In short, I am looking for the '''Firefox 68 armhf deb'''? '''package''' installation file for '''Raspberry Pi''' OS ('''Raspbian''') '''10'''. --- I use Raspbian 10 (Raspberry Pi OS). I used to keep a Firefox ESR 68 on hold ('''apt-mark hold''') on 1 of my 2 Raspberry Pi machines. I offered this machine to a friend. Now on my only left Raspberry Pi, Firefox ESR 68 is no longer provided by '''apt'''. But I still need Firefox 68 on it, in order to remotely debug my userscripts on Firefox for Android 68.11.0 (latest version to support add-ons like Violentmonkey, thus userscripts) through '''adb'''. Anyone knows how to install it back? I think I need an '''armhf.deb''' file, right? I found: http://legacy.raspbian.org/raspbian/pool/main/f/firefox-esr/ https://archive.raspbian.org/raspbian/pool/main/f/firefox-esr/ https://github.com/jdonald/firefox-armhf/releases But no trace of a version 68 deb file. I then found some '''firefox-68.11.0esr.tar.bz2''' in https://archive.mozilla.org/pub/firefox/releases/68.11.0esr/linux-x86_64/ Is '''x86_64''' same as '''armhf'''? How do we install '''.tar.bz2''' files in Linux? I also see a '''firefox-68.11.0esr.snap''' in https://archive.mozilla.org/pub/firefox/releases/68.11.0esr/snap/ I would like to avoid installing '''snap''' but maybe I should try this instead, does it include '''armhf'''?
