And that is truly disturbing, because it is not an implausible future where even Mozilla is finally compelled to rebase Firefox upon yet another Chromium fork, just to stay relevant with the fast-moving, extremely complex web ecosystem. Of course if their market share improves then they'll still be able to exercise relatively significant influence upon the Web's direction, but the big challenge in front of them is expanding their user base. They're in a kind of catch-22 situation I feel... it is going to be difficult to reclaim the slipping ground.
