For no apparent reason I suddenly found that I could no longer browse via duckduckgo or Google (but could through Edge!). The on-screen response just informed that the sites were not available. I had no idea what could have caused this but a Microsoft fault search identified it is a DNS problem. I prefer to use the duckduckgo and need to resolve the DNS situation. Is this a Firefox problem, and if so, how do I fix it while still maintaining security?

There is a session with 15 important tabs. Previously, all 15 tabs were restored when closing and then opening.

But now, when closing and opening, the following happens: 1) The first time you click on Mozilla startup, nothing opens.Clicking again opens the home page.And everything. 2)When you click on launch, the home page opens.And everything.


In both cases, pressing Ctrl+Shift+t restores the previous session with 15 tabs.

The error appeared unexpectedly.There were no critical sorties.Mozilla's version is the latest.Tell me how to fix it.

Hi All, I want to block traffic on firefox externally for managed devices via Intune, following the import of the ADMX/ADML files into intune.

I have set '\Mozilla\Firefox\Exceptions to blocked websites' to the following

  • //*.mydomain.com/*

which works, however, I also want to add hosts that are only resolving on IPs and not DNS. I can add specific IPs if known, but is there a way I can allow IP ranges? Ie

  • //10.10.*/* (this doesn't currently work)

Of the included screenshot, only the wildcard for mydomain.com and the specific IP currently work

If there is a better way to do this via intune for firefox only, please let me know.

Thanks

Hi, I have been experiencing issues lately with Firefox. Attempting to install it often comes up with errors suggesting file corruption but I eventually got it to install. However, now it crashes as soon as I open it and in the past before a system reboot on my PC, Firefox tabs crashed very often. I'm trying to diagnose the issue. I have completely uninstalled and reinstalled Firefox multiple times.

As my laptop is currently experiencing other issues, if there's a specific driver that is causing trouble, it'd be great to figure out what's wrong and what is causing Firefox to not function.

My specs are: Asus Rog Strix G614JIR - (GPU: 4070RTX, CPU: IntelCore i9, SSD 1TB, 32GB RAM).

I have attached the most recent crash. Any help is much appreciated. Thanks.

Unable to connect

Firefox can’t establish a connection to the server at 127.0.0.1:8080.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

Only some videos play without audio, only in Firefox

I've recently done a clean reinstall of Windows 11 and have noticed that, only for Firefox (134.0.2, build ID 20250120135430), a few videos playback without any audio, yet the same videos play with audio when using edge as a comparison. Most (if not all) of these videos did play with audio in Firefox prior to this reinstall.

Firstly, I'm pretty sure this is not a windows sound mixer issue since many videos on the same page and tab play back with audio just fine in Firefox. The same goes for it not relating to the Firefox setting 'Speaker selection', under (burger) > settings > privacy & security > Permissions because videos of different formats (or using different players) on the same page play back audio fine. The tab is not muted. Again, some videos on the same browser tab play audio fine; some of a particular format or player only play the video, while missing the audio (and where Edge plays the same video with audio).

Another common and potentially relevant issue I've seen is that, this being a 'Windows 11 N" install, it was initially missing the settings > system > optional features > Media feature pack, but that is now something I've successfully added. I should add that windows did report problems when I initially tried to add the media feature pack but, after a very long delay, it eventually appeared to succeed when I ran a couple of DISM incantations that I think ended with - "dism /online /add-capability /capabilityname:Media.MediaFeaturePack~~~~0.0.1.0"

I have the 'Play DRM-controlled content' setting enabled.

Comparing the Firefox vs Edge video playback on this video test page - https://tools.woolyss.com/html5-audio-video-tester/ I get the following results (don't know how to get it formatted/aligned correctly, sorry) -

                           FF vid    FF audio    Edge vid    Edge audio
av1-opus-sita.webm          Works     Works       Works       Works
vp9-vorbis-spring.webm      Works     Works       Works       Works
vp8-vorbis-sintel.webm      Works     Works       Works       Works
avc-aac-nerdist-friends.mp4 Works     MISSING     Works       Works
avc-aac-big-buck-bunny.m4v  Works     MISSING     Works       Works
avc-mp3-sita.mov            Works     Works       Works       Works

And perhaps also relevant is that there's also a difference in the audio-only samples further down the table on the same page -

                   FF audio   Edge audio
audio-sample.mp3    Works      Works
audio-sample.weba   Works      Works
audio-sample.ogg    Works      Works
audio-sample.opus   Works      Works
audio-sample.flac   Works      Works
audio-sample.wav    Works      Works
audio-sample.m4a    FAILS      Works
ac192.mp3           Works      Works
spoonradio-hd.aac   FAILS      Works
audio.opus          Works      Works

Also, every 'v.redd.it' / reddit-video-player video plays the video fine but has no sound when using Firefox but plays both sound and video fine with Edge. Here's one for example - https://old.reddit.com/r/funny/comments/1i7y1nr/rock_paper_scissors/

I've seen lots of similar (but not identical) issues on Firefox video with no audio problems with suggestions a few things to try. In addition to what I've already mentioned above, I've tried the following without success -

- Restarting Windows - Restarting Firefox - Restarting Firefox with addons/extensions disabled - 'about:support' > Refresh Firefox - 'about:support' > Clear startup cache - (hamburger) > more tools > task manager > (click the little profile icon for the page playing the video) - I've checked the settings suggested here: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings

I realise it may be possible to side-step this problem by flailing around with more drastic work-arounds like trying a clean re-install of Windows or a full uninstall and clean of Firefox, but that doesn't really help figure out the problem, which leaves the possibility it could easily happen again to me or others when it might be something that can be more properly fixed or guarded against in Firefox itself, so I hope someone can suggest what might be done to home in on identifying the cause of the problem and so learn whether a more precise fix can be employed.

XUL error is not solved: reinstall is NO option, I did this on one laptop and almost all personal data was gone.

When is Mozilla taking responsability and solve this problem ?

Or is is not solvable and do I have to transfer all my personal data to an alternative browser? a lot of work for a stupid error.

Kind regards,

So I noticed that for websites without CSS files or some websites seem to have Firefox's dark color scheme automatically applied to them. I do like websites auto-syncing with my theme, but I don't want Firefox to force the color scheme either.

My laptop doesn't have this weird side effect so I don't know if it's a feature I enabled or somehting.
