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

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

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

Since pretty much the beginning of the internet, pop-ups were deemed a significant annoyance, so much so it diminished and ruined the users’ browsing experience and significantly reduced efficiencies. Hence the addition of pop-up blocking settings to all browsers long ago.

However, for some unknown reason Firefox gives Google a free pass and allows their “sign-in” pop-up that pop-ups seemingly on every website you visit where you then have to then manually close the pop-up on pretty much every single website you visit - even though you have the pop-up blocker setting on ( and the only way to turn off a pop-up blocker is to specifically add a website to allow for pop-ups).

This is absolutely horrible and not acceptable. If you have the pop-up setting on, no pop-up should be allowed to get through no matter what it is or the source. If you allow one pop-up to continue then you should be allowing hundreds of thousands of other pop-ups as well. But you wouldn’t as you know this would be unacceptable, but again, somehow Firefox allows Google’s pop-up to go through and it pop-ups on pretty much every single website you visit.

Note that I selected Privacy and Security Setting as the "topic" above as that is were Firefox has it's pop-up setting (and where you can add exceptions to allow pop-ups for specific websites)

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.

Some websites display poorly on Firefox 119.0 on my Dell computer running Windows 11. Some of the letters of the fonts are too thin and hard to read. They display correctly in Edge.

I have used Inspect Element to see that the font is: font-family: Roboto, Helvetica, Arial, sans-serif;

The problem goes away if I change this to: font-family: Helvetica, Arial, sans-serif;

I do not have the Roboto or Helvetica fonts installed on my computer.

The problem fixes itself if I turn off the setting for "Allow pages to choose their own fonts, instead of your selection above." However, this is not a good solution, because it introduces other issues.

Any help or suggestions would be greatly appreciated.

I have researched this for several hours and tried many of the suggestions online.

1) I have disabled all extensions. 2) I don't have any Themes installed in Firefox. 3) I have tried "Smooth edges of images and text" turned on and off. 4) The problem still occurs when running Firefox in Safe Mode. 5) I don't have a "High Contrast theme" enabled in the OS settings. 6) I am not running uBlock Origin. 7) I have played with Clear Type but the problem was occurring before that. I have tried modifying Firefox's gfx.font_rendering.cleartype_params.gamma to the value of GammaLevel from Windows's registry Computer\HKEY_CURRENT_USER\Software\Microsoft\Avalon.Graphics\DISPLAY1. 8) I haven't installed any fonts on my computer. 9) I tried setting security.sandbox.content.level = 1.

I've tried deleting all history, cache settings. Deleting and reinstalling Firefox. Backing up existing profiles and restarting. NOTHING except starting in Troubleshoot (Safe) mode makes a difference:

I decided to migrate from chrome to firefox, sadly, my experience has been faced with random slow downs or partial loads even on a fresh install. It's weird but it seems that at random times some websites will refuse to fully load or even start loading, it appears that the app is just hanging. This is usually fixed after several refreshes. Oddly enough, even on a fresh install, if I attempt to load up the same website while in private browsing, it loads right away, again this is consistent even on a fresh install, the attached image was an attempt to load youtube after signing in on a fresh install without add-ons, I tried loading up youtube in private and it worked right away. Chrome wasn't presenting this problem on my computer for years. Any ideas? My computer specs are high enough where they shouldn't matter. I'm running an AMD GPU (7900 XTX) but I haven't found any know issues regarding these, to even discard that, I disabled hardware acceleration, but the issue persisted. Running up to date windows 10, installing latest version of firefox.
