Firefox for Android Support Forum

YouTube videos on Firefox Android Stable, Beta, and Nighty, experience significant frame drops when viewing "Stats" both on AVC1 and VP9, and on all resolutions. I checked about:config in both Beta and Nightly and HW acceleration was enabled. This was true for a FRESH install as well. I tried this on other devices and the problem persists. Mull, which is a fork of Fennec, plays the same videos without any problems. Other browsers are also fine.

Tested on Samsung S20 One UI 5.1 (Android 13). Tested on Samsung A13 One UI 5.0 (Android 13). Tested Sony Xperia XZ2 Compact (Android 10). Tested on Sony Xperia XZ1 (Android 9).

Some text disappears on both Firefox and a Firefox Focus on a CAT S22 Flip phone. I am able to glimpse at the text by long-pressing to evoke the menu. Please see the demonstration video linked here: https://youtube.com/shorts/ZxKtVFrvQkU?feature=share

I noticed that on a regular basis, Firefox Android slows down dramatically after 1 or 2 hours of browsing. The only fix of the problem is to force stop the browser and launch it again. This happens consistently as well after disabling extentions. Firefox is updated to the latest version, 110.

Dear support team,

I am experiencing a problem with one specific website, zerohedge.com. Whenever I use the back button to return from an article to the home page, the page appears completely blank, and I am forced to refresh it every time. This is happening on the Android version of Firefox, version 111.1.1 (Build #2015941331) with NoScript and PrivacyBadger add-ons installed.

I have not made any changes to the settings, and this problem has only started occurring about a week ago. I have never observed this behavior before.

I'm having an issue with Firefox on Android. On certain websites (e.g., Yahoo News, Calscape.org, Google search results--with Goggle Search Fixer add-on enabled), I can scroll down the page without issue, but scrolling slowly back up toward the top of the page with downward drags of my finger is only responsive half of the time. That is, I can only scroll back up with every-other downward swipe/drag of my finger. This odd behavior does not happen with other mobile browsers (I'm on Android 13 and using a Galaxy A53 5G). Any suggestions?

Firefox Android just crashed when opening a bunch of bookmarks and then again every time I wanted to report a crash. I hope someone here can forward this to whoever usually receives the crash reports.

Keep seeing a bug where tabs that were kept open but are not active, upon reopening do a full reload, and then take a long time to load often failing to load at all after a timeout.

I have the problem that Firefox does not correctly recognize when I want to scroll up on a web page. This often causes me to accidentally refresh the page. Usually this should only happen when I'm already at the top of the website and then swipe down again and not in the middle of the website. I have even tried Firefox Nightly and Klar, but the issue occurs with every browser. Is there perhaps some trick or hidden setting that causes the browser to scroll reasonably again instead of constantly refreshing the website?

Firefox has been crashing my phone for a while now. It finally was able to generate a crash log. Can someone take a look at the log and see what might be causing it? Thanks.

I downloaded Firefox vpn for Android, but when I try to sign up and sign in as a guest I get an error message saying invalid API key

I can no longer send e-letters, though I can receive them. "Send now" has been replaced with an icon resembling a pen balanced diagonally, i.e.: "/", but pressing on that icon gives no result. What must I do to be able to send e-letters again?

Thank you for your attention in this matter.

Hi. Around the last few days of July the videos on Youtube started freezing like when they stop playing to load, except it never stops loading and continue the video. When I skip ahead it plays for a few seconds and then stops again. I tried playing videos on other sites, and the same thing happens. The Youtube app works perfectly, and so does the Netflix app and the Chrome app - so I know it's a problem particular to the Firefox app. I removed most of my add-ons to test and it didn't help (the only ones I didn't remove are the uBlock Origin and the Search by Image ones). Also tried uninstalling and installing the app again, but no dice. Any idea how I can fix that?

Happening on all platforms that I checked, from Youtube to Kick and several others. Basically the video just keeps on trying to load forever but never does, same behavior on all sites. Chrome is loading videos fine, other devices with Firefox are also fine.

Been using Firefox on Android for years with no problems. Wondering if this is my problem and I need to troubleshoot or if others are having the same issue, in which case I can just wait for Mozilla to roll up some update fixing it. All I did up to now is disable add-ons but the problem persists. I'll do a fresh install if I really have to but I'll wait for a response here first to make sure. Cheers.
