I've always used Firefox (at least since i switched from IE6 LOL)

but my most important features can be summarized (mostly) here: https://wiki.mozilla.org/Security/Tor_Uplift/Tracking

86 little bugs... but this as a personal user.

As a business user there are others that need to be fixed (pwa features, i'm looking at you!!!).

but then again... I've already made the switch, so...
