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

Hello,

I am getting a frequent freeze in the Android app and then shortly after a crash. Info: - happens on FF, FF Beta, and FF Nightly,and reinstall/phone reset didn't fix. - Samsung Galaxy SM-G965U running Android 10. - every error starts with java.lang.OutofMemoryError. - it never happens just on startup, just on auto fill, or some of the similar crash reports I've seen around here. - it does appear to be site-specific, but sometimes the site works and sometimes it does not: if I close the last tab after a crash, it will usually work for awhile. - Sync and disabling Add-ons doesnt fix it, although perhaps its worse with uBlock Origin enabled (not conclusively)

Thanks for any suggestions.

I'm having the same problem as this guy.

I have a large number of open tabs in Firefox on my iPhone, a mixture of old and very old. I've been trying to go through the tabs and deal with them -- in some sense they are all todo items that I left open at least semi-deliberately.

If I tap on a thumbnail to load a tab, Firefox instead loads a blank page. If I tap the address bar after that, Firefox loads the new tab page, not the site corresponding to the tab that I selected. If I tap and hold a tab's thumbnail, Firefox crashes.

It was the case temporarily (possibly a bug) that some of these tabs would place a TLS failure icon in the left of the address bar when selected, while the blank page was displayed. Tapping on that would display the tab title, but not the tab URL. No longer is that TLS failure icon ever visible.

Recently I migrated to Firefox to get rid of the unbearable heavy load of ads on Chrome and would be satisfied with such change if it was not by the slow way Firefox handles Youtube player. As I touch to maximize the screen it is a painful process : the image rotates to a smaller rectangle and after some seconds finally fills up the screen. Once in full screen video player control no longer works. The same did not occur with Chrome , in full screen I used to have control. I noticed previously on my desktop running Windows 10 that Fireworks it is much slower to go full screen on Youtube and to exit full screen. I think Firefox handles with more difficulty the Youtube player than Chrome , or perhaps I am missing something. Unfortunately I think I will have to return to Chrome on Android.

Hi It is impossible to use Firefox on ios 17.2 because it continuously crash. Realle, the issue arise months ago Can you solve the issue or can you send me instructions in order to solve the issue? Regards Mario

For months now, Firefox Mobile has constantly been getting "app has stopped responding" crashes and even hard crashes (multiple times per day) for Pixel users. There's already a bug report about it but the FF team's response is that they aren't going to do anything. They claim it's an issue with the kernel but no other apps / browsers on the Pixel have this problem.

This is beyond pathetic. Maybe this not-my-problem mentality is why Firefox has reduced to less than 1% penetration.

To be really homest, I never had this kin of problem in chrome, your youtube video player has too many bugs. The issues I've faced are: 1.Whenever I play a video, it is always choppy which is so frustrating. 2.This happened so many times, when I turn switch into full screen mode the whole app crashes.

Please look into this issue, I like the UI and that is the reason why I'm still using mozrilla on my phone.

Sometimes whenever i use twitter it will crash and stop working everytime i switch a other tab it glitches and stays on the tab i switched from, and it would also black out and make the tab unusable.

Hi support team,

I was using Mozilla Firefox on my Samsung Galaxy s20+ without any issues. I have transferred all data from my old one to new one, Samsung Galaxy S24 after this migration Mozilla Firefox crashes, when I was forwarded from an app.

Standard browser: Mozilla Firefox I have already reinstalled the Mozilla. This action works properly with other browsers.

Kind regards Mustafa

Hi running latest firefox for Android on Pixel6a. Whenever I full screen a video, it minimizes Firefox and I'm back at my phone's home screen. After this happens I'll reopen Firefox and full screen the video it will work properly.

Hi @all, Such quite a while, Firefox almost constantly crashing when closing a or better the last open tab. Tried a support hint and deleted cache and everything and after that it worked for a few days and then it coming up again. When it happens, and I restart FF and try a logged in page directly, I.e. Facebook, FF doesn’t recognize my signin. Closing the tab, waiting a moment, restart the page again and everything is fine. Really don’t know when this behavior begun, but it is really annoying. I face this problem on 2 different iPad Pro. The newer one from last year with an M2 processor and an older one with an Axx don’t know which one exactly. What’s the matter with that? Kind regards Frank
