Firefox for Android Community Forum

Mozilla has announced that:

> Beginning with Firefox 144, the minimum supported Android version will increase to 8.0 (Oreo)

Where can we download version 143 to install on older devices (Android 5 to 7) from now on?

Hi, looking to ask if anyone has experience with restoring Firefox open tabs after closing them accidentally on Android.

Environment: Android 14 Firefox account sync enabled

Things tried: 1. Firefox Sync (The open tab information was promptly cleared away by the sync) 2. Open tab information from a separate desktop Firefox browser with Sync enabled prior (same issue as #1) 3. ADB file access (no permissions) 4. ADB downgrade install to pull old files (failed due to Android 14) 5. Accessing "files:///data/data/org.mozilla.firefox/..." (cannot download files and looking at the timestamps, the SQLite files have probably been overwritten) 6. Firefox debugging (Nothing useful) 7. Searching for a way to get Firefox Sync historical data (doesn't seem available) 8. Mailing customer support (No response)

Things I didn't do prior to this incident (answering the common responses found online): 1. Bookmark my tabs 2. Firefox Collections

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'm trying to delete the recent history links that come up after going to a site and they won't delete. Swipe was better to see site links I don't delete and now it's a show all that doesn't let you delete.

I have been using Firefox on both Windows and Android phones. I recently lost an S-23 to a virus. When I was setting up Firefox on the new phone I got a message that Firefox had detected the Vezeen virus on the old phone and the new phone. I immediately cleared the history and cache but the message still remained so I uninstalled Firefox.

 Vezeen is identified as a phishing virus and the effect on the old phone was that it switched from site to site so fast it was almost impossible to put commands into the phone. I traded the old phone in so it is impossible to know if it has been thoroughly scrubbed.
  Thus far I have seen no effect on the new phone or Windows device.
  Suggestions?  Open a new account or what?  I have tried swearing with no success. I am going to leave Firefox off Android devices until I have more confidence.

Firefox still eating too much RAM when to many tabs are open, optimisation would always be welcome naturally.

But maybe also looking into something like a system, that puts certain tabs that haven't been used for a long time into something like a sleep mode?

When I connect my Bluetooth earbuds to watch a video on Firefox browser it works fine. But when I disconnect my Bluetooth ear buds the video stops playing and cannot be played through the phone anymore.

I refresh the page, choose another video, close the tab, open a new tab and now the video does not even play at all.

When scanning the QR code, my phone is stuck on this: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-10-12-17-54-22-6b261a.png While my desktop shows this: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-10-12-17-55-00-1c9ca2.png

When signing in with email on my phone, I get an "Unexpected error": https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-10-12-17-56-18-5c7b93.png

I've tried everything. I've cleared the app's storage and also re-installing the app. I've removed the old device login from "Connected Services" in https://accounts.firefox.com/settings.
