We are currently attempting to automate our Firefox update processes. Currently we use robocopy to push out new versions on release, but ideally we'd like to use the background updater instead. We are currently on 64-bit 119.0.1, on Windows 10 Pro 22H2. We'd prefer not to switch over to ESR if at all possible. I've already reactivated the AppAutoUpdate and BackgroundAppUpdate policies, and DisableAppUpdate is disabled, but I'm still being hit with a UAC Admin prompt when I try to launch Firefox. I tried to bypass it through the registry at [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers], with "C:\Program Files\Mozilla Firefox\firefox.exe" = "RUNASINVOKER", but that also doesn't seem to have done anything. Any and all assistance would be appreciated

I would like my Mozilla Firefox bookmarks to stay on the left side and my bookmark toolbar on the right side (just like it used to be). Now both Bookmark toolbar and Mozilla Firefox bookmarks are on the left side , and I can't even search a Mozilla Firefox bookmark using the search window.

Please help. Regards. E.C

Hello there,

while trying to stream a Live-Stream i unfortunately get the following error, while the stream is loading: "Playback cannot continue. No available working or supported playlists."

Is anybody else encountering this issue?

Thanks in advance.

Sincerely

My Windows Task Scheduler contains an entry called "Firefox Default Browser Agent". If I delete it, it returns. If I disable it, it re-enables itself. Can't be modified either. How do I turn it off permanently?

I already have telemetry and automatic updates both turned off.

In about:config default-browser-agent.enabled is set to false

Whenever I open the find bar while deleting the phrases and words, it shows the one word highlighted or its phrase highlighted on the find bar whenever I reopen after deleting the phrases and words. I need help for this ?

Apprantly Firefox updated last night. I still show all the names of my bookmarks but NONE of them have any information in them. Probably lost my passwords too.

Tried all the fixes shown in prior posts. This is unacceptable !

when i have any of those 2 flags set to true it opens all links i middle click from firefox-view history all the way to left since firefox-view isn't a tab. I'd rather have it force them all to the right by default instead of it thinking i am not in a tab and have no tabs open

A few days ago Ubuntu (22.04 LTS) showed me a message saying I can upgrade my OS (or something along those lines). I click on agree (any button that would let me proceed) and the upgrade took place (without restarting). Along with the upgrade Firefox was also updated to its latest version at the time (119.0). Since then, videos on Twitter play but without sound. On some other websites also none of the videos play. On YouTube, Firefox shows me a message saying "To play video, you may need to install the required video codecs" but the videos play fine; I haven't tried other websites but I assume all would have some issues. Google Chrome however doesn't have this issue and all videos play without any issues.

Note that I have not restarted my computer since the upgrade. I doubt this could be an issue but please let me know if you think this could be the issue.

I did the followings and restarted Firefox but none have worked so far for Twitter and some other random websites that I come across, but they resolved the issue for YouTube and now YouTube videos play, although I still get that codec message at the top of the tab:

sudo apt-get install ffmpeg sudo apt install ubuntu-restricted-extras sudo apt install libavcodec-extra

Someone told me this is because the default Firefox on Ubuntu 22 comes as a snap package and I should install the APT package manually instead so that it works. I prefer not to do this because I have lots of tabs open and have manually changed lots of the settings (including in about:config) that I want to preserve. I would also like to preserve the history of visited websites and keep the current cookies (don't really want to keep entering username/password on the same websites again). So the best way for me is to fix the issue for the default Firefox on Ubuntu 22.

Could you help me figure out what I should do to fix this issue?

Hi,

I've been using firefox for 10 years and this is the first time this is happening on me. Firefox was working fine but it does not work starting yesterday, simple task like opening and starting a new tab firefox took more than 20 seconds. None of the pages are showing anything, even those about:config pages are not working Every other browsers, like safari and chrome is working perfectly.

I tried to refresh, reset, safe mode, uninstall and deleted library/caches/firefox, library/application support/firefox, but the same problem still occurs.

My specs: macos 14.1. intel 13900kf, 6800xt, corsair vengeance ddr5 48gb, wd 850x ssd

Here is what is showing in terminal. Thank you.

I thought that in Private browsing mode, using Tools > Settings > Privacy & Security > Clear Data > Clear > Clear Now cleaned out everything in mid-session. It turns out that's not true, for example, using Firefox View I found that the list of Recently closed tabs in three-bar menu > History > Recently closed tabs was NOT cleared. The only way to see that was with Firefox View, which you could then use to delete items from the list.

With the new version of Firefox (119.0) Firefox View has been removed from Private browsing mode entirely. Thus not only is it impossible to see if the recently closed tabs list has been cleared, but it's impossible to clear the list even if you could see it. That leaves the only way to be (fairly) sure things are cleared out during a Private browsing session is to close the browser entirely, which is an annoying pain.

Why was that feature removed? How can I tell if the recently closed tabs have been cleared without it?

Thanks.

Hi there, Last night I installed some new hardware into my PC, new motherboard and CPU for example. After that, I booted up the PC, everything worked completely fine and I was able to listen to Youtube / Twitch / Spotify etc. through Firefox.

This morning I boot up the PC, everything still works perfectly and I have audio coming from all other sources EXCEPT for Firefox. I have browsed every forum already but can not find anything that relates to me. I can't set my output device, since Firefox doesn't show up in the volume mixer. The tabs aren't muted. I have restarted Audiosrv and Windows Explorer several times. I have re-installed Firefox twice. I have tried booting it in safemode. All of the above hasn't resulted in a single second of audio. I am at a loss.

Kind regards, Siem Hoefnagels

I have firefox for browser and when I open my browser to google. In website has google I type and go's to the top of firefox browser instead google search engine. Please help I want to search in the google search engine. Not firefox browser search engine. Thank you

Dear Friends,

Trust all is well...

PLEEZE put an end to this mystery. Can you BLOCK YOUTUBE ADS or not? If so, how is that accomplished.

Many of the extension are not safe even dangerous to use.

Thank You!

Best, Ralph

YouTube won't start playing in Firefox. No add-ons enabled. The page is fully loaded, but clicking on Play makes nothing.

The fix is to disable "User recommended performance settings" and then disable "User hardware acceleration when available".

The problem is that hardware acceleration is enabled by default. In Edge or Chrome hardware acceleration is also enabled but it won't break YouTube.
