Extensions in Chrome are pretty nifty. They offer a one-click installation method and the browser doesn’t even need to be restarted for the changed to take place (are you taking notes Mozilla?). But this is nothing OS X and Linux users should be jealous of… since they got extensions back in December.

Something they should be jealous about is the bookmark sync feature. This new ability lets Chrome users sync their bookmarks with their Google account and maintain the same bookmarks across different computers. Sounds familiar? delicious.com (formally http://del.icio.us) has offered the same service for a few years now – but with the inconvenience of having to log into a web-based service to add and access your favorites. Google has simplified that by auto-magically syncing the bookmarks to your Google Docs account.

At the moment, the only one-up that poor Delicious.com still has is that you can share these links with others. While theoretically you could simply share the “Google Chrome” folder that gets created in your Google Docs file… Google has disabled the ’share folder’ feature for it. But it’s only a matter of time before Google deems Delicious.com as useless and no longer necessary.
