Currently, almost the most important element of a web browser (as well as many other types of applications) is ability to adapt it to a specific user.

I think that everyone heard about the extensions for Firefox, but the situation is much worse when we look at Internet Explorer or Opera. Who knows, maybe this is the mystery behind the big popularity of Firefox.

Anyway, Google is always learning from the market leader and this time, simultaneously with releasing Google Chrome Beta, Google opens the extensions place for Chrome and open source Chromium browser.

Now at the project site you can find extensions such as Xmarks or GMail Checker and hundreds more.
