Firefox

Good luck with even maintaining that fork up to date , with security threats and web standards changing so quickly.

The thing is, people willing to maintain a fork could contribute to Firefox today, and reduce the development cost, reduce the need for income.

Sure, some people will be more willing to contribute, if it's a pure grassroots effort, or if they're left without a browser otherwise, but to just assume that a fork will fix it, that's wishful thinking.

I wish that most forks wouldn't be even worse. Pale Moon, the most interesting one, is a gang of patent trolls.
