> Realistically another browser engine really isn't needed. 2 is enough. Currently the internet is what Chrome is - if Google decides that they don't like something on the internet, they can just wipe it. Firefox is dying. (And Safari is... well... it does things). The internet has been rotting away for good part of the last decade. We definitely don't have enough browser engines, we are in dire need of more.
> Firefox is dying Then I don’t understand how this new thing will not be stillborn. It is years before becoming usable and even then it will be worse than Firefox.
Firefox isn't dying because it's a bad browser or because it has no place on the market. It is dying because of mismanagement, mostly for not knowing what their users really want and need. They have no idea why their current users are using their browser, instead of Chrome. They just go with the stream, and seemingly are content that Google is keeping them on life support.
But it doesn't mean that new browsers will make the same mistakes, or that there is no need for new ones at all.
With that said, I would be lying if I would say that you are completely wrong. I just don't want you to be right, regardless how slim of a chance it is, because the state of internet is not getting any better that way.
