When the search outfit Google released its Chrome browser for the Mac it was was with the ability to use extensions disabled.

Mac fanboys had to wait nearly a year to try Chrome on their fruit flavoured toys and when it arrived it was effectively knobbled. Now extension support is active again and bookmark synchronisation has arrived in the Google Chrome developer's build for Mac OS X.

Bookmark sync does not yet work as a bug related to the sync process will crash the browser when you add a new bookmark folder. But at least you can get some of it to work. The recent developer's build, version 4.0.288.1 which is available for Windows, Mac, and Linux shows how far behind Google is with the Mac versions. Windows users will only see two bug fixes: one prevented HTML5 audio and video content from not loading, the other stops content scripts from running twice on some occasions.

But the Mac and Linux versions actually get new features which have been on the Windows version for a while. Google added for Macs "pin tab" as a context menu item and included a "learn more" link on the crash page. There is also an Esc key as a shortcut to stop the page from loading.
