Firefox for Android Community Forum

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 now have the problem that I am on a large payment page and switch back and forth between FF and another app (to copy payment-relevant data). Unfortunately, FF does a page refresh every time it is brought back to the foreground from the background. And all the data already entered is lost! This is a fairly well-known problem with FF on Android! Chromium manages this better and leaves the memory management to Android. Why can't FF do that? Why can't I switch off this feature? I can't edit any relevant websites with the FF. I have to use Chrome for that! Hooray!

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.

I have a Blackview Tab16 (10" screen), which I bought last year; it was running Firefox quite happily until a couple of months ago. Now when I click on the icon, I get a sort of 'welcome' screen (with some message about a search widget?) for a fraction of a second, then FF closes and I get an error message saying 'Sorry. Firefox had a problem and crashed.' The version of FF is 126.0. I was told to try clearing the cache, but there is nothing there to clear! The tablet is running Android 12 / DoKe OS V3.0.

I have an 8" Blackview tablet which - despite needing to be plugged in to run all the time! - opens & runs Firefox perfectly happily. It's my main browser on my MacBook as well, and will run on my iPhone.

Hello

On some website (example : https://tasmota.github.io/docs/Commands/ ) the "find in page" search field will just vanish in the middle of typing or while pressing the up/down arrow to go through findings.

Firefox version : 131.0.3

Hi,

Since I've installed the latest Samsung OneUI6/Android 14, Firefox keeps crashing randomly. There was a firefox update after (120.1.0, build #2015989146), but same behavior. When opening accessing a new url (either new tab or existing tab). No message displayed, simply closes. Everything is up to date, non rooted galaxy S23 ultra with Android 14/OneUI 6. Already cleared firefox app cache, uninstalled and reinstalled (this worked for a few hours, but it's back to same behavior).

Any ideas?

Hi, I got a problem since many weeks on Firefox Nightly, the elements on websites that should stick to the bottom float around 30pixels above the bottom. It's kinda annoying. My app is up-to-date. I got a Huawei P20. Thanks Elise

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!

When switching to another app from Firefox and then switching back to firefox, the webpage reloads. This is not a memory issue, I have enough RAM and it happens even if I only have 1 tab open. This is a major pain when I need to enter a 2FA code and need to swith apps to get the code. Or if I'm watching a YouTube video and get a call, the youtuve page reloads after the call has ended. Please suggest how to fix this.

When I tapped on the firefox widget on my phone this morning, it showed "google.com" in the address bar but the page was blank. I checked this on my wife's phone and my tablet and the exact same thing happens. I tried turning off my two add blockers to see if that would make a difference but it did not. I then uninstalled and reinstalled firefox on my phone from the Google Store and logged back in and it still acted the same way. For fun, I then turned on "Desktop site" in the menu and then my normal google.com page opened up. When I turned off 'desktop site', it went back to a blank screen with the "home" icon, the address bar, number of tabs open box and the 3 dots menu bar showing on top, but nothing else. I then opened my computer and works fine on my desktop. So, not sure what is happening but definitely some problem with "google.com" address on firefox (unless I toggle on "desktop site".) I also cleared my cache (which of course, was completely empty when I deleted and then added on the firefox app at the google store). Seems like might be a problem on your end? Especially since seems to happen on all four android devices that I have. I've also attached screenshots of the two pages I get, the first regular, the second with 'desktop site' toggled on.

For the past few months, videos on YouTube haven't been playing properly. They load just fine and there's no issues with the auto, but once the video starts playing it will sometimes be zoomed into the top left corner, making it impossible to properly see what's going on.

This happens with music videos too, both official and lyrical. It will be zoomed in close to the top left corner and just barely catches what's going on in the video. Sometimes, video do play like they're supposed to, but for the most part, they'll be zoomed in as soon as I hit play.

When I try to enter a password for any website after a few updates ago, I don't get the option to enter my password that's saved in my password list into the fields anymore. I have to manually search, copy, and paste the information in. The app will then ask me if I want to update or modify the login information that is unchanged from what should already be in my browser.

Regardless of whether I say yes or no, the password remains unselectable when I go back to that website, and when I manually enter the information, it again asks me if I want to update the login information.

Recently firefox for android mobile stopped allowing me to take screenshots. I get the error msg in the subject line when pressing the volume down and screen sleep/wake button. Is there a setting I can change?

I encountered a problem occurring under LineageOS 20 (android 13) on a Sony ZX1 Compact. Can't check if it's the android version or just something with that Lineage ROM (which works perfectly with anything else):

When I make a PDF of a web page with Firefox and then just press "view", the pdf viewer says the file doesn't exist, even though it was saved correctly to the Download folder. Choosing Firefox itself as pdf viewer, I could determine that the viewer gets a file link like this:

content://org.mozilla.firefox.feature.downloads.fileprovider/Download/Download/Kanaren-Wetter%3A%20Sturm-Warnung%20zum%20Wochenende%20ausgegeben.pdf

Which appears to point not to the real Download folder, but perhaps to Firefox' subfolder in the Android/Data folder? The same link is given in any other OS, and normally it always works. Could it have to do with the fact that in LineasgeOS 20 (and quite surely also stock android 13) the Android folder is write protected ?

With some web pages, Firefox provides different links, like: content://media/external_primary/downloads/1000009015 and with those there's no problem. So I think may really be an issue with directory access.

I fiddled around a lot with OS settings and Firefox beta's about:config as well, but to no avail. Also de- and reinstalled Firefox.

Any idea what could be the cause ?

Hi. For the past few months I have been unable to play any samples from the Audible website in Firefox on my android phone. When I click the word "Sample" Audible opens up a new tab with their Web player and I always get an error message that is just a rectangular box with an exclamation mark inside a triangle on the left side of the box. (Screenshot attached.) There are no words inside the box and the only option is to close the tab. Since there is no actual message I'm not sure what the problem is.

Here's a link to the page visible in the screenshot: https://www.audible.co.uk/webplayer?asin=1445081911&contentDeliveryType=Unknown&isSample=true&ref_=a_pd_jpp_cloudplayer_1445081911&overrideLph=false&initialCPLaunch=true

Playing samples used to work fine when you could play them within their web page before Audible changed its system. I seem to be able to play samples on Audible's Web player in Chrome, but would prefer to keep Firefox as my default browser. I have tried deleting all history, cookies and cache; closing and reopening Firefox; turning phone off and starting again after an hour. I've also tried enabling autoplay, but that made no difference. I was thinking that the issue may be with my other settings within Firefox, but I can't tell. Any help you can provide would be great. Let me know if you need more info. Thank you!

(I'm in the UK. I don't know if that makes a difference, but I don't see a UK specific forum. Thanks.)

I'm using a Huawei P20. I've been using FireFox for a long time mainly for accessing YouTube through the browser. After recent updates when I try to play a video it always appears to be really zoomed-in and completely unwatchable, decided to switch to WaterFox to resolve my issue, but after the last update WaterFox also has the same issue.

Can anyone provide some help with this issue?
