I found three, Betterfox, arkenfox, & Narsil.
I been using Betterfox for the last week. I been liking it because Betterfox doesn't break sites. Back in the day, I tried arkenfox. But it break some sites I go to. Narsil is a fork of arkenfox.
none.
I try to live by the rule "if it isn't broken, don't fix it", and I haven't observed anything broken so far, so no need for tweaking stuff.
