I use this on my FreeBSD workstation. I would prefer Chrome (which is what I use on my MBP) but Chrome on FreeBSD is not quite there.
I use FF on desktop, but Opera on my Ideapad S10 netbook (on ubuntu). Opera is definitely faster on limited resources than FF and way more complete solution than FF (turbo mode, opera sync, etc)
And Android's built-in WebKit-based browser.
FFox here, but the read-only browser is Konqueror without Javascript. Two browsers are better than one ;-)
