Firefox for Android Community Forum

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.

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:

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

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 version 134 of Firefox Android has been out, it crashes EVERY TIME when I try ot use the "back" gesture on my Xiaomi 14(i.e. swiping from right or left side of the screen) I tried Firefox 134, Iceraven 2.27 (also based on the same Gecko) - they act the same. In the same time I also have Waterfox, based in the previous version of Firefox 133, and it responds properly. I guess it is related to the latest version only. Here's the crash log:

f5e34211-feda-4d80-b244-c2e4db76c44d java.lang.NullPointerException: Attempt to invoke virtual method 'float android.window.BackMotionEvent.getTouchX()' on a null object reference

Hello, My firefox app stoped working today(version for androids). I uninstalled it and installed it twice but it still won't work. When I open it, it stops working after a few seconds and I recive a notification that it crashed. What should I do?

Hello. I recently found an issue with Firefox Nightly for Android crashing upon pressing a volume key.

I haven't fully explored the bug yet, but currently, I have found that on YouTube, it will crash consistently. I can report later if it'll crash on another site.

Any thoughts? I don't get an error message, so I can't narrow it at all.

It is what it sounds like. Just merely switching to it crashes it. Previously I was struck on Private mode but after reinstalling, I'm now struck on normal mode. Don't know if it's a bug or whatever but it is what it is. It noticed this around a week ago but don't know it was there even before that. Last time I left it on Private and didn't switch but when I went to switch Last week, it crashed.

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.

Hi Firefox Support Team,

I am experiencing an issue with Firefox on my Poco X7 Pro (HyperOS). Pages in tabs automatically reload when returning to the app after switching away, even after only ~1 minute. This happens despite all of the following:

- Battery optimization disabled (No restrictions) - Background activity allowed - App Lock enabled in Recent Apps - Tabs → Close inactive tabs = Never - Delete browsing data on quit = Off - Developer options → Background process limit = No limit - RAM Plus active (~12GB available)

In comparison, Chromium-based browsers like Vivaldi maintain tabs for hours on the same device without reload.

• • Device:** Poco X7 Pro
  • OS:** HyperOS (please add exact version / Build number)
  • Firefox version:** (147.0.3, e.g., 125.0.1)
  • RAM:** 12GB RAM plus active

• • Steps to reproduce:**

1. Open Firefox and navigate to any web page. 2. Switch to another app or go to Home. 3. Wait approximately 1 minute. 4. Return to Firefox. 5. Observe that the page reloads and previous state (scroll position, forms, media) is lost.

• • Expected behavior:** Tabs should retain their state unless the system completely kills the Firefox process.

• • Actual behavior:** Pages reload automatically, even when the process is still in memory.

• • Logs / Attachments:**

- adb logcat / bugreport (firefox_reload_log.txt or bugreport.zip) - Optional screen recording demonstrating the issue - Timestamps of occurrence for reference

Could you please advise if there is a recommended configuration for HyperOS/Poco devices, or if a workaround exists to improve tab persistence for Firefox (Gecko engine) under aggressive memory management?

Thank you for your help.

Best regards, AmirAbbas

I need to change some config settings to prevent some problems that corrupt the screen or crash Firefox on android almost every day. I found that using a Bluetooth reduces the frequency of these problems, but it still happens and is very frustrating.
