That’s hard to prove or disprove without having an alternate universe ready for A/B testing.

Although, frankly, I can’t shake the feeling I’ve been living in the B-branch for, say, the last two years. If so, let me just say: if your results are not yet conclusive, please ask your statisticians for what “multi-armed bandit” means to them, then shoot them if the quizzically look at you. You may even skip the question.

Back on point: I know many people who use Firefox for “ideological” reasons. In fact, anybody who still used FF as of 6 months ago arguably fell in that group, save some extreme cases of inertia.

But, even more tittilating: Firefox seems to be once again be competitive wrt performance. That may just be its salvation, and not a moment too early to make it dramatic.
