From the ‘I Did Not Know That‘ files:
Firefox 4 is nearly done and one of the first things that most users are likely to notice occurs right at the start-up.
Firefox 4 starts faster than any previous version of Firefox.
I recently visited Mozilla’s Toronto office and got some really great insight into how Mozilla was able to speed up the Firefox start-up.
“You know how every day Firefox pings to get a list of blocked add-ons for security, what we send in that ping now is one number and that number is, how long did it take you to start-up this morning,” Mike Beltzner Director of Firefox told me. “So we’re getting live start-up data from the field.”
