Firefox for Android Community Forum

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 I am watching videos in the firefox app, about 70 percent of the time I go fullscreen to watch the video, it will close the app. Not crash, but leave, like I'm hitting the home button. This has been going on for a long time now. Last time I asked for assistance I got "Have you tried closing your other tabs?". I have 12 tabs open. I never have this issue with any other browser. I have 30 tabs open in chrome, with no issues.

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.

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.

I have a Xiaomi phone with resolution 2400x1080 use Firefox on it. And I have annoying issue with YouTube and other video players. Is there is a way how can I hide notch in full-screen video mode? I can do it in setting, but it works only for vertical orientation. Please look at my attached images to understand what I meant.

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

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.

To be really homest, I never had this kin of problem in chrome, your youtube video player has too many bugs. The issues I've faced are: 1.Whenever I play a video, it is always choppy which is so frustrating. 2.This happened so many times, when I turn switch into full screen mode the whole app crashes.

Please look into this issue, I like the UI and that is the reason why I'm still using mozrilla on my phone.

I had trouble with pages not gully loading before and videos not playing and now the videos don't play at all. No matter refreshing, closing Firefox, blocking YouTube shenanigans with ublock (I also get this problem on steam) or unblocking. I would really prefer that I don't have to reinstall AGAIN. I already had to do that not long ago. Can anyone help me with this problem...? Thank you
