Tonight when I launched Firefox, I started getting everything opening in a new window, rather than a new tab, which is what I have indicated in settings and have always had before. Even if I drag a tab from a new window to a previous window, I cannot close the tab. All I can do is close the window.

For the past few weeks, I have been having problems playing certain Facebook videos. It seems to only happen when I try to play a video that was recorded live. I have tried clearing the cache, I've tried a private window, and I've tried safe mode. I still can't get the video to play. However, when I copy and paste the url to Safari, it works fine. I have been able to play "live" videos while they are actually "live"; it's just that they will not load when I try to play them later. I don't have any problems playing videos which have been uploaded to Facebook; only those which were recorded live. The videos just show a circle in the middle as if they are trying to load but nothing else happens. The length of the video does not matter; it happens with short videos as well as long ones. The screenshot image (of a random "live" video I found) I am uploading shows a partial black circle in the center, which is a spinning circle in realtime. I have circled it in red.

I have webpage (Home Assistant instance) on my local network on which I would like to use microphone (for Assistant functionality). Page is completely local, i.e. not visible from Internet. My issue is I can't force Firefox to allow microphone access on this page. I've tried messing with media.devices.insecure.enabled config, but it didn't help. Is there any way to add such page to some whitelist to allow microphone access? From what I gathered Chromium-based browser provides "--unsafely-treat-insecure-origin-as-secure=..." option but I didn't find anything similar for Firefox. I know I could expose my server to outside network and get SSL certificate (from Lets Encrypt) to make it work, but exposing server to Internet just to get local microphone access somehow doesn't feel like a more secure solution. I could probably also issue self-singed certificate but dealing with that also seems at least annoying.

Playback works correctly usually, but if I jump forward or backwards in time it sometimes never loads. This also completely bricks the whole brower, all other tabs etc, until I close firefox and restart it. This happens on all vods of twitch, and also livestreams where I am able to rewind (subscriber function). I have no extensions enabled, and have the default settings on firefox etc. ("Use recommended performance settings") Video of it happening: https://www.youtube.com/watch?v=3difRLhE-cA

Hello.

Has the profile logic been thought through?

When I set a default profile, I would expect

A) all new pages open into the default B) That firefox always opens the default without request.

This does not happen.

firefox.exe -P is set correctly.

Any ideas? I feel after the profile choice was improved, the basic logic may of been broken.

Thanks

Videos causing tabs to freeze

Whenever I click any link that will play a video in a video playing website such as YouTube, Instagram or TikTok, it will cause the entire tab to glitch out and freeze in on the page it was on before I clicked the link.. The entire tab completely freezes and never unfreezes itself, with the cursor having whatever appearance it had when the page froze, and being unable to click anything. The only thing it can do is type a new URL into the search bar, but the search button/enter bar is also ineffective, so I'm stuck on a frozen webpage unless I close the tab or change to another one. I've tried troubleshooting, fiddling with the autoplay setting and turning off extensions, none of which worked. Any ideas?

Version 154 (64 bit) creates a start menu shortcut in %appdata%/Microsoft/Windows/StartMenu/Programs/ with each and every launch. I have Firefox installed to "C:\Program Files\Mozilla Firefox\

Installing a shortcut at launch is undesirable to say the least.

Is there a way I can disable this behavior?
