Rated 5 out of 5 stars

I've been looking for something like this for quite some time.

I am really impressed with the JavaScript.

It was interesting to browse to a recent article by Jeff Atwood at Coding Horror (http://www.codinghorror.com/blog/archives/001181.html) that talked about parens in URLs.

Linkification only had trouble with the URLs that end in a paren.

Great job!

This review is for a previous version of the add-on (1.3.5).
