Hello Mike,
you're rather rudely asking the maintainer to spend time on things you'd like to
see done, which is not how volunteering in Debian works.
Luckily, you don't have to be the maintainer to do the job you're asking for.
You yourself can triage every open bug and then decide if it is fixed in current
versions of firefox. For that, see https://www.debian.org/Bugs/server-control,
or check out the `bts` man page that comes with installing the devscripts
package on how to change bug states.
Be the change you want to see in the world!
Regards,
Lee (not the firefox maintainer)
