YouTube videos cannot be played in 4K resolution on Firefox; the maximum supported resolution is 1080p. However, when using Chrome browser, 4K playback is supported.

Dear Firefox team,

Since the two or three latest Updates of your browsers, a strange bug occours everytime watching a video. When I pause it and let it play again, the video goes under quite some lagging/stuttering. The audio is fine, but the video is not on screen is not. I have to go back on the video bar, so it runs smoothly again.

And before it comes, I already tried the usal methods, such as clearing the cache, clearing browser history, cookies, used privat tab, deibstalled adblocker etc. Nothing worked, and it happens even with different versions, such Firefox normal, nigtly, waterfox etc. And with every video player, not just a specific one. And I teued it on two different smartphones. Is there any solution or planning to fix this?

I always have trouble playing videos unless I restart Firefox. Today (3/22) I received notice that Firefox had been updated. Now I can't play videos even when I restart Firefox.

Recently, the banner that usually appears when playing a video with Firefox (such as from youtube.com) has stopped appearing. I also cannot pause or play a video by clicking the controls on my headphones, which used to work. And finally, when playing a video or song from another app (eg. Newpipe), the video on Firefox does not automatically pause, which it used to to. I've tried updating both the app and my version of Android, but neither have helped. I would add images demonstrating what the media banner used to look like, but the "Browse" button simply does not work. Please help

I have a Shokz headset with volume and pause/play buttons. I watch videos on my Samsung s21+ using Firefox (more privacy, and easier to have multiple videos up with tabs comparedto YouTube app.

It worked fine up till today, when the pause/play button no longer does anything. I tried restarting the phone, closing and opening the Firefox (Ff) app, force-stopping the Ff app, and turning the headset off amd on. The headset functions correctly in other apps, just not Ff.

I don't want to uninstall and reinstall Ff if I can avoid it, but would that even work? I've done all I can short of that, but it still doesn't work.

I am trying to set my tablet up for use with jpay.com video visits which are live with the prison system in Georgia how do I do that it continuously tells me that the browser is not up to date through Firefox which it is and indeed to download the latest version of their securus vre which I have done. How do I get this to work?

I cannot view CNBC investing club videos (yes, I'm logged in), in Firefox on Android 13 immediately after yesterday's Android update.

Chrome can view videos perfectly.

Firefox should adjust for the latest Android update.

Firefox version 109.1.1 (Build #2015927169), 8f4899e33+

Android build TP1A.220624.014.A136USQU3CVK9

Hey, just wanted to bring awareness to the popout video player being broken in FFfocus on android (on my samsung S21, anyway) as of the latest stable FFfocus update.

As i move the video box up my screen, the video shrinks down, and the box gets filled by a black border. By the time the video player is at the top of the screen, the whole box is pure black.

P.S. this is a throwaway email (sorry), so i wont be able to respond. I just wanted to give a heads up, and the google play rep, told me to make a post here.

Some other potential worthwhile info Android 12 Samsung OneUI version - doesnt seem to matter Web video player doesnt matter

Thanks for making the best web browsers for the past 20 years!

Hello, suddenly when I try Mozilla and play youtube in this favourite browser, I can t have picture and picture anymore and play a video and do other things with my Redmi 5G phone. I looked in the settings and it s set on firefox the picture and picture, but as I said now it s not working anymore

Using the Android app, 105.1.0 (Build #2015904299), if watching a video in the browser, I occasionally notice video/audio desync issues, probably a few hundred ms but very noticeable nonetheless. Whenever it occurs, I try other browsers but never encounter the issue. I have disabled all plugins, I have cleared the app cache, but I'm not sure what else to do. I'm usually wearing Bluetooth headphones when watching videos, I'd have to do something testing to see if it occurs without. Googling the issue, I can't find solutions specific to the Android app. Are there other things I can do to troubleshoot this, or a known solution? Can provide any additional info requested.

I have tested this on multiple devices, it seems youtube has broken their site on firefox for android. I can no longer fullscreen properly, it doesnt auto rotate. It defaults to the 244p resolution for every video, making me have to manually change the resolution everytime i want to watch something, It no longer allows the miniplayer or PIP, and you can no longer press play through the notifications widget as it no longer shows, thus not allowing us to listen to a video while minimized or on another tab. These features all work on other sites without issue which makes me think its a thing youtube did to circumvent adblockers. It's like this on my friends phone too it started at the same time.

Lately Full Screen to Landscape mode for YouTube and other websites is not working (Screen doesn't rotate to Landscape Mode screen stays at Portrait Mode at Full Screen) Please fix this issue.

Hello.

I'm facing a problem with the Firefox app in my Android phone. The problem is that the picture-in-picture mode of Firefox is not working anymore since a Firefox update was issued somewhere in April 2023.

I have always actively been using the picture-in-picture mode and I'm wondering why it is not working anymore. I have gone through the settings in my Android phone (apps section) and the Firefox settings thoroughly but I couldn't find any solution.

In my Android phone, the picture-in-picture mode for Firefox is on (meaning effective) but I couldn't find a separate picture-in-picture mode inside the Firefox app settings itself.

Could you please explain why the picture-in-picture mode is not working and is there is a method how to turn it on (effective) in my Android phone? I have Motorola Moto G100 with Android 12 version.

Thank you for answering and for giving guidance in advance.

As it's already mentioned in the subject, I can't play videos from netflix in browser. Using Firefox's Beta Version latest version 109.0b5 (as per the time of writing). Clicking on playback, the page says either you aren't on the latest version of Firefox or You can instantly watch this title at the moment. Please look into this.

These "crashes" aren't in the Report, so I'm not sure what to do. I've pressed Quit, I've cleared the Cache (twice), and I've deleted and reinstalled the app. Firefox was working just fine until recently. These crashes only to seemingly happen on YouTube and Tumblr. It closes worse when I have the YouYube in Background Add-on on, but it isn't just because of that. If anyone knows how to fix this, feel free to answer.
