How do I go about installing Firefox 80.3 (which is the latest version) for Slackware 14.2?

use ruario's firefox script. It will download the latest firefox and repackage it into a slackware binary

Yes but note that ruario's script is still broken with respect to Firefox upgrades. Whenever you install an upgrade using that, Firefox will start you in a new, blank profile.

other options could be:

- all-in-one .tar release by mozilla, which works on pretty much all modern linux distros, just extract, symlink somewhere comfortable and run.
this will also handle automatically updates if you give the correct user permissions to the extracted folder.

- flatpak release, i've not tested this but i heard good things. You will need the flatpak package (and its dependencies) from Slackbuild.org

You can take the desired version here :

Yes, for now I would advise using @drgibbon's patched version of ruario's script:

wget https://gist.githubusercontent.com/d...est-firefox.sh

I just dragged Firefox desktop entry to my desktop and made this simple mod to it.

Also I took the default profile and renamed it so I can always identify it (used my initials). Not broken for me now. I use this icon to start Firefox and it always works the way I want

Also possible, but breaks if you start Firefox as a direct command (say from the console or something). Anyway, I'd like to see ruario fix it, I think it's safest to just install/upgrade according to what Firefox expects, but it's been over a month so who knows.

DDG "firefox profiles". I didn't think up this by myself. Mozilla changed how Firefox does business along about version 68.0. I just made it palatable for me.

EDIT - I was wrong. Firefox 67.0 was the first version to cause grief with this new (ugh) "feature".

Yeah, I understand how profiles work. The bug in ruario's script is that it installs Firefox to a new directory (namely, "/usr/lib$LIBDIRSUFFIX/firefox-$VERSION") when it should be installing to a consistent location (either "/usr/lib$LIBDIRSUFFIX/firefox" or maybe "/usr/lib$LIBDIRSUFFIX/firefox-$FFCHANNEL").

When the location on the hard drive changes (which happens on every upgrade if the directory has $VERSION in it), Firefox creates a new profile. That doesn't happen if you keep the install location the same. So it's not a Firefox problem at all, it's the way it's being installed.
