Firefox for Android 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.

Firefox mobile browser app (Samsung Galaxy S21 Ultra, OneUI 7, Android 15) crashes after a few minutes even though account was logged out, and cache and mobile data cleared before app was uninstalled, and reinstalled with re-logged account.

This is my default mobile browser since I had my mobile phone. The app started crashing the first time that I logged out my firefox account, and the problem remains.

Dear Sir/Madam, I have Firefox as my main browser on my Samsung Galaxy S21 phone and recently it keeps crashing. Constantly I am using this medium to ascertain whether you are aware of this extremely annoying issue and if so how do you suggest that I should proceed in order to correct same. Best regards, Volney Boswell

After updating to 150 (any subversion), FF crashes on almost start - I can load a page but loading another page or a video in the page will stop loading after a while and crash within 5-10sec. No about:crashes generated. No crash if I only browse the page that's opened (except if I load extra content like videos). FF remembers if I navigate to another page before the crash, it'll open the navigated-to tab (provided it has been long enough, small pages load, big pages don't). It really looks like after loading a fixed amount of data it just stops loading and crashes, taking the full browser down with it. Note that there is likely 500+ tabs opened (even though it's never been a problem), cache was cleared and extensions deactivated.

For the first time in many many years, the beta's unstable (brillant track record for a beta)!

Hi.

I have recently set firefox as my default browser on my Google pixel 8a.

I have had to clear all data from my Firefox browser twice in 2 days. First time I didn't know what was going on and saw in a search that when your browser stops loading try clearing all data, and it worked.

Second time was when opening a link from a Google pixel email about new features: Google pixel new feature link .

When it happens no page will load, the tab just remains as a black screen. This happens to all tabs that were previously opened as well as the new tab from the link.

I don't know if this is because of links from Google mailshots, or links opened from Gmail (don't think so), or what, but having to clear all data daily is a big issue. History, logins, cache, etc, lost.

It definitely need a fix please.

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.

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.

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.

The latest crash:

HELP!!!!

Hello,

I've noticed that recently that Firefox seems to repeatedly crash on my Xiaomi phone quite frequently. It's a Xiaomi 15 Pro on HyperOS 3.0.7.0, and here are some of the crash reports:

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?.

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)

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?

Browser crashes frequently browsing randomly with crashes in about:crashes similar to

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

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.

I was attempting to use the Pinetools.com photo editing site on Firefox for Android, and it sent Firefox into a crash loop - I had to uninstall and reinstall. I was able to replicate this one more time. Here's exactly how it went down:

• went to https://pinetools.com/add-noise-image
• uploaded and filtered the photo
• "right"/long-clicked it to open the edit in a new tab, which immediately sent Firefox into a crash loop
• uninstalled and reinstalled Firefox when it became clear that closing the app wasn't solving the problem
• replicated the above steps, to the same result
• uninstalled and reinstalled Firefox again.

I have uBlock Origin and Privacy Badger, and reinstalled them both times - is there any chance I could have put my device/info at risk?

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?
