"Performance is a huge, huge, huge thing for us," said Mike Beltzner, vice president of engineering for Firefox, in a Webcast on Tuesday. "We created the performance story, and we've got to keep at it."
Mozilla will also work at improving the perception of speed, which is just like it sounds. Changing the order that elements appear on a page doesn't necessarily make the page load faster, but it can appear that way.
"We are in it to win it," Beltzner said. "It's no longer the case where it's all easy wins. There's hard work to be done here. We have to make sure we're the ones leading the charge in keeping the Web open for users."
