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.

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?

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

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.

video on websites dont play very smoothly. they are always choppy, and look like they are playing on a really low frame rate. the same os true for youtube, instagram where it is very laggy when any video is played. ps. im on android, cant seem to open about:config area

Hello world! (Sorry; had to.)

I just started using Firefox for Android, as a workaround to the problems I'm having with playing my YouTube playlists.

But, I'm having several problems in Firefox for Android.

1. Playlists (the actual lists of videos) cover the video that's currently playing. My workaround to this is to play in full screen mode, but that brings up problem

2. Full screen videos automatically switch to landscape orientation, despite system settings, with no apparent way to switch back to portrait orientation without also exiting full screen mode. I've tried rotating my phone with auto rotate on/off; neither setting has any affect on the orientation.

What's extremely frustrating about this is that any workaround is actually a workaround to a workaround to a workaround; it's workaroundception.

What I really really want is to be able to simply play my playlist/listen to it without having to jump through hoops and without having to burn through data like a bonfire burns through sticks.

IMO, the best solution would be to download the entire playlist:

https://youtube.com/playlist?list=PL-Hu9zPsGgiUKHoc2GeRo6ydKQMIQy8Pt&si=LzYVEe1sd8T1knZF

...in one go, and stick it on an mp3 player like it's 2009. So far, the only YouTube to mp3 sites I've found only download individual videos; not whole playlists. (And that's not really a Mozilla issue anyway; the Mozilla issues are the unwanted rotation and the video stack covering up the currently playing video.)

I always have trouble playing videos unless I restart Firefox. Today (3/22) I received notice that Firefox had been updated. Now I can't play videos even when I restart Firefox.

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.

When firefox updated all of a sudden when I go to youtube sound will not play. My music has sound, when I go to chrome and safari youtube has sound. I have done everything in your help section (Not blocking - allowing audio on all websites etc), clearing cache and cookies and restarting - still no audio

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.

Two questions: 1. I have a 30 mega bite DSL internet connection, but when I watch some videos I get the whirling circle, sometimes another. Also while the video is paused/locked, it continues to run in the background, so I loose the video during that time. A work around used to be, use the forward or back buttons. This brings me to the second question. 2. What happened to the Forward and Back 10 or 15 seconds buttons or circles? They seem to have gone away recently.

Hi,

I face this two issues:

1- if you open a photo inside google search, you can't change the browser to Desktop mod

Here is a video: https://share.stars-host.com/firefox/1.mp4

2- I was registering on one of the sites and i leave for second on another app... When i return i found that all the data that i enter to register was removed because firefox refreshing the page 🥲

Here is example video: https://share.stars-host.com/firefox/2.mp4

The second issue need to be fix because i use another browsers when i want to register for Governmental things, for example, that require me to enter the passport number, which is in the photo gallery...

There is a lot of data that you entered and then it is deleted in an instant when you move to another application for a few seconds (there must be a strong temporary storage space

Best regards, Yahya

Videos "stuttering"/ choppy but audio is fine. Tried watching in many sites but have the same problem. Videos is working fine in other browsers.

Latest Firefox Android version - 122.1.0 OS : OneUI version - 4.1 Android version - 12 Phone - Samsung S10

Have the uBlock Origin add on installed as well.

Hi! I been using youtube through firefox on my phone for awhile now. Mostly since it allows me to play the video when the screen is off.

I have now swapped phone to a HTC U23 Pro. After the change everytime that i look at a video now it stutters a lot. No matter the network connection.

On my old Samsung A71 it still works fine.

It works fine in the youtube app or through grayjay.

Have removed every add on i have and resinstalled firefox but the issue is the same.

Any tips on what i can do to fix it?

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
