Firefox for Android Support Forum

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?

I thought half my apps were gone randomly, then I realized they are all the ones that were web pages Saved to Home Screen, by Firefox! I'm very upset because there's no way I can remember all of them, how can I restore?? Android, no desktop fixes please!

Having web pages with missing, truncated text or blank rendering similar to error reported to Mozilla support by -

Duck Duck Go list of search results has missing text and blank space, for example. Same missing text happened with earlier version of Firefox but is worse with this version update. Have Motorola moto 6g play phone.

The picture-in-picture function no longer works on my phone when viewing YouTube videos on my Android Firefox app.

In previous versions, I was able to enter full-screen mode while playing a YouTube video, then click the "home" button on my phone, and the video would play in picture-in-picture mode while I scrolled through other apps.

I am fully updated as of today (4/11/2023), I have tried the functionality with no add-ons and with the "Video Background Player" add-on, and I have double-checked to make sure that the "picture-in-picture" permission is checked for the app (it is).

My device specs are attached in the image below.

Thank you for your time and consideration.

Dear Mozilla support,

For a while I have the problem that when I want to watch a video fullscreen on a website e.g. youtube, inline video etc. Firefox stops and completely closes. This is only the first time when I play the video. When I re-open the browser I can continue watching the video fullscreen without any problem. I don't receive any error messages.

Attached the specs of my phone and Firefox browser.

Kind regards, Rick

Firefox is failing to display text properly on pages. Paragraphs are getting whited out at seemingly random. If I zoom or highlight the missing part I can usually get it to show up.

I'm using the android mobile version.

I've tried: Clearing the cache Uninstalling/reinstalling Firefox Deleting all add ons Restarting my device Changing font display sizes in Firefox and on my device

It's only Firefox, pages display properly when I try using a different browser. This has been an ongoing problem but its suddenly effecting huge chunks of text on all websites where previously it would only block a word or two on some websites.

(It was even effecting text while trying to type this ticket which is super annoying. )

I want to add a shortcut to my Android device's home screen for a specific location within a popular website (github). However Firefox doesn't allow me to do that, as the option to "Add to Home screen" changes to "Install" (i.e. prompting to install it as a web-app).

While the "Install" option also places a shortcut on the home screen, it doesn't allow for a specific URL, rather it just leads to the github login screen instead (just as it would with an "app" you wish to use). I don't want that, I want a shortcut to a specific page within github.

Is there any workaround for this? Can this behavior of "Installing" web-apps be disabled somehow in about:config, so that all websites can just be added as regular shortcuts?

I'm using FF Nightly for Android, btw.

Thanks in advance!

Why can't you sync your Collections between different devices? I have a lot of web addresses saved on my other devices but I can't seem to "move" my saved Collections to my current device?

Lately Full Screen to Landscape mode for YouTube and other websites is not working (Screen doesn't rotate to Landscape Mode screen stays at Portrait Mode at Full Screen) Please fix this issue.

Firefox rejects ALL service requests. Left on address line is a "human being symbol" with red backslash bar over it. How to recover?

(When problem appeared I have not touched any settings. Phone power off/on does not help.)

"Can you provide guidance on how to optimize my search experience in Mozilla Firefox? I'm looking for tips and settings adjustments to enhance my search efficiency and accuracy. Thank you!"

Although New Build Claims -- Fixed the problem that caused full screen YouTube videos to exit and switch to portrait mode when changing quality or speed. But issue still persist screen doesn't rotate to Landscape mode in full screen mode. It stays in portrait mode with caption below entering in Full Screen. Works Flawlessly in Firefox Nightly

While searching for something in Google, and when I'm tapping on the suggested images with the search results, the page is freezing. That's happening everytime when searching something in Google. Note: I'm using the Google search fixer add-on.

Firefox doesn't play Youtube videos. When opening Youtube website, the loading progress bar stops at around 80% and the video keeps showing the loading circle when pressing 'play' button.

Seems like only the tabs that have been opened for a while are affected. When opening the same video in the new tab, the issue is gone.

When the app is force stopped and started again, the issue disappears and then appears again after some time.

Installed add-ons: uBlock Origin Privacy Badger Video Background Play Fix

The issue persists when all add-ons are disabled. Can be reproduced when using a mobile network without a VPN connection.

I haven't tried to reproduce the issue with all the add-ons initially disabled.

I've found similar issues, that are however not limited to Youtube: https://support.mozilla.org/en-US/questions/1411513 https://support.mozilla.org/en-US/questions/1419131 https://support.mozilla.org/en-US/questions/1374967

This issue is focused on Youtube, so that hopefully it will be easier to debug.

Thank you for developing and contributing to Firefox for Android. It's a modern and competitive mobile browser. I appreciate your effort!

Every time I try to go to a .onion site I get a message saying "you are trying to reach an onion/hidden service. To access (site) via web you will have to use the tor browser" but I am on tor browser.
