Bug#843219: reglookup-doc: Please don't depend on firefox-esr

[Jeremy Bicha]

Package: reglookup-doc
Version: 1.0.1+svn287-4

Please don't have reglookup-doc depend on firefox-esr.

There are many -doc packages in Debian that provide HTML documentation
and as far as I can see, reglookup-doc is the only one that depends on
firefox-esr.

Some users may prefer a different web browser and some systems (like
Ubuntu) don't have firefox-esr available.

I recommend not depending or recommending on any browser since
documentation packages may be installed on desktop or headless servers
and the best browser differs significantly for those cases.

Thanks,
Jeremy Bicha
