Along with the release of Safari 5 can now set the extension. These additions are written in javascript using HTML5 and of CSS3, can extend the functionality of the browser. Summer on Apple.com promise to add a special section with the best extensions, and while they can be downloaded from the developer's website. A good source of information about new addons began to blog safariextensions.tumblr.com.
I looked a little longer extensions, but after the test were only SafariRestore (Automatically restores the tabs that were opened in the previous session) Invisible Status Bar (Very good addition which hides line status by displaying it only when the cursor is on the link) and Google Reader Styles (Set for Helvetireader style).
Tell us what extensions you use? And what in any case do not recommend because of their glyuchnosti? Following the results of the survey will review the post, which will help other readers to choose the most useful extensions :) Your opinion is very important.
