Yeah, if only their dev made a fix to allow sideloading in mobile firefox (asked about it on the github and he refused). That's one of the things I'd hope LibreWolf on android could do, just let me install a damn xpi file from internal storage already, I don't want to be forced to use AMO and their stupid extension lists thing, just want to install any extension I choose, bugs be dammed, whether Mozilla approves it or not.
