Firefox für Android-Hilfeforum

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.

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. It stutters even if I have just Firefox opened video

When i enter fullscreen mode on my phone the android UI elements sometimes doesn't hide (see image). This occurs on sites like youtube and any other site where i try to play content in fullscreen.

There is a bug when accessing the desktop version of the website under the Android version of Firefox. Visit youtube.com on the Android phone, then click on the desktop version of the website, and then click on the video to go full screen. After going full screen, the bug appears: the control button under the video cannot be clicked. This bug does not appear in the Android version of Chrome browser

Hi. first of all, your android app is awesome. That you can listen to videos or YT videos when the app is minimalized or the phone screen is locked is great feature. BUT I am not used to it and I would prefer to change the settings so when I lock the screen the video automatically pauses and does not keep playing....

Any way to achieve that??? Thanks !

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

Video playback initially works, until suddenly it doesn't; no new videos will work, and videos that previously played in the same browsing session will stop working. Easy to reproduce on Reddit by browsing any video-heavy subreddit. Leaving a broken video in a tab seems to infect the rest of the browser across websites; if a broken video from site A is open in another tab, videos on site B won't play.

Sometimes quitting and restarting Firefox is enough to temporarily get video playback working again; sometimes I have to manually clear the browser cache; at least once I've had to reboot my phone.

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.

I'm getting pixelated square and background images on Firefox for Android . I also did same post 5 months ago but issue is still not fixed. I have flagship killer device so my phone can render graphics so it's must be App issue.i'm attaching screenshot here so Devs can fix this issue .

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.

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

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'm having a problem with playing videos on websites. When I click the expand to full screen button about half the time the full screen video comes up for half a second and then the window shrinks down to a small square on the bottom right-hand corner of my screen. Sort of like when the youtube app minimizes a video. This window is unclickable and also everything at or below it in android is unclickable while it's there. If I click the window button on android and swipe the firefox app up to close it and restart it, Firefox doesn't even close and I can still hear sound from the video. I have to select on the Firefox app again which will restore the full window and then click the full screen button one more time and it will work. This issue is happening on every website I play video on on the Firefox app and it is extremely irritating. I'm about ready to switch to another app if this can't be solved, but Firefox is the only browser that allows ublock origin so I don't want to do that. Can anyone help?

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?

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
