Firefox for Android Community Forum

I'm having a problem with playing videos on websites. When I click the expand to full screen button about half the time the full screen video comes up for half a second and then the window shrinks down to a small square on the bottom right-hand corner of my screen. Sort of like when the youtube app minimizes a video. This window is unclickable and also everything at or below it in android is unclickable while it's there. If I click the window button on android and swipe the firefox app up to close it and restart it, Firefox doesn't even close and I can still hear sound from the video. I have to select on the Firefox app again which will restore the full window and then click the full screen button one more time and it will work. This issue is happening on every website I play video on on the Firefox app and it is extremely irritating. I'm about ready to switch to another app if this can't be solved, but Firefox is the only browser that allows ublock origin so I don't want to do that. Can anyone help?

Whenever I enter fullscreen mode, the entire app minimizes itself and starts playing audio in the background. I have to reopen the app and reenter fullscreen in order to actually use fullscreen and it is extremely frustrating. Is there anything I can do to fix this?

Firefox on my android phone times out on any webpage whenever I am not connected to a Wi-Fi. All webpages and IP addresses timeout with no response. Same issue occurs on Firefox Beta app and Firefox Nightly. All other applications work as expected with full internet access on mobile data. The same pages/addresses respond as expected on Chrome and the built-in browser.

Simply put, all Firefox apps have no internet connectivity on mobile data.

Solutions I've attempted with no success or change: Re-install Firefox. Logging out of Firefox Sync. Clear Firefox data and cache. Disabling tracking protection. Disabling HTTPS-only mode. No proxy settings are enabled. Confirmed Firefox application has mobile data network privileges. Disabling, re-enabling mobile data network privs. Installing Firefox Beta and Firefox Nightly; same issue.

Another possibly related issue: Firefox does not follow routes from a Cisco AnyConnect VPN on my phone. Opening pages/IP addresses routed through the VPN are rejected or timeout as if the VPN is not active at all. The same pages/addresses respond as expected on Chrome and the built-in browser. This occurs over Wi-Fi as well, of course nothing works on mobile data as described above.

Device: Oneplus 8T (KB2003) OS: OxygenOS 13.1 (Android 13) Firefox version: 117.0.1

Firefox for Android is non-responsive on my Samsung flow HP PC screen. Please advise. All other browsers are responsive. Love Firefox thou, but can't use it on my PC (Samsung flow screen on the HP PC.)

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.

Hello,

On Firefox for Android, I get "Proxy is refusing connection" error while attempting to connect to any site on the Internet. But I didn't configure any proxy connection for Firefox! Moreover, this error happens when I use my home Wi-Fi network, but browser works properly when using cellular data or any other Wi-Fi network. Also, browser works for some time if I start VPN (Psiphon in my case), stop Firefox through Android settings, clear cache and start the browser again.

Best regards, Peter

I think the virus is back, it interferesbwhen typing, it's stopping my smaller antivirusles from working properly, it keeps turning the VPN off, it's blocking my internal and using my pin card! And I'm blocked from my Amazon account because chrome went to buy something! I've had this virus before so you must have a report number about it, it's very clever but I'm fed up fighting it now, been going on for months and theres nothing wrong with my phone, but starting to think about getting another, this annoys me every day!

Going to full screen on YouTube (and other video websites) usually breaks the Firefox app on pixel 7 pro. It keeps playing but just closes and can't be reopened. I have to stop the app, open it again, and try again. Does anyone know how to fix this?

When I am watching videos in the firefox app, about 70 percent of the time I go fullscreen to watch the video, it will close the app. Not crash, but leave, like I'm hitting the home button. This has been going on for a long time now. Last time I asked for assistance I got "Have you tried closing your other tabs?". I have 12 tabs open. I never have this issue with any other browser. I have 30 tabs open in chrome, with no issues.

(using 118.2.0) At times the navigation icons and the reload icon disappear from the task bar. When I go into Settings and then back to the browser page the icons are gone. They are still in the "3 dot" menu. The only way I have found to reappear them is to close the app (go into android task list and "swipe" it closed) and reopen it.

Any ideas/suggestions?

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

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.

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.

After selecting Mozilla as my default browser, I tried to perform a search but the only page that loads is the page that wants you to download Mozilla on desktop and android, which I already have. Each time I've tried to do a search with Firefox this is the page that appears, no search results of any kind, but when I switch my search to duckduckgo and perform the search I get results. Can someone please help me understand why I can't perform a search using firefox?? Thank you in advance for your help!

Hello!

Firefox on Android won't display pop-ups. I've checked privacy setting but there's no checkbox for a popup blocker. Also tried about:config but didn't find any setting to change. Any ideas on how to be sure Firefox is comfigured to allow popups? I participate on a Zoom webinar and can't start Zoom through Firefox so have to use Chrome.

Thanks!

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.
