Firefox for Android Support Forum

Hi. I can't watch a video on any website after updating my android app to v.(126.0 I think) because it plays Stuttery and laggy. I don't have much tab open, mainly 2 or 3 and incognito mode doesn't makes any difference. Still videos play laggy as if it's on low fps. The recent update to v126.0.1 didn't fix it either. My phone is galaxy s21 ultra if it matters.

I can't remember when this problem started, but the volume dips down for maybe 1-2 seconds shortly after the start of anything with sound, like YouTube videos and MP3s embedded in a website. On the same phone with Chrome, the problem does not happen.

Has anyone experienced this? I made a screen capture that demonstrates the problem, alternating first with Chrome, then with Firefox (then both again) -- https://youtu.be/GB116jauaX4

Any help anyone could provide would be greatly appreciated!

I'm uploading this on chrome.

The add function does not let me add photos or videos to any website requiring photos or videos for evidence. The "Add Photos (optional)" only says allow but does not upload photo. All permissions are allowed on Oneplus 12.

Listening to audiobooks made me notice this problem, often whilst my phone is turned off and the audiobook is playing in the background on a tab on firefox the audio would just stop and i would find either that firefox was still open but unloaded all the tabs, or that it simply crashed. I thought this was a thing that solely happened when playing audio in the background but then i noticed that it is actually a general problem when firefox is kept open in the background. It doesnt happen after a set amount of time, sometimes it happens immediately, sometimes after like 10 minutes that it is kept in the background. How can i fix this? its very annoying.

Videos are lagging frequently, seems like the fps drops a lot. It usually happens as soon as I pause or skip forward/backward. It doesn't depend on the source of the video, as it is the same for all the websites. My network connection is stable. Pausing or reloading doesn't help, the problem is persistent at all times. I have to skip backwards then forwards to the same spot. I use Samsung Galaxy S20 and Samsung Galaxy Tab S8. Firefox version 126.0 (Build #2016019903)

Hi Guys!

Can high resources eatin' (maybe graphics, IDK) Ads, for Me in the Webside embedded and (sometimes) with 'movie' like movement decorated, automatically get blocked?

My phone runs slow, 'even' with just 1 Tab open and only Firefox Mobile App on the phone active.

Sorry, I can't see the field I type in currently, maybe I writ a bad layout right now, but content matters XD.

When displaying an iframe video in a popup, clicking the close button and other click events do not work. This issue only occurs in the Firefox browser on Android, while it functions correctly in the Firefox browser on iOS.

Is this a default behavior.

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.

Every time I'm trying to stream video like live sports the video lags so much. I've tried to reinstall the app and run it with no addon ( even though I only use 2 addons) and problem still persists... I'm using a Samsung S21 Ultra.

The upload photo button does nothing... on this page, on Reddit, Facebook too. I've tried clearing cache. I'm on latest android and firefox 124.2.0. I have standard security enabled and permission is set to "Ask" for camera and storage. How do I make this work again?

During video streaming and visiting sites, that use animation while browsing, artefacts appear. Tried reinstalling firefox, clearing data, disabling addons but to no avail.

On video streaming it occurs specifically when playing the video and interacting with the in browser player i.e. just bringing up the seekbar or playback speed.

Does not occur with chrome and duckduckgo browser.

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).) .

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.

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.

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 .

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
