I watch Doc Compton through Firefox which allows me to shut my screen off and still be able to listen to him and was able to play my games while listening to Doc. This has stopped a week ago. I already checked my settings which is selected to have picture in picture for this browser. Please help as this is draining my battery leaving this open.

I have animations disabled in Android, but Firefox seems to not honour it as of 1-2 days ago. When I close a tab (viewing tabs, swiping left/right on a tab) it now does some slow fade out instead of just being swiped off and disappearing like it used to.

I searched through the settings but can't find a way to disable this behaviour.

Since all these problems arise on Facebook only, my assumption is that there may be some underlying connection between them. So I'm not just lazy, please bear with me.

Facebook doesn't do attribution properly when sharing a post in mobile Firefox for Android. When attempting to do it manually, the correct suggestions disappear almost instantly if they show up at all, and are replaced by people I have no connection to whatsoever. The keyboard covers comments and posts whilst writing them, when it doesn't disappear for a while. The page might get reloaded at any time during composition, throwing you out to the main page willy-nilly, losing all you'd been writing.

Android keyboard remains open, when firefox app is opened initially and website or search is triggered. But after I hide the keyboard manually, then its fine. But its always open if not hidden manually. This behavior was seen few months ago and still persists.

Closing remote tab on smartphone closes immediately this tab on desktop. But opposite way stopped to work since some update: Remote tab closed on desktop still appear on smartphone. Not any action, notification on smartphone as it used to be. Fresh install Firefox for Android, updated Firefox on PC (Windows11).

I just went to look up a recipe in my Recipes collection. There are no collections on my Home page. I checked Moz support and verified they should be there. This is a new phone and the first time I tried looking for a recipe. I tried to test-save a page to a collection. The dialogue box came up with "Collection 1" in it. Clearly my collections are gone from this install. I just checked my old phone and they're there. It's the same account because the email address is the same and my profile pic is the same. How do I force the collections to re-appear on my home page? Samsung Galaxy, Firefox 155 First image is now Second image is old phone. Btw, I've been Mozilla since the late '90s! Never had an issue like this before.

С недавних пор, перестала работать синхронизация на Android 15. При попытке входа в аккаунт, с QR-code или по e-mail висит пустое окно. При переустановке Mozilla ничего не изменилось. Вход в аккаунт не выполнен.

I really don't like the "swipe right to go back" function on the mobile browser: I always trigger it by mistake and reload a previous page when I don't intend to. It's especially bad when reading webcomics, as I have to zoom in and move aroud a lot on the page, and if I hit the left edge a bit too fast I get sent to the previous web page.

I dug around a bit in the settings but couldn't find the option to disable this function, so if you could add it (or explain where to find it if it's already there) I'd be most grateful.

P.S. Please don't ever add AI slop to Firefox, I beg of you

I exit and close Firefox (mobile app), Launching again > it opens a summary page instead of the page where I was. although the setting is Homepage / open on the Last Tab

For some time now, YouTube subtitles have stopped appearing on my Android Firefox browser.

Pausing the video makes the subtitles reappear, but they disappear again almost immediately.

This is very frustrating. Is there a solution?
