Firefox til Android Community Forum

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..

Currently using android 15, can i hide hide this in firefox's setting? If not, please mozilla, add an option to hide the background behind the bar, it's sucks. I did research and found that it is an app issue and not an OS issue, thanks

Hello Firefox Support Team,

Thank you for providing such an excellent browser, free of charge and without advertisements.

I am experiencing an issue on my Samsung J5 running Android 5. When I try to set Firefox as the default browser, I am redirected to an information page. While helpful, it does not mention that Firefox cannot be set as the default browser on Android versions below 8.

It would be clearer if this limitation were explicitly stated on that page.

Thank you for your attention, and best regards to the entire Firefox team.

When I click on YouTube comments to read them Firefox mobile pops up a blank window. Works fine if I switch to desktop mode. Android Version 16. Tried reinstalling Firefox. Cleared cache and cookies. Nothing so far has worked.

Would it be possible in your next release/update to allow us to put our collections into alphabetical order for ease of finding if you have a lot. Thanks in advance. Chris

I AM JUST TRYING TO MAKE SURE THAT MY MOZILLA FIREFOX ANDROID BROWSER SETTINGS MATCH MY VPN BUT SOMEHOW I CANT GET TO THE ABOUT:CONFIG PROBABLY BECAUSE I AM USING AN ANDROID BUT THERES GOT TO BE A WAY T OK MAKE SURE MY VPN AND MOZILLA ARE ON THE SAME PAGE. I HAVE BEEN GOING IN CIRCLES ALL NIGHT SOMEBODY PLEASE HELP ME.

I have tried logging out and logging back in on my android firefox. accounts.firefox.com shows it is logged in, yet I do not see my firefox on android listed in my "Tabs from other devices"/"Synced tabs", in fact, I do not see any other device tabs listed. On my android firefox, it shows that I am logged in, yet the checkmarks for choosing what I want to sync are all disabled, the sync now button can be clicked but does nothing. I have tried logging out, forced stopping firefox app, and restarting android, nothing worked.

I get this message when I email to people on Yahoo, comast.net and others. MAILER-DAEMON <postmaster@earthlink-vadesecure.net> yesterday

Hello, I have a reproducible issue on Firefox Beta for Android on my POCO X6 Pro 5G running HyperOS / Android 15.

When tapping mailto: or tel: links in Firefox, nothing happens. No app opens and no chooser dialog is shown.

The same links work correctly in Google Chrome, so the Phone/Dialer and Email apps are properly registered with the system.

This appears to be related to Bug 1988946, but it also affects Android 15 on HyperOS.

---

Steps to reproduce

1. Open Firefox Beta on a POCO/Xiaomi device running HyperOS.

2. Visit any webpage containing a tel: or mailto: link.

3. Tap the link.

---

Actual Result

No action is triggered.

No Intent Resolver popup appears.

No dialer or email app is launched.

---

Expected Result

tel: links should open the default Phone app.

mailto: links should open the user’s email app.

If multiple apps are available, Android should show a chooser dialog.

Device Information

Device: POCO X6 Pro 5G

OS: HyperOS, Android 15

Firefox version: Firefox Beta 146.0b4

Build: #2016126791

GV: 146.0-20251117130030

AS: 146.0.1

Build date: 2025-11-17T13:00:30

What I have already tried

Enabled “Open links in apps” in Firefox

Reset Firefox default preferences

Reset Phone (Dialer) defaults

Granted all special permissions (background activity, pop-ups, etc.)

Tested Firefox Stable and Beta

Cleared app cache/data

Rebooted device

Verified that Chrome opens tel: and mailto: links correctly on the same device

---

Additional notes

In HyperOS settings (“Opening links”), Firefox does not receive supported link types.

The Phone app does not appear in “Opening links”, but it works fine with Chrome.

This suggests a compatibility issue between Firefox’s intent handling and Xiaomi/POCO HyperOS on Android 15.

---

Conclusion

This issue is reproducible 100% of the time and affects basic link handling functionality. I am available to provide logs or run additional tests if needed.

Thank you!

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

No doubt this has been asked before but I haven't found an answer, apologies! Just got a new phone. I have well over 100 tabs open on Firefox on my old phone and want to move them over to the new one if that's possible. The phones are synced but alas that doesn't do it. Is there a way to transfer all those tabs over to the new phone without copying every single Web address the hard way?
