also livestreams where I am able to rewind (subscriber function). I have no extensions enabled, and have the default settings on firefox etc. ("Use recommended performance settings") Video of it happening: https://www.youtube.com/watch?v=3difRLhE-cA

Hello,

For some reason, when I try to sync all my stuff from my desktop Win 11 firefox/duckduckgo system, to my new Win 11 laptop, the only option I can get is to sync with a mobile device.

I had no trouble doing this some months ago with another laptop, but this time I cannot find how to do this after trying for over an hour . . . . . .

Has anything been changed that won't allow syncing with another 'big' device, please?

Hi everyone,

After a recent series of updates to both my mouse and Firefox, my mouse no longer scrolls within Firefox. The mouse is Logi wireless mouse. Firefox is the latest version. The mouse scrolls fine in other apps, like WhatsApp, Outlook, Word etc. but not in Firefox.

When I try to scroll in Firefox, it stutters, jumps and will continue to jump even when I stop scrolling on the mouse.

I have spoken to Logi and there is no issue with the mouse itself.

I have tried Troubleshoot and Private mode, but still the same issue, so its not an add-on or extension problem.

Is anyone else having this issue over the last couple of days, or have any ideas on how to get back to smooth scrolling?

Thank you, Graham

I have st installed Lime on my old Asus Zenbook an have installed Nord VPN. I am using the Firefox browser showing connected to the internet but am unable to access my webmail account and its popping up messges advising Problem loading webpage and another showing 502 Bad gateway. I am also having problem with the Zenbooks Keyboard with keys randomly not operating when pressed but will work after a prolonged or multi pressing.

For at least a few months now, my browser will suddenly and randomly go fullscreen all by itself. I can't exit it, and then it goes back to normal after at most a minute. It hasn't happened in at least a week. But today, it froze like that, not responding. I quit firefox, waited a bit, then restarted it. It went fullscreen and froze again. I waited at least 10min and it then went back to normal and responded again. It only happens when using firefox. I've done virus scans, etc, and it still keeps happening. Please help. Thanks.

I just recently installed the VPN on Firefox. It hadn't shown up because of my privacy settings. It works fine except for the United States connection. When I choose the other countries, it works fine, but when I choose United States, it still shows Japan (where I live). It still shows Japan, but it does have an effect. It changes it to Tokyo, where I don't live. So, the vpn is having some effect, but it is just not connecting to the United States. Why is that?

Tonight when I launched Firefox, I started getting everything opening in a new window, rather than a new tab, which is what I have indicated in settings and have always had before. Even if I drag a tab from a new window to a previous window, I cannot close the tab. All I can do is close the window.

This should be simple. Your site sends a message saying do I want to update MY TABS WILL BE RESTORED. It DOES NOT say I need to go through history and check forums and consult outside parties. I'll keep this in mind the next time a silly tedious update comes around.
