Firefox Support Forum

Since approximately July 2023, Firefox gives me a beachball and pauses for about 10 seconds whenever I change between it and another app, or between one Firefox window and another. The same behavior does not occur with other browsers, likewise whether my connection is WiFi or wired.

I have No Proxy set in Network Settings. I am running a 2021 M1 Max Macbook Pro on Ventura 13.5.2.

I would appreciate any advice on how to troubleshoot and fix. Thanks.

Is there some way to enable and disable specific config settings , on a per-site basis?

For example, let's say I want to disable right-click hijacking (dom.event.contextmenu.enabled) on turtlesaregreat.com, but use the default settings everywhere else.

The Page Info > Permissions panel has some, but not all the ones I want. Is this somehow built into Firefox, or maybe there's an extension?

Thanks.

Hi Mozilla Support,

I've been experiencing frequent crashes with my Firefox browser I've tried clearing cache, disabling extensions, and running in Safe Mode, but the issue persists. It is showing an error that is : secure connection failed

I also check this :[msbi([removed link])

Thanks,

So I just picked up a new laptop (ASUS Vivobook 16x), and everything is fresh on it. Additionally, this only affects some video content in Firefox, with Edge browser unaffected. In brief, what is happening is that within a couple hours of having the browser open, certain video content stops working, specifically Twitter/X videos just spin, YouTube previews stop working, and videos continually load. Netflix videos continue to work, but hover previews stop functioning. I even check the 'Stats for Nerds' on YT and it shows 0 KB network activity in Firefox.

I've tried every basic action I can think of:

• Turning off extensions (only use Ublock and Bitwarden)
• Browser Refresh (x3)
• Reverting from 120.1 to 120.0, and now 199.0.1
• Clearing the browser cache
• Reinstalling NVidia and Intel Drivers
• Running in Safe Mode

Only by doing a refresh or completely closing/opening the app gets videos to function again. This doesn't affect the old laptop or my desktop, which makes me think it's a rogue driver--but then why would Edge function without error over the same period of time?

Are there any settings to play with in the browser that can help diagnose?

My online pharmacy, connected to HumanaCenterWell, no longer opens in Firefox. A message "forgerock, redirect_uri_mismatch" appears. It did work until a few months ago and it does work on Google.

When I upload an image with Firefox, it typically shows a red tint. I've seen similar reports from decades ago so I disabled `gfx.color_management.mode` in `about:config`, but that didn't help, even after restarting the browser and the computer. I disabled a couple of related settings, but that also didn't help. What else could I try?

Oddball minor problem I've encountered on a recent update of Firefox, but also I switched keyboards at the same time, so I'm not sure which causing the problem. I'm on a PC, using an MSI keyboard. Ctrl and Shift keys all work, the ONLY combination that doesn't work is (left) Ctrl + (left)Shift + P. Other Ctrl + Shift key combinations work. If I hold the right Ctrl and either shift, P works fine. If I hold the right Ctrl and the right Shift, P works fine. (left) Ctrl + (left)Shift + any other key shortcut in Firefox or elsewhere works, it's ONLY the P shortcut and only in Firefox and only with the left two ctrl+shift combo that doesn't work.

Any ideas on what is causing this and how to fix it?

when I attempt to open firefox, a window opens: xul runner error: platform version 120.0.1 is not compatible. minversion>=119.0.1 maxversion<=119.0.1 If I click the "ok" button the screen goes back to my desktop.

When on Facebook, Firefox will shut down the network connection so that it can't communicate anymore, no incoming or outgoing traffic through Firefox. I opened TaskManager to try to kill the process, but it leaves a single Firefox.exe process running and it CAN'T be killed. I've tried everything I can think of. In an admin command window, normally Tasklist to check for the process and then Taskkill /IM firefox.exe would work. It comes back with process not found, even though it's in the Tasklist and still running in the taskmanager list.

