एंड्रॉयड के लिए Firefox Community Forum

Firefox on Android freezes completely whenever I open multiple tabs.

Steps to reproduce:

Open the Firefox app on my phone.

Open a website in one tab.

Open a second or third tab and try to switch between them or browse.

Observed result:

The browser stops responding, freezes, and fails to load or switch tabs smoothly.

Expected result:

The browser should handle opening and switching between multiple tabs without freezing or crashing.

On android ff app is killing private tabs if focus changed for couple of minutes. If search or do a conversation with bot or ai, the page getting refreshed to start of conversation. I removed battery saving or restriction on android origin os 15

Hello, I run Firefox mobile on a Motorola g stylus 5g, and although I'm aware it's a lower-end device, the constant crashes with the app is becoming infuriating. I'm on the newest version, and a large majority of these crashes occur when I'm on twitter browsing posts.

These crashes can happen a few minutes into browsing to an hour, and this issue used to never happen until the update before this one. I use a few extensions related to appearance, those being Ublock origin, dark reader, and control panel for twitter. Performance regarding being on the website has always been awful, but it's never crashed before.

In addition, the app is insistent on reverting me to tabs I had either an few hours ago to days ago, and it changes to what I currently had on screen for unexplainable reasons. I've tried resyncing tabs but this rarely solves the issue

Any advice in resolving these crashes would be appreciated. Attached is my crash log.

Dear Firefox Team,

My tablet (Lenovo P11 running Android 11) crashes completely (as in completely freezes not allowing me to do anything else), when opening certain websites (1 out of 3 times) including but not limited to instagram.com profile pages. I believe crash reports were never sent or could be sent, as my entire device has crashed.

As for more I formation, I had these extensions running: 1. U-Block origin 2. ClearURLs 3. Dark Reader 4. Video Background Play Fix 5. Chrome Mask (but was deactivated mode)

This crash happened 5 times now (out of the 10 to 15times I have opened these sites).

I have for the time being installed Fennec (with only Ublock, clearurls extensions running). There has been no crash yet.

I would like to confirm why those crashes were caused. Here are some of the reason I believe: 1. I am using an old Android device. 2. I was using multiple extensions incompatible with the webpage. 3. Combination of both.

If there could be other reasons please do state them.

Running Firefox Android on a Samsung Galaxy Tab S6 tablet running Android 12. Using Firefox version 153.0.4 (Build #2016177879), 54be19de0e08edff0b797e55fd935dd3978b0a6d GV: 153.0.4-20260810162159 AS: 153.0 OS: Android 12 Also using a Fintie bluetooth keyboard. The keyboard shuts off when not used for couple of minutes. When I need it I tap the keyboard to bring it back but then Firefox crashes and needs to be restarted. How can I fix this?

Yeah already reset it once, lost all of my passwords,bookmarks and anything else you said let me keep these so you can restore your browser if something happens...YOU did not say they would be restored if YOU messed with the browser and screwed things up! IT DOES NOT WORK NOW! So these question and answer games are just a waste of time and for you to play little games, Will look for another browser that I know works!

I want to use Firefox on my foldable phone alongside several other apps. However, Firefox won't stay open in split-screen view; it only runs in full-screen mode and closes all other apps. That’s a real shame. If Firefox can't be adapted to work this way, I'll have to use a different browser.

Hello,

I've been having an issue where Firefox Android keeps crashing whenever I tap the address bar. This happens when any tabs are open (even just 1) and even when I try to open a new tab to try and avoid the crashing.

The issue is consistent and repeatable for almost a year now. Thought updates would fix it as this issue was reported before. However, even after multiple updates, clearing the cache, uninstalling and reinstalling, and disabling all extensions the issue persists.

This is also not just limited to the address bar but also happens when I try to change the search engine from the quick switch on the address bar, search my bookmarks, history and settings, and sometimes when even trying to type into a website. While typing this post I backed away, closing the keyboard, when I clicked back into the text box to type the app crashed.

The only way for me to type in an address or search for something is to close all open tabs and then type into the address bar. Even a single open tab causes the app to crash repeatedly.

Hello, Firefox keeps crashing numerous times everyday, I've just uninstalled it then reinstalled it and within minutes another notification it's crashed, works fine on my pc and been using it for years.

I've been using Mozilla browsers since Mosaic, when I built netsys.com, delta.net, inetexpress.com and Damocles.com.

I'm trying to login to many sites which send a text message to my phone... But 80% of the time, my Firefox web browser refreshes.

I'm using android 13, 1/1/26 release on a moto G play with all background operations disabled, battery saver on...

Even if I allow Firefox to operate in the background... It doesn't matter.

Firefox for android keeps crashing period open it up and in a few seconds it'll crash and it just keeps doing this period

Also comma when I sync it with my computer, it syncs everything but the bookmarks

everytime i use google slides, it lags to the point i can't exit the tab or close it, i either have to force my pc to restart or wait for it for crash. and this only happens on slides, every other site is fine. i thought it could have been me having multiple tabs open but I've tried with only one tab open and slides still crashes firefox. and with multiple tabs, it's only slides causing problems.

My Firefox browser is crashing automatically on my Android device. Whenever I try to open the browser or load a website, it closes suddenly without any error message. I have already updated the app, but the issue is still not solved. Please help me fix this. Thank you.
