Mozilla distributes ready-to-use Firefox binaries for Linux on their website: On DebianUnstable, to install the Release version of Firefox, install the firefox package. Support for languages other than English is available in packages named firefox-esr-l10n*.

They are instead supported for more than a year, updating with major security or stability fixes. ESRs are not updated with new features every six weeks. This installs the Extended Support Release of Firefox. On DebianStable, Install the firefox-esr package. Migrating from Debian's Firefox to Upstream's.
