That's relatively irrelevant - Chrome was much faster at the most important sites - which are coincidentally mostly google owned - but still faster - GMail, Youtube, Google itself felt faster on Chrome back then. Then there's the flash handling which was important back then. Also FF was shitty at stability, it didn't have multi process architecture for the longest time and I've had a page crash my entire browser (especially in the flash days) regularly. And then chrome started pushing excellent dev tools (even in FF nightly I get dev tools hanging on complex sites because of how slow they are) Chrome was the better browser back then and it won the power users and developers, then it took over the casuals as it was advertised on google and it was recommended as the best by everyone - it took FF too long to catch up and now a lot of sites don't even test compatibility - I've been trying to switch back to FF before this fiasco for a month and it wasn't a smooth experience compatibility wise.
