Firefox doesn't play Youtube videos. When opening Youtube website, the loading progress bar stops at around 80% and the video keeps showing the loading circle when pressing 'play' button.

Seems like only the tabs that have been opened for a while are affected. When opening the same video in the new tab, the issue is gone.

When the app is force stopped and started again, the issue disappears and then appears again after some time.

Installed add-ons: uBlock Origin Privacy Badger Video Background Play Fix

The issue persists when all add-ons are disabled. Can be reproduced when using a mobile network without a VPN connection.

I haven't tried to reproduce the issue with all the add-ons initially disabled.

I've found similar issues, that are however not limited to Youtube: https://support.mozilla.org/en-US/questions/1411513 https://support.mozilla.org/en-US/questions/1419131 https://support.mozilla.org/en-US/questions/1374967

This issue is focused on Youtube, so that hopefully it will be easier to debug.

Thank you for developing and contributing to Firefox for Android. It's a modern and competitive mobile browser. I appreciate your effort!

I'm encountering an issue on Firefox mobile where in-browser video playback only buffers a few minutes of a video file, plays it normally for a few minutes, and then stops and won't load any additional video. Refreshing the page and scrubbing forward on the video to the point I left off will let me continue for the next few minutes but it inevitably stops again after a few more minutes. It's as though Firefox is only willing to buffer a video when the page is first loaded, and it forgets to keep buffering as the video is played through. This is frustrating for short videos where this would need to be done a couple of times, but is untenable for anything longer.

This issue replicates on any streaming website I use the browser for, it happens on multiple different networks, and it not an issue with any other video apps on my device. So I suspect it is locallized to an issue with Firefox mobile. I have tried updating Firefox (running v 110.0.1) but the problem persists

Is there a fix for this? A setting I'm missing somewhere? Maybe is it possible to increase the buffer limit on the mobile app so that it can load a whole video at once, instead of just a small portion of it when the page first loads?

Thank you!

Hello, I believe that my Firefox android browser updated to version 113 on May 19, 2023. Up until that point, I had no issues with getting notifications sent to my device from the web version of YouTube accessed through Firefox. I could refresh the page and leave the Firefox app and still receive notifications. Ever since the update, every time the YouTube page is reloaded (which also happens when you leave the app) the Desktop Notifications toggle in the YouTube desktop mode settings switches to off. I can switch this toggle back on, the page is refreshed, and this toggle (and only this toggle) automatically switches to off. This happens every time and I am no longer receiving notificationsto my device. The YouTube app for Android is not involved in this, as I use Firefox to access the web version YouTube as an alternative. Please provide information that can help resolve this issue and/or please make a note of this issue so it can be resolved in the future. Thank you so much.

I said it all in the in the opening statement... What else am I meant to say?????????? It worked fine 2 weeks ago..? But now forget it!!!!!!! What has changed....you must know ... So don't ask me just fix it!!!!!!

I have an issue with firefox nightly: https://imgur.com/a/u22dKez It opens youtube video in tab instead of youtube app. But if I refresh the youtube page youtube app pops up.

I tried tuning off and on "open links in app". I have the newest firefox nightly app. My Phone is huawei P40 pro.

I am using the video background fix addon but whenever i minimize firefox, it will play the current video untill the end and will not autoplay the next one. I have to bring forefox to the screen again and then it starts the video.

On my much older Android device, i am using the same setup and have no problem with autoplaying the next video, even when firefox is minimized. Any suggestions?

When playing a video on YouTube the video is choppy and drops around 2/3 of the frames. This happens on every video that I click on.

I have found that if I double tap to jump back 10 seconds in the video it will no longer drop frames and play smoothly, but if I change the playback resolution it returns to being choppy until jumping in the video again.

I am currently running the latest stable download from the play store, and my phone is a OnePlus 8t.

So i just got back on using firefox then this annoying bug keeps happening which is i cannot play a single video thats in full screen mode even though i already click the expand button, any site from youtube, imdb etc. will not play in full screen.

There always this gray area from top like in the line of the front cam of my phone. Before i can watch videos in full screen but now idk whats happening.

Steps to reproduce problem. 1. Navigate to YouTube with Firefox for Android. 2. Open page of any video which has comments. 3. Switch webpage display mode to 'version for PC'. 4. Now the page layout top-to-bottom should be like: - player with main video - list of videos that may interest you - comments section 5. Expected behavior: load comments section below list of recommended videos, like Chromium based browsers do. 6. Actual behavior: Firefox fails to load comments section, perhaps some script doesn't fire up.

When I want to watch a video on fullscreen on my Samsung tablet, Firefox minimalizes throws me to my homescreen. After I go back to Firefox, the video is choppy and has a low fps. I fix it by forward and rewind the video by clicking on the side of the screen. Very annoying. Browser is up to date, please help

Hi guys,

I used to stream podcasts a lot with firefox, no videos only audiofiles. For a few days the audio stops 60 secounds after the display turns of, no matter if autotimeout or manually. I didnt find a setting that helps with my problem and I tried a clean reinstall, did not work unfortunatly. I am using no addons. Is this a bug or a settings problem?

Hi,

I have been watching YouTube videos on firefox android and have been clicking ful screen and landscape has been fine. Then over night a few days ago, it stopped. When I turn the phone to landscape, the video sound is playing but the video is blank, with no picture. It is fine in normal portrait just not when I click full screen when it was working.

I've cleared the cache and history, I've even unistalled Firefox and reinstalled it twice, once from the play store and once as the apk but to no avail. I have also disabled adons, tried the picture to picture, and autoplay but nothing works.

Any help to rectify and return my viewing would be appreciated.

Hi,

On some sites Firefox will not play the embedded videos. For example embedded screencast recordings like those used by employee time management platforms eg time doctor. Not sure of the format maybe webm

Hi, I have a problem with my firefox app. Everytime I play or skip a port of a video, it plays stuttering and return normal only If I rewind some second (if I pause it nothing change). Anyone knows why? Is there some way to solve this problem? I have deleted every data, cookies etc, every add-on and reinstalled the app but nothing changed. I also formatted every setting of my device but same result. Oh, also, this problem don't happen with other apps like gallery or chrome video (I hope bitrate doesn't cause problems).) .

When attempting to enter full screen mode on Firefox for Android, and to get into landscape mode, the browser appears to crash, keeps audio playing, and "entering full screen mode" dialogue pops up. Have to open Firefox again, and can only be viewed in landscape mode while session is continued. To return to non-landscape mode, the app needs to be force stopped, otherwise you only get to see the left one third side of any web page you navigate to. Seems to have started with most recent update. Is there any way to fix?

Hey, Firefox, here are two things that need to be developed/produced/made-to-happen. The ability to: 1) When watching a playlist on YouTube, on full screen, there is currently no button to skip ahead (or go backward) to the next video in the playlist. We have to inconveniently "come out of" full screen to skip ahead (or go back to the previous) to the next video, and then of course re-engage full screen. I'd think by now, in 2023, you could have developed that. You should make Firefox on Android as close to the way the actual YouTube app operates as possible. 2) When in YouTube, the comments, guys...obviously you know you only offer the option to view the comment section as what YouTube calls "Top comments" but you currently don't offer the option to switch to the "Newest first" view. Come on, guys. We should have that option by now in Firefox mobile browser.

Thanks.

And I'm not interested in any stupid people or trolls replying to this. It's just feedback for the Mozilla Firefox company.
