Not work with Fennec 62.0.2 @ android 8

While PassIFox does not work with latest Firefox, this works great.

Works well with KeeWeb in FF and it is good alternative for internal FF keystore crash (covered by automatic backup for keepass database).

I am not able to connect my database, when I click connect nothing happens

I love this addon, however, why was the username shortcut changed?
I would definitely prefer Ctrl+shift+u
