Is it just me or are Chrome's dev tools superior in every way to FF?
Going back on topic, I've stuck with Firefox for years because of DownThemAll and Firefox Sync. But I stopped using sync a couple of years ago, so that just left DownThemAll... which won't work after this change. So I'll probably leave Firefox behind. Safari supopsedly gives you better battery life on OS X, and Chrome is more popular (i.e., people probably test their stuff on it).
