Automatically hide taskbar in desktop mode => Enabled Firefox => Maximised When cursor is moved to outer edge of screen, taskbar should unhide (Expected behaviour) but in this case it remain hidden (Reality). Firefox along with all other spinoffs give same result. Chromium based browser works perfect, and taskbar automatically unhide itself.

As OLED screen have became common as monitor, Taskbar auto-hide is must. If this issue cann't be fixed I may have to change my primary browser which I used for almost 15 years.

Kindly, look into it. If Chromium can do it, why not Firefox.

I recently updated to 125.0.1 and now get 'failed to check for updates': - when I manually check (help > about Firefox) (see image) - in 'settings' it also shows 'failed to check for updates' (see image) I never had such a problem with previous versions; any suggestions?

Hello everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox

Here is my system information

I am running Firefox 121.0.1, which is currently up to date, on a slightly older MacBook, which has the latest MacOS it can get: macOS 11.6.8. As the title states, YouTube is almost unwatchable on my machine. The video will pause frequently while audio continues, motion is not very smooth, which is especially noticeable watching sports, etc. I cleared cookies and cache, I have run in Troubleshoot mode as well as tried flipping some switches in about:config that I've seen in YouTube videos and forum posts about similar issues, but nothing has solved this issue.

YouTube in Google Chrome works fine, and I've been watching HD YouTube on this laptop with it for years without any issues, so I doubt it has anything to do with machine specs like RAM, CPU, etc.

I was hoping to make Firefox my new browser and start supporting browsers that aren't chromium based since Google Chrome is going too far with respect to privacy and the freedom to use the add-ons I like (e.g. adblockers like ublock origin), but so far I have not been enjoying Firefox for YouTube. Any help would be greatly appreciated.

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

Several instances of this "verification.exe" malware appear on download history when firefox is opened as shown. Remove from history or clear downloads doesn't eliminate them. They reappear whenever firefox is opened.

Suggestions to eliminate this nuisance welcome.

Recently upgraded to a new laptop, Thinkpad X1 Carbon 11th gen. Running a Wayland-based WM. OpenGL is working fine everywhere except Firefox. Works fine in Chrome, Blender, glxgears, Steam games. Firefox 121 gives the following error:

I've always used Firefox browser instead of Microsoft Edge, and I would like to continue using Firefox. However, it will not run in its current form under Windows 11. Does Mozilla plan to keep it compatible with Windows? I would like to keep using Firefox.

I don't need any images, you know the problems ... Freezes, no internet access.

Hi......,

I have had firefox browser for a while now and it has always worked fine. Now I`m suffering from that internet pages can`t be loaded ( see attachment ). I think,am not sure since the last update. The weird thing is that youtube does work and can just play video`s also 4K. I have read the error report but can`t really do much with it. Is there anyone who can help me in the right direction?

Thanks in advance for the trouble.

Why, with not very many active open windows, and just after opening, is FF using 175% of my CPU, not counting all the separate listings in my Activity Monitor. Plus it's using nearly all 16 GBs of my RAM. With every new update, I pray it will mean the browser will just work, and not use up all my computer's resources, but it just never does. Pretty soon, more & more of us will just give up on this browser, which used to work better, years ago, and has only gone downhill since.

I seem to have gotten something called Google Ad Services. It frequently interferes with my getting to websites and I cannot find how to block it or remove it. HELP!

I recently made the switch to Firefox. I attempted to use the version downloaded from the internet, which I already had installed for a long time, but it would not open. I then used the version available on the Microsoft Store, which worked fine. Eventually, Firefox crashed and would not reopen. A message saying something along the lines of "Are you sure you want to start Firefox in safe mode?" would appear for a split second, and then close. I tried:

-Starting Firefox in safe mode, but nothing happened. -Restarting my computer. -Reinstalling Firefox. -Running as administrator. -Checking it is not blocked by antivirus. -Using the profile manager to create a new profile: The .zip file version opens but does not help, and the version opened by using the "firefox.exe -P" command in Run suffers from the same problem as the browser and opens for only a split second. -Attempting to boot my computer in safe mode with networking, however, the Microsoft Store listed Firefox as uninstalled, and the network menu would not display any networks so I could not reinstall it. -Searching for any Comodo iseguard.dll files, but I found none.

