Firefox for Android Support Forum

On youtube mobile site or a reddit video, when I click the bottom right button to fullscreen the video, a message pops up that says 'entering fullscreen mode' (with a firefox logo on the left of the message) and then firefox closes and I'm at my android home page

This seems to happen when I watch videos in a new instance. If I reopen firefox to the video and then try fullscreen again, it goes full screen no problem. So basically it's annoying and happens when I try to watch any video full screen for the first time.

Is this a known bug? Wasn't an issue on my old phone (I just got the galaxy s23).

Firefox is fully updated from playstore. Only addons installed is ublock origin and Privacy Badger

Thank you for any assistance

My pixel 5 still has the bug that Mozilla claims they fixed where if you rotate the screen of a video to landscape then it will send the app to the background or will not fully rotate and more the half the screen will be cut off. Will this ever be addressed? It's been months now.

The only 'fix' seems clicking on the app and sending it to the background over and over.

Frequently crashes without warning, pages lag constantly where scrolling down is impossible, even after the page is refreshed. Creates way too many new tabs (like 50 a day) and ads mess up the design of the webpage.

I am posting this issue at the request of E from Firefox's app developer feedback after I submitted an app review.

The app continues to be unstable on my Pixel 6a (latest OS, Android 13) after freezing up on what appears to be any heavily scrolled pages or those that create a heavy cache. This freezing then causes abrupt phone restarts shortly thereafter, but not always immediately. Usually the culprit seems to be linked to Facebook album viewing, Imgur albums with article-length descriptions, etc. The abrupt phone restarting occurs whether force stopping Firefox and clearing the cache right away or not (although the restarts seem to happen faster if I force stop the app). I have simply closed the app during the freeze, put my phone down, and come back minutes or hours later to it having restarted on its own.

In addition, open tabs have a tendency to lose their scroll spots on a non-infinitely-scrolling page (e.g. an article not requiring expanding) when the app is minimized but not closed. This is probably unrelated(?) and isn't as critical as the spontaneous restarts, however.

It looks like many Pixel 6a users have had this issue, although those support threads from 8-9 months ago have now been archived. Someone else mentioned scripts from the websites themselves may be to blame? Would be curious to hear of any specific fixes. Thanks!

Dear Concern, Suddenly I Found Crashing Problem In Fire Fox New Updated Version. When I Try to Save Any Image Or Download Any File From it’s show A Crashing Problem. I attached A Photo Of This Crashing Problem. Sir Please Fix The Problem As Soon As Possible. Thank You.

Recently firefox for Android started crashing instantly upon opening the app. Tried clearing the cache, making sure it was updated, uninstalled then reinstalled. Nothing has fixed it.

Worked great up until a few days ago so I'm assuming something in an app update messed it up.

Android 12, LG V60.

Thanks,

Firefox Update 124.2.0 (Build #2016012559), 7a0e399c7b+ GV: 124.0.2-20240401114208 AS: 124.0

Fire HD 10 (11 generation) Build 0029294005124 FireOS 7.3.2.9

Logged into Mozilla, Sync now does nothing, "Last synced: never" Also crashes frequently all since last update.

as the title says when downloading a file, firefox causes com.android.phone to crash. enough crashes causes my tablet to panic and auto restart itself.

the only app that can cause this is is firefox, downloading files via something like discord, doesn't trigger it, only firefox. i tried with other apps to no avail.

it started happening after an update (update TB-X606F_S301018_230810_BMP ) (the last update was a year ago so lenovo isn't gonna fix it on their end anytime soon) and it's quite annoying when i need to use firefox to download files to view/use.

Details:

 Device: Lenovo Tab M10 FHD Plus (TB-X606F)
 Android Version: 10
 Firefox version: 117.1.0
 security update: 2023 Aug
 Google play system update: 2023 May
 Lenovo system version: TB-X606F_S301018_230810_BMP

Very often when clicming the adress bar (almost always on sites like old.reddit.com, the app just stops responding and I must reopen it. I'd like a solution that won't involve removing all my bookmarks, history and saved data.

After updating Firefox for Android, my phone started rebooting after downloading any file. This makes it very difficult to use the browser and I had to use Chrome temporarily. The Crashes tab in About Firefox is empty. I tried to collect a logcat and uploaded it to Google Drive (maybe this will help somehow.): https://drive.google.com/file/d/1kmdS5rTH3r0u09KLxeUDeY5U8r5xiEK1/view?usp=sharing. I hope this information is helpful in solving the problem.

I have being using this particular browser for a long time. It worked for me very smoothly. However, since in the recent past I was faced with bad browsing behaviours. Delayance,crashes, and failures among others. Kindly advise?

Poco F2 Pro is hard crashing requiring device reboot, starting maybe a week ago, and has happened three times. I don't know if it's hardware related but I've not seen the behaviour in other apps. I'm not using beta version.

Constantly crashes with the latest 3 updates. Not sure if it's on your end or the providing web sites not knowinghow to program for Android phones.

    Too many non standard screen resolutions out there for each phone???

Guesses...???

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

Hey there!

Below is the crash log I pulled from the Android app, which wasn't letting me open a Microsoft Forms link.

Any ideas what's causing the crashes?

Thanks in advance!
