Author Note

mozjs* contain a copy of the SpiderMonkey JavaScript engine. It
is not feasible to backport security fixes to the mozjs*
packages, as such, marking them as ignored.
starting with Ubuntu 22.04, the firefox package is just a script
that installs the Firefox snap
starting with Ubuntu 24.04, the thunderbird package is just a
script that installs the Thunderbird snap
