Firefox for Android Support Forum

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.

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, this issue has been present for a long time for me, and with many versions of Firefox Nightly for Android.

I'm always using the latest nightly for browsing Youtube only, with a set of specific settings and addons (since we can't use profiles on Android yet)

My problem is I've configured the Homepage to never show anything but a few URLs I chose to pin, you can see my settings and my homepage in the screenshots attached.

Despite the "Recently visited" setting being disabled, sometimes, but not everytime, the last pages I visited are added to the Homepage, after the pinned sites. I have no idea what triggers it or not, if I'm doing something wrong or if it's a bug.

Thanks for your help !

I want to update to the latest version but the "Text selection magnifier" is stopping me from updating firefox android. Because I find it pretty useless and very distracting when viewing text while selecting the text in a website/article. Please provide a toggle for it in the Settings.

When i use mozilla in android 13 tablet, and i click on the 3-dot menu while the address bar is set to appear in bottom of screen, i cannot see the full 3-dot menu neither can i scroll to the end of it -only half od it appears. When the address bar is set at the top of the screen,the problem does not exist in landscape view. Please fix it

When commenting on 9gag, the blue "post" button disappears. If I choose "Desktop sight", the entire page reformats and becomes different and I lose all of my posting information.

My computer restated itself with an update. Now Firefox and all my bookmarks and saved log in info is gone. I normally can solve this by simply logging in and syncing from my phone. Firefox will not open a log in page from any of the icons on any Firefox page. I can log in using Chrome but of course sync from there is not possible. I can log in on my phone also. The problem is either my Mac settings or the Firefox settings on that computer. I have searched FAQ etc. No clear solutions can be found.

I have Firefox on my Windows 11 desktop computer. As of today, I cannot see my Firefox on my Android smartphone. The problem started when I saw that my computer desktop Firefox would not automatically update. When I tried to update manually, I lost my ability to use my Android Firefox. Don't know what to do next.

I use the mobile version of Mozilla firefox and it choose to "remove" the open in other app feature for certain apps.

If I open youtube.com mozilla would ask to "open in other app" as an option instead of just opening it in the browser, youtube, twitter/X, reddit, etc. are fine, but for certain apps such as Pixiv and Patreon the option just dissapeared entirely, not even in the tripple dots at the bottom right does this option appear, can anyone help?

Any website that uses OscillatorNode and other similar features has the audio generated devolve into a crackly mess after only a second or two.

Whenever I use Firefox the UI image elements will become oversized making everything squished. I have provided pictures of the incorrect display and what it looks like on my default browser fir reference.

On the Firefox Android app, after closing few tabs, exiting the application and re-entering the application, the closed tabs reappears as if they weren't closed at all. I found this is a well known bug and there are few open threads on bugzilla on this topic. Someone said that's related to a corruption of the closed tabs' json file.

PS. It's difficult to share a screenshot, probably a video is more explanatory

When i try and accept an e-transfer using Firefox, I'm getting an error message "Application error: a client-side exception has occurred (see the browser console for more information". I've always been able to accept e-tranfers in the past.

Hi I've been having an issue with adding bookmarks lately. I have a lot of Bookmarks as such I use a lot of bookmark folders, often multiple folders within one another.

The issue I have is that when I add a new bookmark on mobile Firefox displays all Bookmark folders all at once leading to a lot of scrolling in order to get to a specific folder. This can lead me to several minutes of searching as I try to find a specific folder.

This could be solved by implementing a drop down box to hide folders within folders.

Anyhelp is appreciated.
