Firefox til Android Community Forum

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

OS: HyperOS, Android 15

Firefox version: Firefox Beta 146.0b4

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?

Hello,

I am currently on the latest version of Firefox Beta for Android, version 146.0b4.

For some time now (6+ months), this installation of beta fails to sync my bookmarks from or to Mozilla's servers. I've verified that desktop Firefox and Firefox stable on Android will still sync.

It took me some time to notice this was the case, and at first I hoped it would resolve itself, but it hasn't. I have many newer bookmarks on this installation of the browser, and if I reinstalled in an attempt to fix this issue, I would lose these bookmarks.

How can I keep my newer bookmarks on mobile, while also fixing the sync functionality? There doesn't seem to be a way to backup bookmarks on Android other than sync, which isn't working.

Other sync data aside from bookmarks is still syncing fine. I tried signing out of Firefox on all devices, then signing back in, but that didn't resolve the issue.
