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...

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 :https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect(http://example.com https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect)[msbi](https://www.igmguru.com/data-science-bi/msbi-certification-training/)

Thanks,

When I run a virus or add remover like Malware-bytes it considers the application a "PUP: Legacy" item and counts it as an item to be quarantined or removed. The count of items like this are adding numerous hits that keep growing. How can i stop this from happening?

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:

Crash ID: bp-9104d928-4968-488e-ac3d-ed3000231211 Crash ID: bp-a4d3f2d0-6e18-4c22-85db-655d70231211 Crash ID: bp-dd6eafed-2fd7-4fb7-9a5b-960ac0231211 Crash ID: bp-3f979015-56d9-4a56-8f0f-d04f50231211

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?

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.

I am currently encountering an issue where firefox is giving me the PR_CONNECT_RESET_ERROR despite for no immediately apparent reason. I cannot access any website in Firefox.

Steps taken:

- I've deleted cache/cookies. - Disabled all firewalls and anti-virus software. - Removed all plugins / extensions. - Did a clean install of firefox (while keeping my profile). - Restarted my modem/router.

I have no proxy/vpn, so these are not issues.

Please help me!

Hi, I'm looking for some creative solutions to be able to search for Bookmark Folders imported from other browsers. I have over thirteen thousand bookmarks and I have used some extensions to delete the duplicates. However, that has left many empty folders and worse where my Bookmarks have been removed from these folders.

With Chromium browsers, we can simply search for a Bookmark folder by typing it's name. It will show itself in the search results along with Chrome bookmarks. However, that's not the case with FF. Instead, FF allows us to create TAGS. When I search for a known Bookmark Folder (I can see it in the Bookmark Tree) it won't show up.

it's almost 2024 and I find it surprising that Mozilla hasn't yet incorporated searching for Bookmark Folders. At the same time, I am also (not) surprised that Google hasn't implemented TAGS like in Firefox. Unfortunately, neither browser is ideal for searching bookmarks including folders.

Perhaps I'm missing something and there's a feature in the About:config that allows us to search for Bookmark folders.

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.

I found how to backup and transfer my normal bookmarks, however I really need to backup and transfer my bookmark toolbar, specifically on the Mac version. I can only find the PC version instructions and they don't seem to translate between OS's.

Is there a way to transfer all my log ins and their words from my desktop Mac to my new lap top Mac Air. I need to do it possible my a flash drive since the first time I did it by migration and overloaded the lap top with all the stuff on the desk top. After lots of work to delete everything and reinstall the OS I did it by the flash drive. But I don't have all my logins and their passwords on the lap top.

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.

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
