My first post....
I want to write an extension that deletes duplicate bookmarks (Bookmark sentry is great but limited to 100 bookmark deletions, I need unlimited).

Is plug in = extension?

Where can I start learning?

Thanks much!!!

Ok, you'll find the official documentation here: http://code.google.com/chrome/extens...etstarted.html including a basic tutorial and a complete reference.

On top of that you'll find a lot more examples on google ... but for me the best learning source was the code of other extensions. After you installed an extension you'll find the complete source on your local hard drive. In XP it is located in "documents and settings\USERNAME\local settings\application data\Google\Chrome\User Data\Default" ... it's a little bit different in Vista and Windows7, I think.

There is a difference between plug-ins and extensions. Chrome extensions can be created using common web technologies like HTML and javascript. Plug-ins use an api called NSAPI and are usually being created using C/C++
