Firefox Community Forum

when I hit full screen in the lower left on youtube videos it says full screen unavailable on all videos. I have tried all the recommended setting adjustments in the config and they don't work. yet full screen for youtube videos works in all other browsers on my mac which is an M2 pro macbook pro running sequioa 15.7.4

Please fix this as it is really annoying and I may stop using this browser if it is not taken care of. It just started yesteday out of nowhere. No changes were made on my computer during this time.

ive been facing this issue since i dowloaded mozilla in my mac mini, and it just randomly decides to not play audio at all unless i shut all of the tab down and re start the entire browser which is very annoying because i am a video editor and i am working multiple tabs at a time and need audio always and since tabs can't restored in the order they were before closing this is sabotaging my work heavily, i love the browser overall but this specific ruins it because its a basic feature

When I open a website that requires my computer's camera, nothing displays except a black box, even though the camera is allowed in both Firefox and on the website.

Apple cs and Geek Squad both deleted app, reloaded from net, problem remained. Geeks said it was definitely a FF problem and deleted the app completely. I am now using Chrome, which I hate. I want my Foxie back!! I am using Mac Mini, OS Sequoia 15.7.4. I updated to this maybe 2 mo ago? Two upgrades were available and I just randomly picked one. I AM NOT A TECHIE. Please respond in language a dummy can understand. I really need help! Thanks!

The last two days my internet performed poorly, but it worked (in between crashes). Now it took me 12 computer restarts and hours of patience to get to this page and plead for any sort of internet. I can't visit any page with moving imagery or it will crash, it won't start any video if there would be sound on it, stating that I don't have permission or simply not doing anything at all. I can't even finish the news-program I was watching on public acces tv. Please fix this!!! I'm desperate! I need to watch instructions for school and see my work-roster and I can not acces any of those pages anymore.

Recently I formatted my pc and after reinstalling windows I immediately downloaded Firefox and synced my profile.

For some reason, videos on some (most websites) are not working at all. They just dont play, and these are websites that I used just last week on Firefox, and that I've tested on other browsers and work just fine. I've tried troubleshooting mode, new profile, deleting cache, etc, and nothing has worked. On some websites, I dont even see the player, its just blank, and in others I see the player but no playback (doesnt even seem to buffer).

YouTube works just fine strangely enough.

Whenever I try to watch videos on websites such as onlyfans youtube, etc., the videos will not play since I installed firefox. I have to shut my computer down and start it all up for them to play. I googled how to fix this and I need to go to settings and scroll to performance and uncheck use recommended performance settings and uncheck use hardware acceleration when available but I can't find this to uncheck these items. Can anybody help me? TIA

Coming from Chrome for a very long time to firefox I am used to clicking an embedded audio opening a new tab with a "playthrough" feature. When I have tried this with Firefox it automatically downloads or skips this preview capability.

When I play a video in fullscreen and type something, when I typed something in the IME and will press Esc to quit the IME, the whole fullscreen will be quitted. The expected behavior is to quit the IME only, and the fullscreen should be quitted only when there is no IMEs.

The issue has been existing for years.