The only thing that worked was searching "Mozilla" in files and deleting everything except what my computer said was part of the system. After that, I was able to open Firefox, but after a short amount of time, the problem started all over. I have no clue what to do and looking all over for solutions is driving me nuts! Please help!

A while ago I formatted my computer, and installed FireFox for the first time. Ever since installing FireFox, I noticed an issue which has been a constant source of frustration, when I rewind any YouTube video the playback volume changes to a lower value, until I rewind again.

I tried looking online, this is the closest match I've found, but there's no solution there

I tested this issue on different browsers (Edge, and IE), no problems there. I tried disabling extensions, no change. I tried resetting FireFox, no change. I made sure that Windows doesn't automatically adjust system volume. I tested this issue on different Video platforms, no problems there.

I use YouTube when I practice (music), so I rewind a lot.

Any help is very appreciated.

Greetings. I can't open most sites I usually visit (even google.com) via my Firefox 98.0a1. This happens since today. All error codes are SEC_ERROR_LIBRARY_FAILURE.

Tried to:

• Disable DNS-over-HTTPS.
• Disable HTTP/3.
• Disable proxy (never had it enabled anyway).
• Disable sending info to Firefox developers.
• Change settings of DNS-over-HTTPS.
• Restart the browser (after each action).

Nothing helps me... But I still can visit some websites, but most common resources are not working for me. Please help me because I can't use Microsoft Edge without getting mentally ill. :/

For a few days now, I have not been able to play videos. I get this message in the video screen: "If playback doesn’t begin shortly, try restarting your device." When I opened Firefox in Troubleshooting mode, the video played OK and then when I stopped Troubleshooting mode the videos continued to play OK. However, on the next day the problem reappears. What's going on? Thanks in anticipation, Frank

Firefox is becoming more and more buggy and more unstable using more than 8Gb of ram in either the apps processes or if not there then in the background processes and when you look into the firefox task manager it reports it is using no more than maybe 100 MB of ram the only way to stop it is to close the one process that is using all the memory. when i investigate using the about:memory function it tries to tell me that it is an extension using the memory but if i disable the 2 extensions i use and reload the measure memory it still is using exactly the same amount of memory. is there any sort of fix for this because i am getting sick of having to have the windows task manager open to close the rogue process every time i use my browser

Please help me remove this blank area section on the web pages. its on all of them on every tab. I have tried restarting and updating. I cant get it to go away.

thank you Mark

I've had a problem recently with some sites (such as support.apple.com, but also others) loading very slowly or not loading at all.

• Restarting Firefox fixes it for a short while
• I've tried changing to No Proxy from Use System Proxy Settings - this, like restarting, helped for a short while
• Unchecking DNS over HTTPS: DID resolve the problem but I'm curious as to why. I enable it with Safari with no problem.

When I try to download a file, the download always fails. This happens no matter what website I'm downloading the file from (see screenshot 1).

This started happening within the last week or so. We are running versions 97 and above.

Firefox is configured to always ask where to save files to (see screenshot 2).

Write permissions to the user's Downloads folder is denied for reasons unrelated to this issue (see screenshot 3). When I re-enable write permissions, the problem goes away.

Has anyone else run into this problem? Is write access to the Downloads folder required now, even if Firefox is not configured to save files to that location? Thanks!

This is happening every few minutes now. It started right after the 97.0.0 update. The 97.0.1 update doesn't seemed to have helped.

I don't use any browser extensions.

I never saw this issue before, and I have been using Firefox as a primary browser for many years. I'm on a MacBook Air, M1.
