The LinkChecker extension provides a great service to me. At one point, when I started looking at this extension, I thought it would spider all of my links on my site and let me know the status of them.
If you have a page full of links that is 12 pages long, this extension is for you.
Install the extension and browse to a site that you enjoy and has a lot of links. Click under Tools and click Check Page Links. LinkChecker will display all of the links on the page in a certain color to represent each links status.
- Red - Broken Links
- Yellow - Forwarded, Forbidden Links
- Green - Good Links
- Gray - Skipped Links
LinkChecker even has a toolbar button. Right-click on a toolbar and click "Customize..." The button is called "Check Links" with a big blue checkmark ("Ya can't miss it!"). Drag that toolbar button onto an existing toolbar and your off and running.
I thought I wouldn't need this extension at first, but after looking through the site, I've noticed I had some dead/bad links in the my pages. As I've said before, it doesn't have the ability to move through multiple pages, but that's what the other maintenance sites on the web are for. :-)
The extension gets a rating of 4/5 because of its usefulness. If you are working on a directory listing or a portal application, this extension would be extremely valuable to you. Literally, at the click of a button, you could find out if the external links (or internal for that matter) are dead or not.
