===== Installing Fennosys root CA to Firefox (Android) =====

We begin by downloading Fennosys ROOT CA:

  * https://manuals.c1.fi/certs/Fennosys-PN-CA.crt

Do not attempt to install it from Firefox (It'll refuse to do it). Instead we now go to..

 * Android Settings -> Security & Lock Screen -> Encryption & credentials -> Install a certificate

{{:en:support:fennosys_root_ca:ff_android:screenshot_20211003-094518.jpg?300|}}

Select "CA Certificate" 

{{:en:support:fennosys_root_ca:ff_android:screenshot_20211003-094548.jpg?300|}}

Select "Install anyway". The device will now ask your PIN. Enter the PIN and continue.

Tap on "Fennosys-PN-CA.crt"

{{:en:support:fennosys_root_ca:ff_android:screenshot_20211003-094622.jpg?300|}}

So our CA is now installed to Android's CA store! =)

Next we'll setup Firefox to use Android CA store so that it'll work with the CA we just added.

  * Open Firefox -> Settings -> About Firefox
  * Click Firefox logo 5 times (There will be small pop-up saying "Debug menu is enabled")
  * Back to Settings
  * Secret Settings -> Activate "Use third party CA certificates"

All done! =)
