not entirely true. firefox has solved a lot of startup and other performance issues, but the core rendering engine still lags when confronted with heavy loads, just a scrollable div of a couple dozen large images is enough to make it stutter seconds at time while they load and render, sure it's partly a developer issue for not using thumbnail in the listing, but chrome shows them all with zero lag.

stating that the only reason chrome is ahead is because advertising is disingenuous: firefox only started catching up with them only in the last three-four years performance wise and the gap it's still there.
