I don't understand why Firefox doesn't include an option to download the .deb package instead of tar file for Ubuntu and Debian during release announcements. The market share is already shrinking and why make it harder for people to install or upgrade Firefox? Chrome does it. Why can't Firefox do that as well?
Out of curiosity, don't most systems that use .deb files already have Firefox in the package manager? I was under the impression that Debian now has mainline Firefox (instead of Iceweasel) as of a few years ago
Getting the version from the vendor can be more ideal, since there’s no dependency on one party to keep another party’s software up to date, especially where distribution versions are concerned.
