I-Firefox ye-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 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?

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

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?

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

Lately my Firefox app window will just randomly close while I'm using it. I notice most often on Facebook, but that's because it's the most often used page.

When I reopen the app, it's like I just opened it, not like it got minimized.

What's wrong with it? I have it updated to current version, as well as I've run malware and virus scans to see if it's my phone. Nothing found.

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.

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.

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

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 ?

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?.

Which, you know, kinda makes a web browser pretty unusable. And I don't want to lose all my tabs, as I have probably hundreds. None of the topic choices really fit.
