Edge has serious development effort behind it, and isn't just a skin

Edge represents the best possible case for browser forking: a company approximately the same size as Google, with approximately the same technical resources, and a history of in-house browser development to boot. Most forks are a far cry from that.

[jefftk]

Yes, very similar to when Google started using WebKit for Chrome (which eventually ended in a full fork)

[woodruffw]

Right. But I don't see how either of these successes by large, cash-rich companies bode well for a random fork of Firefox.

[jefftk]

No argument there. A full browser fork is a serious investment.
