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

I am writing to seek assistance regarding a challenge I have encountered while attempting to install a custom add-on from a file.

I have followed the steps to enable the debug menu on Firefox Nightly, and I have also successfully downloaded the custom add-on in XPI format to my mobile device. However, upon navigating to the Add-ons settings, I am unable to locate the option to install the add-on from a file.

I have reviewed the official documentation and community forums for guidance, but I have not found a solution specific to my situation.

Could you kindly provide detailed instructions on how to install a custom add-on from a file on Firefox Nightly for Android? If there have been any recent changes or updates in this regard, I would greatly appreciate any information or resources you could share. Thank you for your time and assistance. I value the work Mozilla does to enhance the Firefox experience and am eager to resolve this matter.

Best regards, Saad

Android System UI crashes after a download completes in Firefox for Android.

About a week ago my phone (Sony Xperia ZX2 Premium running Android 10) started 'crashing to the lock screen' whenever a download finished in the mobile version of Firefox. If multiple files are downloaded in short succession a popup will appear informing me that the 'System UI keeps stopping', with a prompt to close the app or to get to the app info (see the attached photo - clicking either option sends me back to the lockscreen, with the only difference being that after unlocking the phone the former will have stayed with Firefox in focus, and the latter having opened the Settings app on the System UI entry).

Going to about:crashes shows no recent crashes on Firefox's ends. (Plus, Firefox shows no signs of having been closed [like tabs being reloaded] after unlocking the phone again post-crash). The issue currently only happens when downloading a file through Firefox; downloading a file through Edge, Discord, or the Google Drive app produces no problems.

I have already tried force-stopping and restarting Firefox, restarting the phone, and clearing the download history with no luck. Furthermore, I have also checked for updates for the system, the Google Play Store, and Firefox for Android, however all of them were already up to date.

Any help would be sincerely appreciated.

When I play a youtube video in the FF Android browser, with the phone held "normally" i.e. longest side of phone held vertically, and I press the little icon in the corner of the video to make it "full screen", the video ALWAYS, ALWAYS, ALWAYS, rotates 90 degrees, which I dont want it to do. I hesitate to call this "landscape" because I'm not rotating the phone.

This behavior is unaffected whether in auto-rotate mode, or portrait mode. Chrome does not have this issue. My phone is a samsung galaxy A12, Android 11, latest FF browser.

Hi, I am using Firefox Beta for Android on my android phone. Its OS is Oreo (Android 8). Since Firefox Beta for Android 118.0b2, There is no audio on any website in Beta & Nightly. Firefox Stable and other browsers work just fine. Videos or online audio players work but there is no sound. I tried deleting cache, resetting the app and uninstalled and reinstalled the Beta and Nighty but the problem persists. I have searched online for help but I couldn't find any similar complaints. The audio on my phone works just fine. There is problem only in Firefox Beta (& Nightly) for Android. I don't have any extensions installed. I need your help. Thank you.

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.

The power draw can be heinous. In 37 minutes of use so far for this full charging cycle, it has used 5 times the power (measured by Android's battery page) as RedReader has in its roughly 2.5 hours. Is there a way that can be brought to heel a bit?

I used the Firefox mobile app for a while now and I noticed a high battery usage from it. If 10% of battery gets drained during the night, at least 75% of that is used by Firefox (according to the battery stats of my Pixel 6)

Is it possible to slow down the background sync or maybe dont sync at all during the night if the phone is locked?

Thanks.
