That's pretty harsh. Firefox has always been for me the most awesome browser available.
It's true that Chrome delivered some niceties for user experience and performance, forcing Firefox to follow suit in some areas.
However, Chrome stands on the shoulders of giants, like Firefox and it wouldn't be a good browser without such shoulders. Google should be really thankful to Firefox and I'm sure they are.
Also, Firefox is improving by leaps and bounds lately and after several months of Chrome, I realized that I cannot live without Firefox.
(yes, I'm typing this from Firefox)
