एंड्रॉयड के लिए Firefox Community Forum

Ever since I switched my search engine to duck duck go I've noticed that from time to time the firefox app deems to freeze up and either it continues or just crashes.

My mobile app Firefox keeps crashing on starting it reinstalling doesn't help it used to work at some point but now it doesn't.

My phone is OnePlus 13 it has the latest EU updates. I can't seem to figure out why it crashes.

I installed the latest version from the Google play store. Other versions of Firefox work fine like nightly or beta only the main one crashes.

When watching a YouTube video on Firefox while plugged into Android Auto and then unplugging the USB cable, Firefox becomes unresponsive. The video first pauses and if I try to play I get a spinning wheel. If I open a new tab and try to go to a website, I just get a gray screen. If I open recent apps and close Firefox and reopen, the issue persists. I cannot access any websites. If I open settings and select Quit Firefox, I'm stuck at Clearing Browsing Data... The only way to fix this is to open my phone settings and go to the Firefox app and clear cache.

To me this is a bug that needs to be fixed in the Firefox app.

I installed the Firefox update this week on my Motorola Moto G Stylus phone running Android 11. Since doing so, the app repeatedly crashes when I click on something in Collections. Bookmarks not in a collection still work, as do other links on the home page. I have restarted the phone, but it did not fix the problem. It is hard to avoid the confusion that this is being caused by something in the update. Will there be a fix released soon?

Hello,

Since yesterday Firefox has been crashing within several minutes of opening the app. It initially appears to load fine, then begins to stutter and lag around 30 seconds in. At this point scrolling usually begins to stop and the Android UI locks up (can't go to home screen, etc). In addition the bottom Android bar usually flickers on and off.

The crash occurs whether a page is loading or not. It also doesn't matter which screen I'm on (the crash still happens if stay on the new tab page, load a new page, open the settings and hold there, etc). It also occurs when Twitter loads Firefox as its browser.

In most cases the app crashes with no crash log saved to about:crashes. However, around 1 in 10 attempts a crash log is generated. Here are crash stats from the two crashes that made it to

• First Report: android.content.res.Resources$NotFoundException
• Native crash - unhandleable OOM

Actions I have taken to try and fix the issue:

• Check for Firefox and Android updates (both versions were current)
• Clear app cache through Android system settings
• Restart phone
• Disable all extensions
• Close all tabs

I'm not certain this is the correct forum for this report. If posting here was in error please direct me to the correct bug reporting platform.

Thanks

Have be3n hav8ng this problem for at least a week, on a Samsung Galaxy Tab A 8 with Android 14 (One UI). About 20cto 30 seconds after launch, the browser abruptly closes back to the home screen. Have tried resetting the tablet, clearing some old apps out, etc., but thr problem persists.

I have dumped the latest Mozilla Crash Report from my browser. Apparently, there is an issue with memory:

cf13ba46-8115-4130-8396-249e2c218304 java.lang.OutOfMemoryError: Failed to allocate a 134217744 byte allocation with 50331648 free bytes and 116MB until OOM, target footprint 129110320, growth limit 201326592

Can SOMEONE help me figure this out, what should I do, etc.? I am going crazy fighting this..

Whenever I upload a file via my phone (Samsung Galaxy A55 5G), Firefox shows the upload prompt (selecting where the file is going to be) then crashes on its own.

I noticed this when I was using Canva, then tried a few more sites and the upload-crash problem persists all throughout.

Is there any way to troubleshoot this?

Firefox doesn't work on my pixel 7. Firefox should download updates automatically to fix this issue for secure websites. Also, you want us to go through all these steps to fix Firefox? It's not our problem. It's yours. I'm just going to have to delete Firefox. It doesn't work anymore and you don't want to fix it

Hi, I’ve noticed that Firefox on my Android device often crashes or freezes whenever I try to launch or access certain modded APK-based games. I’ve already tried clearing cache and disabling extensions, but the issue still happens.

Is there any known fix or setting that could help Firefox handle these links or game launches more smoothly?

Thanks in advance!

Firefox updated on my Samsung Galaxy A11 this morning and now it crashes every time I try to open a web page. I have tried deleting/clearing the cache, but this didn't make any difference. It sends a crash report. Latest Sirocco link is crash-stats.mozilla.org/report/index/c23c689c-0beb-4a82-873e-0fd850251120

The latest crash:

Hello My Tabs are automatically crash after sometime i open it, all tabs are crasg out and i reload it again and again this is very annoyed, what can i do to stop reloading or crash

I’ve observed a consistent issue across several Android devices using Firefox (latest stable version). When trying to launch or interact with certain modded APK-based games—especially those with unpacked resources or modified DEX structures—Firefox either freezes or crashes unexpectedly.

Interestingly, this behavior doesn’t occur on other browsers like Chrome or Samsung Internet. In fact, some third-party websites seem to handle these APKs with stable performance, suggesting it's not an issue with the APKs themselves but possibly how Firefox handles local server callbacks, file-based intents, or memory allocation under WebView.

I’m wondering if this could be tied to Firefox’s stricter security sandboxing, CSP enforcement, or service worker management?

Are there any logs, flags, or debugging routes I can use to isolate the problem further?

142.0.1 (Build #2016110943), 179e4da8d58fdece16dcbf164c80199917a5946e GV: 142.0.1-20250827004350 AS: 142.0.1 OS: Android 15

Crashes contantly, all the time, after several minutes use it will suddenly disappear and lose everything, tabs, etc., but crash reports are never produced. When it happens the app seems to collapse into the right lower corner of the screen, like a balloon deflating. The Firefox has been uninstalled and reinstalled several times without effect. Why, and what to do about it ?

Firefox keeps crashing and loosing what I type on pages like this.

It happenst the most if you have to check another application or answer a call. But, it also does this when copying over passcodes from other applications to a webpage.

This frequently happens with the latest version on the Android mobile platform.

I didn't change any setting personally anf this has never had any issues until now.

Fix my Firefox so it does not crash when I try to use it. It occurred when I tried to use email and Duck Duck Go. I have not been able to accomplish anything except this complaint since the Upgrade this morning.

Firefox won't stop. No function. Same time: Firefox won't start. Large # of tabs crashed? Hacking? No clue. New version ? 141.0.1, still crashed.

On Firefox Focus, nearly impossible 2 give info here.

ALL my online stuff is on Firefox! No backup 4 long time.

HELP! ◇◇◇ Vani