When trying to kill Firefox, it always says "Firefox is currently running" with the option of close Firefox or cancel. If you select close Firefox, the window just comes up again with the same question while leave Firefox.exe still running in the taskmanager. If you select cancel, the windows goes away and the Firefox.exe process stays running in taskmanager.

So I used Sandboxie (sandbox program) to open another Firefox window to continue, which works fine for a while until Firefox decides to shut down the network connection again. I even tried logging off the user account and logging into a different user account, Firefox is still there, running and still can't be shut down. It's like a bad case of Herpes or Chlamydia or something. Then all I can do is shut down and restart the entire machine.

So to reiterate, Firefox cannot be shut down and removed from the taskmanager process list using the typical right upper corner "Red X" kill, or by way of taskmanager "end process" or "end process tree" and cannot be shut down by an admin command window Taskkill command or logging off and switching users.

I don't know if the "autoscroll issue" is an inherent attached problem or separate, but I have that one as well. I'll be looking at asomething and Firefox with a mind of its own will scroll down maybe 2 to 10 threads, sometimes stop, sometimes continue scrolling all on its own. It's annoying as hell. I will try the layout.css "false" fix and see if that works.

Both these issues only occur on my cheezy 3rd gen motherboard/computer, so the specs for cheezyness...

Firefox (x64 en-US) is our primary browser on 2 different computers: a desktop and an HP laptop. Within days of each other, both Firefox browsers on the two computers began crashing whenever we tried to use them. There has been no error message. Nothing we have done has helped, though we have only tried to fix it on the desktop. We have uninstalled it and reinstalled it on the desktop. We have refreshed the reinstalled version. We have opened it in Troubleshoot mode and it still crashed within 15 seconds. Below are the 4 most recent crash reports from today's crashes:

Hello, can you add better support playback on .mp4 videos? Seems with Firefox it's a hit-and-miss with some .mp4 videos that will play and some that will just show "No video with supported format and MIME type found".

All other browsers will play .mp4 videos without an issue but Firefox won't.

If you can provide better .mp4 playback support that would be greatly appreciated. Thanks

Here's one of those videos for an example: https://drive.google.com/drive/folders/1Fv6SdftiCXeYPQOdF17H2JNpwjMu9P7q

Pretty much a URL string like example.com/videosample.mp4

I did a 'refresh' of my browser, thinking that basic user information would be saved. But I lost all my tabs in OneTab (extension). Is it possible to recover them?

Good morning I would like to ask how to configure (set) the Firefox browser on a computer with Windows 10 so that when clearing cookies and history, cookies and login data that have been added to exceptions are not cleared (deleted) when closing the browser: How this setting should be done (what options are selected) Privacy and security - clearing history when closing the browser Privacy and security - deletion of cookies and site data on closing (exceptions - allow) Please reply Regards Zbigniew M zbigniew14@gmail.com

I can no longer request further information on sites where it is possible to click and the result will be displayed. For example: I read a national newspaper on-line. After reading the article I then have the option of reading subscriber comments. When the button is pressed page says it is loading - but nothing happens. If I then switch to Edge - no problem. So I guess the problem does not lay with the newspaper. Many thanks for your help.

I am trying to migrate from a very old version of Firefox (v. 55) to the current one, but there is an app that is more helpful to me that all the other features combined. That is the "Tab Grouping" app that will not run in any version of FF higher than v. 55.

In my work, which often includes a tremendous amount of research, I need to be able to quickly go from one group of tabs to another. If I had to open all these sites manually, that would take the better part of the day and frankly I don't have near the mental capacity to remember the tremendous number of tabs. I have had a couple replies (Thanks!) to this question sometime back, but unfortunately none were even close in performance.

So, can anyone direct me to an app that will allow very quick movement from different sets of windows/tab groups (please see screen shots below)? Is there anyway that I can get this app to work in Legacy mode? I have several other old apps that work perfectly well in this mode.
