Firefox for Android Support Forum

Two Oct 2017 microprocessor chipset vulnerabilities have been used on phones manufactured through July 2019, that allow Foreign Bad Actor APT groups to develop cofe, based on reverse engineered Open Source code, to download multiple apps, including browsets, GBoard and other alternative keyboards, and communications apps (Gmail, text and messaging, phone ) applications.

These copy apps run in the OS at startup (using a thumbnail hackede Opera version - but not the expected Opera Mini version for Android), and are oberved as duplicates when clearing app cache, as repeating application responses to a command. They also appear as phantom duplicate app notifications, in Rent Apps List toggles, and hidden apps in hacked desktop Launchers)

The malware payload launcher may also be appended to poorly written apps, from third party app stores, but also from malware originating from Chinese made inexpensive phones with continued 2017 chipset vulnerabilities, eg older chipsets not soft patched or replaced eith hardcoded newer code.

Therefore, we suspect tens of millions of compromised phones are in use. These phones leak small communication pack streams of scavenged user information while the phone is on, regardless of hacked Launcher UI status indicator (off) and through hacked BlueTooth and Nearby Share applications using javascript and Lineux remote toggles, that can activate and use camera and microphones to record user calls and environment.

Perhaps authenticator checks buried in code, could alert users of duplicated browsers, as all other FF privacy protections are nulled by these hijacks.

Mozila VPN on Android sometimes appear to automatically turn itself off.

The explanation could be in your settings on Android: Go to settings, - select Apps, - - choose Mozilla VPN in the list, - - - go to Battery and select background Use,

go back to Mozilla VPN in the list, - - - go to Mobile Data, - - - - turn On "Allow Background Data Usage" - - - - turn On "Allow App while Data saver is On"

now your VPN shouldn't turn off any longer.

When restarting your phone the explanation why the Mozilla VPN is OFF is that to keep your security, the app requires re-authenticating with their servers (new encryption key).
