I installed several of them in one gulp, including AdBlock-a great though dubiously ethical way to keep lots of tabs open without slowing down your computer. It’s already got a huge library of Firefox-style add-ons that improve many different parts of the browser. (For instance, here’s a script that turns all Google pages black, purportedly to reduce “eye fatigue.” Here’s another that lets you accept all your Facebook requests at once.) Finally, and most importantly, Chrome now does extensions. The browser now also runs Greasemonkey scripts, little bits of code that allow you to change how certain Web pages are displayed.

Bookmark syncing is now built in: Turn it on and your bookmarks are available on other computers running Chrome.

Late last month, Google released Chrome 4, the latest “stable” version of the browser. With Chrome’s latest upgrades, all that has changed. Until Chrome added these features, I couldn’t leave. There were many Firefox extensions that I couldn’t do without, including ones that blocked ads and kept my bookmarks synchronized across computers.

Firefox’s main virtue is its flexibility-it’s got a huge gallery of add-ons that give it many fantastic powers. But Chrome originally had a few shortcomings that kept me from signing up full-time.
