Do you use OpenDNS?
I have for awhile, since my ISP’s DNS servers can be kind of flaky sometimes. The one thing I don’t like about the service is how it hijacks mistyped domains and I’m Feeling Lucky searches that Firefox would usually redirect to the site I’m looking for, sending me to an OpenDNS search page with some ads on it. Sure, it helps support the service, but as a Firefox power user, the added time-waste is frustrating.
Luckily there’s a solution. The Feeling Lucky Fixer extension for Firefox restores the functionality to the browser, allowing you to simply type a website’s name (e.g. “imdb”) into your URL bar and wind up in the right place. Huzzah!
