Other than Abrowser or Midori: Netsurf, Epiphany (labeled 'Web', package
epiphany-browser), Qupzilla, Konqueror, Icecat. Trisquel only includes
free/libre software in its repositories.
There must be a reason why Seamonkey is not included, but it can be
downloaded easily and run from its
Trisquel mini includes midori, but I strongly doesn't recommend to use it.
Abrowser is the best choice in my opinion. If you are paranoid then use
IceCat.
Thanks.
Is there a secondary web browser choice included too, or is Abrowser the only
one?
Abrowser is the default browser. It's a rebranded Firefox with better privacy
settings, albeit not as restricting as Icecat would be. Ruben calls its
settings "sane".
