Firefox for Android Community Forum

Hello, Sometimes my browser is not reponsive when i open it. There is no apparent reason for why it does this. It doesn't load the last opened pages and does not load when i type a query. I have to reboot it several times sometimes before i can use the app again. This is not a major issue as i just use another browser in that case but you can consider this information as a datapoint for "potential bugs". This is exclusive to the app and not the browser.

Happy surfing :)

I am a big fan of firefox but i see some difference between firefox and chromium based browser that is Smoothness. All those scroll and swipe are beautifully smooth on Chromium based browser but in Firefox, it stutter and feeling visual lag. I know that Firefox is made by different engine but on IOS it's feels smooth but on Android it's sluggish. I hope you guys find a way to fix those problem.

Occasionally (it already happened three times today) when i'm browsing and switching between tabs, one tab will become an image of its contents (as in - no links work, can't scroll vertically or horizontally) and the others become grey. Trying to reload the pages or open new ones doesn't work, they never load. Turning the browser off by going to the phone's home menu and closing Firefox in the recent applications view doesn't solve the problem, it only closes any private tabs but the issue persists when opening any new tab or preexisting ones. The only way to fix the problem is by force stopping the app. I've cleared the cache, it didn't solve the problem, and reinstalling seemed to work for a few days but now the problem is back. For reference, my add-ons/extensions are: Ghostery, NoScript and UBlock Origin.

I use the NFC on my phone in order to tap onto a bracelet that gives me a daily scripture. It was working but the past few weeks it either doesn't download, is super slow and only may or may not load the whole thing. Once I uninstall and reinstall the app on my phone it works great. Sometimes it may work a day or even up to 3 days, but lately I'm having to uninstall and reinstall daily. Then I have to customize everything again. It is the same with webpages loading also. I clean the cache regularly and I've checked my internet connection and it's fine. Hopefully, this issue can be resolved. I'm using a Samsung Galaxy A52. This is only happening on the phone and although I can't use the bracelet on my laptop, I don't have any issues with Firefox. Should you need any additional information please let me know.

I used camera inside a tab and then closed the tab. I get the "Tap to open the tab that's using your camera." notification. If I tap it redirects me to home page in Firefox. If I swipe right or left won't close the notification (seems to be glued).

It's the second time I'm confronting this. It disappears only if I restart the phone.

When switching apps from Firefox to other apps, it almost always reloads the webpage. This is annoying in the certain scenarios

1. After I enter my username, it goes to a password page. I switch app to my password manager to copy my password. Comes back to Firefox and it refreshes, going back to username screen. Impossible to login. 2. After I enter my username and password, I need to go to SMS or Outlook app or Authenticator app to obtain the MFA code. Comes back to Firefox and it refreshes, going back to the login screen. Impossible to login.

This happens to various websites. I have no issue with Chrome or Brave on the same phone. I even tried terminating all apps leaving with just Firefox and the same symptom happens. Memory is sufficient, my phone has 12GB of RAM.

Frequently when switching tabs or opening the app to start a new search, when I've typed in my URL or search, it just hangs on a gray or black screen. Eventually the page does start loading with the rainbow progress bar and the page loads.

I've turned off extensions, it doesn't seem to be that.

Often when I type in the search bar I experience different bugs. Either the cursor will jump around while I'm typing and make it difficult to properly input my text, or it won't register that I'm hitting enter/return, or it won't even type anything until I refresh the page (this one is the rarest and has only happened a couple times)

This started happening the past couple months, so I imagine it's due to a recent update. It also only occurs on my phone and isn't the only reoccurring issue I've experienced while using the phone browser. It often fails bugs when scrolling and requires a refresh to show everything on a page or a complete restart of the app.

I am sticking with Firefox but these constant issues and others due make it frustrating.

After opening Facebook in the firefox browser for android, I am not able to comment on any Facebook post. The keyboard is not stable. Please fix this. And when I download any big file, it fails after half the download. This process happens again and again. Please fix this. Thank you.

There is a significant delay with URL suggestion autofill when writing an address/URL into the URL-/search field. Many times resulting in a web search of the incomplete URL name, instead of going to the correct page. (Oneplus 13)

​I am reporting two visual glitches (white bars) occurring in the Android version of Firefox.

1. White Bar Appear Numbered list items at the Top in Portrait Multi-Select Mode
   When the browser is in portrait mode and I enter the multi-select state (e.g., in the Bookmarks or Downloads management screens), a white bar appears briefly or persists at the top of the screen. This seems like a UI rendering error.
2. White Bar Appears on the Left Side in Landscape Mode
   When the phone is in landscape mode, a persistent white bar/strip is visible on the far left side of the screen. This affects the full-screen display.

Hi , Recently Mozilla started behaving problematic, I wonder if this problem is persistent in every Android device. When I switch apps on mobile let's say I open a banking app to copy paste credit card information and then reopen the Mozilla from the recently used application tab/section. Mozilla gives a black screen in which only bottom frame where the address bar and navigationonal buttons are placed is visible. It sticks there for 10-20 seconds, and then the web page appears or I have to refresh the page.

It s quite annoying and you have to wait a lot, lose the latest info on the page as you have to refresh it. I don't know if there is any solution to that or is it because of my Xiaomi resmi note 13 pro plus.

Hello Firefox Community,

I'm hoping for some help with a persistent video playback issue on Firefox for Android. I am committed to using Firefox for its privacy and its independent Gecko engine, but this performance bug is a major blocker.

The Problem: When I play videos in Firefox, the playback is very choppy and stutters, appearing as if it's running at a very low frame rate.

Crucial Testing Information:

This issue is specific to certain browsers. I have tested the exact same videos on Chrome, Vivaldi, Brave, and Ulaa, and they all play perfectly smoothly. The stuttering issue happens in Firefox (and also in Opera).

This confirms the problem is with how Firefox is rendering video on my device, not a network or hardware limitation.

Troubleshooting Roadblock:

I have already tried all the basic fixes (clearing cache, reinstalling, etc.).

I attempted to follow standard advice to troubleshoot this by accessing about:config to check the status of hardware video decoding. However, access to about:config is completely disabled in the stable version of Firefox for Android. This prevents any advanced user-side troubleshooting for performance issues like this.

My Device Information:

Phone Model: OnePlus Nord 2T

Android Version: Android 14

Firefox Version: 143.0.4

Given that a critical troubleshooting tool is unavailable, I am reporting this directly. This seems to be a hardware acceleration incompatibility issue with my device.

Any help would be greatly appreciated. Thank you!

Where is the issue tracker for Firefox Nightly on Android? The last few updates have caused the keyboard to block the bottom part of webpages, making it impossible for me to see what I'm typing.

In the first loading the share menu would only show other firefox devices until a few seconds later other options appear. Closing the menu and reopening would not have this problem so I am unable to check if it's an Android problem
