PC-BSD does not really have an "included" web browser. Each of the available desktop environments could or could not have an included web browser (for instance: KDE uses Konqueror, Gnome uses Epiphany, etc...). The PC-BSD Team does not make a "favorite" choice for the OS, we just make as many PBI's available so that the user can choose what fits his/her needs.
These web browser PBI's are generally available under the "Web" category and include: Firefox, Chromium, Opera, Epiphany, Dillow, Arora, Midori, Lynx, NetSurf, rekonq, SeaMonkey, XXXTerm, and probably a couple others I missed....
You can just read through the descriptions of them and choose any/all that you wish to install and try them out. Because of the way PBI's work you can always just remove any program that you do not like at a later without any downsides at all.
