Worthless to me as well. Why can't it fix urls like mozilla.om? It never catches those. And I can't remember EVER entering .con rather than .com. Without the ability to customize urls to fix, it's useless in my browsing.

This review is for a previous version of the add-on (1.6). 

Because...

Because mozilla.om could be a valid URL. .om is a valid TLD, just like .com.
