Форум поддержки Firefox для Android

Steps to reproduce : - go to YouTube - open a video - press the full screen button or tilt the phone sideways to trigger full screen - Firefox crashes and forces back to home screen - if opening Firefox again only half of the video component shows as in portrait mode, rest is black screen - if attempting to go side/full screen does properly show the video, but going back again to normal screen still shows the half black screen

I can reproduce this with a almost 100% rate, it only fixes itself by restarting Firefox, where it will work until phone is put to sleep mode.

I tried reinstalling Firefox from scratch, as well as deleting my browser cache and it didn't fix.

Every time a youtube video is placed on landscape mode on the firefox app of my android phone it becomes a single blurred image with the audio playing as normal.

Youtube seems to work fine on other browsers and I have tried all basic fixes, like deleting cache/data/reinstalling app etc. Appreciate any help.

Edit. Okay I managed to fix the issue so I'm adding the solution here in case anyone runs into this problem. Apparantly youtube playback decided to enable "ambient mode", a feature I didn't even know existed and seems to not play well with a phones resolution.

Just click the settings gear while the video is playing in landscape (mine is on the top right) and disable the "Ambient mode" feature.

Hope this helps.

I am trying to set the home page on my Samsung S21 with android v13 and firefox v117. I cannot find any means for setting the home page. The customize homepage in the top (3 button) menu has no option for setting a different home page.

The homepage option under settings gives you exactly the same options as above.

The customize option under settings applies only to the theme and has no options for managing the home page.

Unfortunately every version of firefox is different and all the instructions I have found apply to different versions of firefox than the one I am using.

Sometimes when I click full-screen on a video, the app view disappears, and I am back out on the home screen. I still hear the video, and can switch back to Firefox and try full-screen again. It usually (maybe always) works the second time.

When it happens, I can briefly see the video go full-screen and rotate to landscape. When the view has disappeared the screen rotates back to portrait. Whenever a video stays in portrait mode when going full-screen, the problem does not occur.

Even when closing firefox, I can still hear the video. So I think it is related to this issue: [https://support.mozilla.org/en-US/que.../1420245]

What I have tried:

• Switching versions of firefox, they all have the same issue; Firefox, Firefox Nightly, and Fennec.

• Clearing cache and disabling add-ons has not worked, but seemed to make it happen less frequently for a while (not sure).

• I tried activating automatic screen rotation, but this made the problem worse. It would then not work the second time and firefox would only display part of the website in the top right corner of the screen. Closing it and re-opening it multiple times did not work. I had to turn auto-rotate back off.

• I'm using the KISS launcher. Tried switching to various other launchers, but it made no difference.

OS: Calyx OS 4.12 HW: FairPhone 4 Firefox: Fennec v116, Firefox Nightly Add-ons: uBlock Origin, Tampermonkey

Recently autofill has stoped working, i get suggested login, address, credit card and tap on it, yet it doesn't populate the fields, tried turning on and off sync and still doesn't work

When logging in to any app or website, instead of my saved log in info(username, password) popping up or being auto-filled, I get a button that says "Unlock Firefox." Tapping or holding the button does nothing. How do I disable this "feature?"

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.

HELP! My mobile data usage spiked as of June 20th and has continued at unprecedented levels almost every day since. My historic daily usage for the past many years has been around 4 MB and is now 95MB. and busting through my 2GB/month limit. This is ALL due to Firefox! What happened? Something strange happened on June 19th, when my mobile date usage recorded three separate usage figures instead of the single usage figure for all days previously. June 19th showed 2 usage figures and June 30th showed 3.

When I try to install it from the Mozilla add-ons site the button to "Add to Firefox" is inactive and there is a link to download the file (which Firefox cannot open). The add-on is supposed to be compatible with Firefox for Android version 48 and up. I am using version 114. Previous versions of the add-on could be installed. web-ext lint doesn't show any incompatibilities.

Firefox Mobile is the only major browser that I am aware of that does not support FIDO2 U2F logins. I have seen TONS of requests and complaints about it not being supported, with the general answer being "tough s**t, deal with it." If Firefox cannot adequately support industry standard security practices it should be removed from the market. Using Firefox on Android explicitly reduces the amount of security your sessions have vs Chrome or Edge due to the failure of this feature to work. Firefox on Android is basically useless from a security point of view. Fix it or discontinue it. You either need to embrace security standards or stop making browsers.
