Installing Waterfox G3.2.5 (2021)

I'm running Kubuntu 20.1 and have downloaded the tar.bz2 file to install Waterfox (browser) however there seems to be no means to complete an install or at least I'm too rusty to figure it out

I've tried the traditional make and make install functions to no avail
I can only launch the binary via ./waterfox while in the extracted folder

am I missing something? None of the available package managers seem to offer the latest G3.2.5 version and I do not want to run Classic
