Re: And another classic!
Eh? What weird Linux distro are you running where Firefox doesn't only get updated when a new version arrives in the repo, and your package updater does its stuff (manually or automatically, depending on preference)?
Self-updating apps are the sort of crap that only OSes which don't have proper repos (eg, Windows, MacOS) have to introduce as nasty kludges.
