Firefox for Android 技術支援討論區

On YouTube the video will start playing but the rectangle it should be in will still be black, refreshing usually works. Sometimes a video will simply stop playing. Sometimes i have to close all apps and restart the browser twice to get it to work. Sometimes trying to go to full screen will crash the app. Sometimes popping the app out of full screen into a floating window crashes it. This one is new, it's the uploaded screenshot, it crashed mid video and made the video look funny.

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.

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 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.

Dear Firefox team,

Since the two or three latest Updates of your browsers, a strange bug occours everytime watching a video. When I pause it and let it play again, the video goes under quite some lagging/stuttering. The audio is fine, but the video is not on screen is not. I have to go back on the video bar, so it runs smoothly again.

And before it comes, I already tried the usal methods, such as clearing the cache, clearing browser history, cookies, used privat tab, deibstalled adblocker etc. Nothing worked, and it happens even with different versions, such Firefox normal, nigtly, waterfox etc. And with every video player, not just a specific one. And I teued it on two different smartphones. Is there any solution or planning to fix this?

YouTube videos cannot be played in 4K resolution on Firefox; the maximum supported resolution is 1080p. However, when using Chrome browser, 4K playback is supported.

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.

Device: Redmi Note 13Pro+

Does not occur with chrome and duckduckgo browser.

I have an quite annoying issue when I'm streaming something from SVT Play (www.svtplay.se).

The issue is that when I'm trying to stream anything from this site; I've noticed that the resolution is quite messed up. Insted of having an "normal" resolution ( in wich I have all the basic settings such as full screen,Text ON/ OFF etc), the resolution get a bit odd. In the beginning it's just an small screen ( aprox of an 6x6 cm), but when I'm entering Full Screen; the resolution is all over the place+ that the menu bar is missing.

But also that if I'm entering Full Screen mode; the app is " crashing", or should I say minimizing itself and that I go back to my home screen. But stangly the cast isn't interupting. When I'm trying to enterkng the app,the web- adress is missing( not physicaly but just empty).

What's more strange ( or should I say annoying), is the fact that the cast hasn't any stable resolution. Instead of having an normal resolution( cast), it's rather of an 1,5. But strangly the voice is normal. It's only the picture in wich is out of sync. But strangly if I choose the option of limited bandwith it goes back to normal.

But what's more strange is that I have full connection.

I don't know how this came,but since I'm downloading it from Play store. However since the best way is to download an APK- File( in wich my device is compatibel with). Since I have an Samsung Galaxy Tab S9FE ( SM-X516B- series)

Because however on older version it wasn't any problem. It just appear in newer versions.

However when I'm shutting down the app( have activated the option of clear history when close), it sometimes work fine. But in worse scenario I have to reinstall the app.

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.
