#overbitenx and #onyx work well on #firefox on #slackware after a bit of fiddling for reading #gopher directly (without proxy).
So do #lynx , #mosaic-ck (!) and, of course the old pre-quantum firefoxes (with the respective overbite ext).
As does #dillo !! - but had to add some extension (dpi) to that - dillo fans know all about it.
