Firefox for Android Support Forum

Hi. I can't watch a video on any website after updating my android app to v.(126.0 I think) because it plays Stuttery and laggy. I don't have much tab open, mainly 2 or 3 and incognito mode doesn't makes any difference. Still videos play laggy as if it's on low fps. The recent update to v126.0.1 didn't fix it either. My phone is galaxy s21 ultra if it matters.

I can't remember when this problem started, but the volume dips down for maybe 1-2 seconds shortly after the start of anything with sound, like YouTube videos and MP3s embedded in a website. On the same phone with Chrome, the problem does not happen.

Has anyone experienced this? I made a screen capture that demonstrates the problem, alternating first with Chrome, then with Firefox (then both again) -- https://youtu.be/GB116jauaX4

Any help anyone could provide would be greatly appreciated!

for a recent update or two, when I am watching videos in fullscreen, at least like me, for example, when I entered fullscreen, the video should play horizontally, but after merely half a minute, the screen orientation goes back to vertical mode automatically, which is not happening when I began to use Firefox android months ago. Watching same website on different browsers, only Firefox goes wrong, so I think this should be Firefox's bug.

Hello,

I'm running Firefox on Android 13 (Phone is Poco x3 pro). Running version 126.0.1

As soon as I tab out of Firefox and go to another application, for example, a 2FA app or ProtonPass to retrieve a password, then go back to Firefox, the tab will reload.

This basically means that I'm unable to log in to any site which requires 2FA or where I don't know the password by heart.

The phone has 6 GB of ram and I've set Firefox to have no battery restrictions, yet it's not helping.

I don't know what's causing this, but surely this can't be intentional? I've had to go back to Chrome because I'm literally unable to log into most websites.

I've tried reinstalling but no change. I deactivated all extensions (ublock & privacy badger) but that didn't help either.

I'm uploading this on chrome.

The add function does not let me add photos or videos to any website requiring photos or videos for evidence. The "Add Photos (optional)" only says allow but does not upload photo. All permissions are allowed on Oneplus 12.

When I click on a web push notification in Firefox on Android, the link in the notification does not open. If no page is previously open in the browser, a blank tab appears. If another page is open, that page is displayed.

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.

As per the title, but only on a few websites, Firefox gets stuck in a neverending loop of trying to load. The page never shows at all, just a white screen and a rapidly moving loading bar at the top of the screen that gets 90% of the way across to the right then restarts.

I've tried clearing the cash, browsing history, opening the pages in incognito, etc, etc, nothing seems to work.

I am experiencing an issue where the Firefox browser on my Xiaomi Redmi 13C device running the HyperOS Android 14 operating system is consuming a very high amount of system resources, particularly CPU and RAM. This is causing my device to heat up significantly and draining the battery life at a faster rate.The specific problems I'm facing are: 1.Firefox requires special permissions and settings to function properly on my Xiaomi Redmi 13C device with HyperOS, such as exempting it from battery restrictions or granting it "autostart" permissions. Without these settings, the app crashes or doesn't work correctly. 2.However, when I grant these special permissions to Firefox, the app then starts consuming an excessive amount of CPU and RAM resources, much more than my other browsers like Chrome or Brave. 3.According to the system monitor, the Firefox processes are consuming the following resources: RAM 372M, CPU 39.0% Process "org.mozilla.firefox:tab12" RAM 742M , CPU 20.0% Process "org.mozilla.firefox" 4.This high resource consumption by Firefox leads to my Xiaomi Redmi 13C device overheating and the battery draining faster, negatively impacting the overall user experience. I have tried various troubleshooting steps, such as clearing the app's cache and data, using a lighter version of Firefox, and checking for updates, but the issue persists. I would appreciate if the Firefox support team could investigate this problem and provide any guidance or solutions to resolve the high system resource usage on my Xiaomi Redmi 13C device running the HyperOS Android 14 operating system.

Hello,

I'm not able to upload files to certain websites using Firefox on Android.

When selecting a file for the phone's file manager, the file upload simply not starting.

However, Firefox on iOS doesn't have that issue.

Firefox version used is the latest one and it is the one from Google Play.

Tried another browser and it works great.

Hi. I have to sign in related problems.

I can't Sign in to my work planning website: tjeps.g4s.dk/ESS/. It works fine on Firefox for Windows but on Android I get a new Sign in formular every time i try to sign in. Works on Chrome for Android.

The mandatory Authenticator app in Denmark for all public services "MidID" is not supported on Firefox for Android. Works on Firefox for Windows. This is a huge problem if you wan't Danish users. Also works on Chrome for Android.

I wan't to leave the Google Chrome browser but I am kinda forced not to.

Out of nowhere, the browser stopped when I was browsing and the pages started showing slowness. 👇🏻👇🏻👇🏻

I have had this problem on two separate midrange samsung phones now: after about an hour of browsing, firefox slows down considerably. Pages take a long time to load and tapping input registers erratically, sometimes i tap a link and after a few seconds a different link opens, as though the tap was registered from a different spot on the screen. This is happening even on a brand new phone, and after emptying the cache. I wish I could keep using this app because of privacy concerns but it is genuinely unusable for me now. This problem has cropped up in the past half a year

Firefox just used almost a GB by just opening it! I only typed a Google search, and the next moment my phone tells my I'm out of data!

Note that this is foreground data, not background data. I googled and found answers about media playing in the background, but I haven't watched anything recently, so no streaming link should be active. I installed Ublock origin so I hope that might help.

Attach is my Firefox data usage for the past week of barely using it, except for an occasional Google search.

Listening to audiobooks made me notice this problem, often whilst my phone is turned off and the audiobook is playing in the background on a tab on firefox the audio would just stop and i would find either that firefox was still open but unloaded all the tabs, or that it simply crashed. I thought this was a thing that solely happened when playing audio in the background but then i noticed that it is actually a general problem when firefox is kept open in the background. It doesnt happen after a set amount of time, sometimes it happens immediately, sometimes after like 10 minutes that it is kept in the background. How can i fix this? its very annoying.

Hi I have facing the problem with Android app, when I use the app very slow in 1 tab If I open another tab getting extremely slow then loaded the page not completed and some time suddenly restart My device specs Samsung galaxy A2 core

On my Android phone, the "close private tabs" notification keeps reappearing no matter how many times I tap it or swipe it away. Only way to get rid of it is by force stopping Firefox. Weird thing is that this issue doesn't repro 100% of the time either.

This is happening on Firefox 126.0, on my S23 Ultra running Android 14/One UI 6.1
