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!

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, 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).) .

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!!!!!!

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

Hello,

I'm facing a severe battery drain issue that occurs with all of the current Firefox versions for Android (Stable, Beta, Nightly). I have noticed that the problem mainly arises when I have played any type of video through the browser, such as a YouTube video or any auto-playing html video through a website. And I don't mean that the battery drain occurs WHILE I have the browser open, I mean in the background, after I have exited Firefox. I have also installed GSAM battery monitor with the necessary ADB battery stats permission given, and it seems that the "Video On" wakelock is always on with Firefox. It's like that the thread that plays the video has not stopped, even if I have force closed Firefox, and killed the video tab. For example, I'm attaching two screenshots from the battery monitor, where I have previously opened Firefox and played a video for like 15 seconds (see the "Audion On"), then immediately closed all the tabs and force closed the application. As you can see, the "Video On" has not stopped, like the "Audio On" wakelock, and continues to count (35 minutes). This may go on forever, such as if I leave the phone at night, I'll wake up the next day with Firefox video wakelock displaying something like 15 hours of playback (something that of course, is not true). The only way to stop the drain, is to restart the phone and not open Firefox.

Though, the issue may not even be related with video playback. I have read in the forums (like here: https://support.mozilla.org/en-US/questions/1432706) that other people are facing this issue as well, and worked around it by not using Firefox as the default browser. I have not tried it but, even if it works, this is not at all convenient. Other posts on reddit that verify the same issue I am having: https://www.reddit.com/r/pixel_phones/comments/18xh7w3/why_is_firefox_using_all_this_battery_i_havent/ https://www.reddit.com/r/zenfone/comments/18zlow0/since_android_14_video_seems_to_be_the_top/ https://www.reddit.com/r/firefox/comments/174d13d/firefox_excessive_battery_usage_on_android/

I do not wish to switch to chromium based browsers. Please take a look at the issue and let me know. Thanks a lot.

I tried to open this streaming video from CBS News. It won't open on Firefox but it does play on Chrome. Both browsers are updated to the latest version. (Android)

https://www.cbsnews.com/video/110424-cbs-evening-news/

I cannot upload any file, neither images nor documents. After selecting a file for upload the download/upload speed is reduced to less than 1KB/s and that's it. I still can send emails with huge attachments without any problem.

Whenever I enter fullscreen mode, the entire app minimizes itself and starts playing audio in the background. I have to reopen the app and reenter fullscreen in order to actually use fullscreen and it is extremely frustrating. Is there anything I can do to fix this?

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?

Every time a youtube video is placed on landscape mode on the firefox app of my android phone it becomes a single blurred image with the audio playing as normal.

Youtube seems to work fine on other browsers and I have tried all basic fixes, like deleting cache/data/reinstalling app etc. Appreciate any help.

Edit. Okay I managed to fix the issue so I'm adding the solution here in case anyone runs into this problem. Apparantly youtube playback decided to enable "ambient mode", a feature I didn't even know existed and seems to not play well with a phones resolution.

Just click the settings gear while the video is playing in landscape (mine is on the top right) and disable the "Ambient mode" feature.

Hope this helps.

After last update, Amazon pages do not display correctly and prime video error

We’re experiencing a problem playing this video. For assistance please go to www.Amazon.com/videohelp.

Which doesn’t have any help regarding this issue.

When I play a youtube video in the FF Android browser, with the phone held "normally" i.e. longest side of phone held vertically, and I press the little icon in the corner of the video to make it "full screen", the video ALWAYS, ALWAYS, ALWAYS, rotates 90 degrees, which I dont want it to do. I hesitate to call this "landscape" because I'm not rotating the phone.

This behavior is unaffected whether in auto-rotate mode, or portrait mode. Chrome does not have this issue. My phone is a samsung galaxy A12, Android 11, latest FF browser.

As it says. Maybe a month ago or so the audio stopped working. I know for a fact it used to work because I specifically used ff nightly because it allowed me to play audio in the background.

I changed no settings. Tested on both some video sites I often used to use and also bandcamp. Absolutely no audio. Please let me know if you have any suggestions or need more information.

I'm getting pixelated screen on firefox Android when I interact or tap my phone screen. First I thought this was phone issue but I tried three other browsers and it didn't happen.Green pixels surrounding texts and shapes. It's been really annoying.dont know how to solve it.

DEVS NEED TO BE HELD ACCOUNTABLE FOR THEIR IGNORANCE AND LACK OF CARING. On mobile app. Videos are choppy even after refreshing, clearing cache and data serve no fix.

Swiping up on video doesn't enter full screen mode.

These are known issues for over 4 years. Questions

1.) Why haven't devs fixes these issue. 2.) Why do devs rely on non-employees to mitigate issues. Instead of fixing issues themselves directly. 3.) No other browsing site has these issues, only FIREFOX. The issues are clearly from poor app design and bad coding, so why do devs not fix it eventhough 1000s of people have these issues? 4.) Despite all the negative reviews, devs turn a blind eye and don't fix any issues.

Hello, This may be a wordful but please do consider reading.

Recently im having problems with firefox android. Im on Galaxy Tab S9. When playing youtube videos in landscape mode, there would be elements (thumbnails, texts) overlapping as if they were layered. I tried using different versions of firefox(beta, nightly, fennec) without addons, with default settings and fresh installs but all of them exhibit same problem. I tested on duckduckgo and chrome but theres no distortion. It means that its the problem with firefox.

Another find is that, there is no distortion when im using youtube without logging in. The problem occurs when i log in to youtube. I tried with different youtube accounts and they all have same problem on firefox. Also, when playing videos and if i clear cache and cookies of youtube from address bar, it logs me out of youtube and the distortion is gone as well.

Things I have already tried: 1. Clearing cache, cookies of website, browser. 2. Clearing data, cache of app, uninstalling 3. Using default settings without addons 4. Fresh installs of different versions 5. Deleted firefox folder from android/data/mozilla in hope of clearing corrupt cookies (dunno if really got deleted) 6. Using different account for youtube

Funny thing is problem goes away after logging out of youtube but it shouldn't be a solution. I would appreciate your time, possible solutions for this dumb problem.

Thank You
