They are rewriting Firefox out of any relevance. They had a distinct product with unique features. It has been loosing uniqueness, usability and mindshare ever since they began shadowing everything the Google guys did. Now they're going all in, turning the thing into a functional Chrome clone. Once the user base drops below a certain percentage, there will be no point for anyone in sponsoring the show any longer.

Me, I was a loyal user since the Phoenix days. I have recently Firefox. It is not unusable yet, but it will be in about half a year.
