Firefox for Android Community Forum

I'm getting a lot of crashes lately. I've restarted my phone, force closed Firefox and deleted the cache. Didn't fix it unfortunately. Firefox Android Mobile 134.0.2 (Build #2016068999)

Here is the error: 95dfeae4-16a9-45bd-8474-02ede37eb9dc java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

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.

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?

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!

I already reported this and still nothing changed

can't flip the camera bottom left. and it keeps crashing while talking to people

downloaded user agent switcher EXTENSION. switched to ios ipad (because that's the only way you can use ome tv on a android browser). go to ome tv site . logged in.

Actual results:

the camera flip option in the bottom left not working!! it just shows my rear camera

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 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

Since I upgraded to the latest version, Firefox is sluggish and crashes on a regular basis. I have changed my privacy settings from strict to default, has not changed the problem. How can I go back to old version? I choose Firefox because of the privacy concerns, and understand that some websites won't work well, but I've never experienced consistent problems with the app crashing.

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.

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?

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.

HELP!!!!

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 ?

Hi, the latest nightly version crashes everytime on my Pixel 8 Pro. Clearing cache, force stopping and restarting the phone doesn't help.

version 141.0a1 org.mozilla.fenix

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.

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

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

Recently, I've had an issue with your browser on my desktop. I use AOL for my homepage. When I open the browser, it takes a long time to load. When it finally does, sometimes the tab crashes immediately. If it doesn't, I try to open another tab and that will crash. I don't have the problem when I use Edge. Any suggestions? If I remove Firefox and reinstall it, will I get all my favorites back?.
