I found a neat little free program today that cleans up your bookmarks and favorites in your web browsers.

It works with Internet Explorer, Firefox, Chrome, and Opera.  (Too bad, I don't see a Safari option.)

Basically it looks at all the bookmarks in your browser, and tests each one to see if the page they point to is still working.  That way, you can quickly purge all non-functioning bookmarks you have. 

That would be handy enough as-is, but it also has a feature to go out to each bookmarked site and grab the latest "favicon" image to display in your bookmarks.  Sweet!

Did I mention the software is free?

It's called AM Deadlink, and it's located here: http://aignes.com/deadlink.htm

It seems pretty well built too, not just "thrown together".

Very handy for people with a lengthy collection of favorites/bookmarks.

Edit: Forgot to mention, it also finds all the duplicate bookmarks in your collection!
