Pushing more on the basis it's becoming less popular isn't going to work. People were getting pushed from IE to Firefox and stayed there because IE was an all around pile of stagnant hot dog shit in comparison, not because a few evangelists were worried about percentages.

Unfortunately the differences between Firefox and Chrome are nowhere near as great as the differences between Firefox and IE were. At the same time there isn't another non-Chromium based browser that fits the bill either, especially with MS throwing in the towel and Apple not caring about other OS's.
