I’ve been running the Firefox 4 betas, and I’ve been trying to keep an eye on speed, as that seems to be one of the main reasons cited for switching to Google Chrome by Firefox users I talked to.
Now, don’t get me wrong, Chrome is fast, that much is true, but I think what a lot of people forget about is the cruft. For many users, it could be a few years since they’ve done a fresh install of Firefox. I mean fresh as in “starting with a new profile” so that all your old preferences, add-ons, plug-ins, bookmarks, and other bits weren’t there.
Right now if you download Google Chrome for the first time, and launch it, there is no cruft. It launches fast. If you’ve been upgrading Firefox over the years and not starting fresh with a new profile… well, there’s cruft.
Here’s what I did, and you can try it at home. Create a new user account (if you’re running Mac OS X, just log into the “Guest Account” that wipes itself after every logout) and launch the Firefox 4 beta. For fun launch Google Chome as well. Both will be cruft-free as they won’t have any previous preferences/profile to worry about, and will be starting fresh.
In my tests, Firefox 4 launched pretty damn fast. If Chrome launches faster, it’s probably by such a small amount that most people could never tell.
Now jump back and forth between Firefox and Chrome and load various pages. Again, don’t use any magical timers, just experience it, and see if you think they are pretty close. They look pretty close to me.
As I’ve mentioned, speed isn’t everything, but it’s nice to see the Mozilla folks stepping up their game and realizing that speed is important to a lot of people. I’ve also read some comments about finding ways to “cleanse” old profile data, to help the folks who have been using the same Firefox profile for years and years, hoping for a bit better performance.
