Firefox for Android Support Forum

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.

Nothing will load in my browser after an Android update to my phone last night. All pages that I was viewing yesterday on different tabs remain gray--no error or other indication of how to fix this. Chrome and Incognito load the same pages without issue and work fine.

I suspect the issue was introduced with the Android update to my phone last night but not sure.

All web pages in Firefox for Android and blank, just a white screen. Send like the same issue others have reported recently, but unlike them v114.1.1 has not fixed it. It may even have been when it started though I'm not sure about that.

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.

Firefox on my android phone (OnePlus Nord N200) won't load any web pages and there is a red line across the lock icon in the address. This is happening to any web page I try to open. I am not getting any error messages and the browser home screen shows my open tabs. When I click on them (or if I do a new search) all I get is a blank page and the address with the red line across the lock. No problem with Chrome, nor with Firefox on other mobile devices.

I'd been running Firefox nightly on my Samsung Galaxy S21 with virtually no problems for ages, but suddenly and randomly early today, the app crashed in the background while I wasn't even using it. And since then the app refuses to work and instantly crashes any time I click the app or try to open a link with it. I've already tried rebooting my phone, changing the android system we view, clearing my firefox cache, clearing my Firefox data, and uninstalling and reinstalling the latest version of the nightly app and it still just crashes immediately. I'm completely baffled as my regular Firefox app still works fine, it's only the nightly build that stopped working.

I pay my fees from mozile firefox but the page get refresh n fees receipt is not generated but the amount of fees will be debited from my bank account what should I do

Every time I open a video and Firefox the stupid media control opens on my phone and plays the video or music or whatever I clicked on in the background for eternity unless I pause it, but then after a few minutes it just starts playing on its own again. Why is there no option to disable or close the stupid player?

I close Firefox I end the process but yet the stupid sound keeps coming out of my phone even with the screen off all the apps closed.

The only option I have is to hide the media control which then plays the music with absolutely no way for me to stop it. If I click on settings from that window it brings me to a screen where both options are already disabled saying not to use it but it's still opening anyways.

I can only find remedies for Windows or Mac I have not come across any solution for Android. I basically have to restart my phone every time this happens in order to get it to stop.

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.

Since I installed the last update, no pages load (see attached screenshots). The URLs are displayed correctly, but pages are neither trying to actually load nor displaying anything, they are just blank. The padlock symbol is crossed in every tab, but I'm not sure whether this is actually a difference to when it was still working. Clicking on its symbol does nothing.

Checking every function in the app: - No pages load, neither in normal nor private mode, neither do bookmarks, links nor formerly open tabs. - The settings are all accessible, changes made there actually apply (like enabling screenshots in private mode) - The Add-ons menu loads indefinitely, and trying to log into firefox account does nothing (with QR code) or redirects to an obviously blank page.

I did: - Force the app to stop. - Restart the phone. - Empty the app's cache.

I haven't tried reinstalling the app, but all my bookmarks would be lost (since logging into my account also doesn't work). Assuming my problems are due to a bug, this wouldn't work anyways.

Thank you for your time!

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 text size in Worldle all of a sudden got very small. Same thing happened for two other word games I play. The problem doesn't happen in chrome. Did Firefox change the code? I've tried to enlarge the font but it doesn't help with the font inside the games' graphics. Appreciate any advice!

Hey there,

As the title suggests, I'm having an issue with the navigation bar. It remains at the bottom of the screen even when I have the least need for it, which makes the content of the screen glitchy. It may not sound like much, but it's very annoying and ruins the whole browsing experience, especially when watching videos. Because of the unwanted navigation bar, even a slight touch on the screen causes the videos or pages, but mostly videos, to move around left and right when in landscape mode. As you can see in one of the screenshots I sent, the video is not even visible, it's just a black screen, which is a different issue that I faced for the first time but I am not sure how often I'll get that in future but it's there.

If anyone can suggest a fix for this issue,(the one with the navigation bar and jumpy video screen) such as a setting that I can turn on or off to get rid of the navigation bar, it would be greatly appreciated.

Just updated to latest version of Firefox for Android (ver 113). When I try to watch a YouTube video in full screen, the app suddenly closes, as if I pressed the home button (note: I say "close" rather than "crash" because when I reopen it, all the pages are still loaded). This doesn't happen every time, but it is annoying. Is there any way to fix this?

Hello, I'm writing to describe a recurring problem I'm facing while using Firefox on my Android device, and I need your help to find a solution.

The issue is that my tabs keep getting accidentally deleted when I scroll up and down. The touchscreen on my device is highly sensitive, and simple scrolling often triggers the "left or right swipe" action, causing the current tab to close. This is incredibly frustrating as I like to keep my tabs organized, and having to reopen them repeatedly is time-consuming.

I've tried looking for a solution in the Firefox for Android settings config:about, but I haven't been successful so far. Is there any way to disable or adjust this feature so that left swiping no longer closes my tabs?

I'm a dedicated Firefox user and would like to continue using this browser, but this problem is significantly impacting my browsing experience. I would greatly appreciate it if you could provide me with a solution to this issue.

Thank you in advance for your assistance!

Best regards, Denise

When attempting to enter full screen mode on Firefox for Android, and to get into landscape mode, the browser appears to crash, keeps audio playing, and "entering full screen mode" dialogue pops up. Have to open Firefox again, and can only be viewed in landscape mode while session is continued. To return to non-landscape mode, the app needs to be force stopped, otherwise you only get to see the left one third side of any web page you navigate to. Seems to have started with most recent update. Is there any way to fix?
