Add custom search engines to your browser easily with Mycroft
For Firefox and Internet Explorer, this means you can search just about every site in existence from the Search bar in the top right corner of your browser. For Chrome users, this means you get even more functionality from the uber Omnibar.
Incidentally, Chrome users, did you know that you could use specific search engines from the Omnibar? When you grab a search plug-in, make sure you provide a keyword. Make it something short -- like 'pb' for Pirate Bay or 'imdb' for IMDb -- and then, when you want to search The Pirate bay, just type pb, followed by your search term.
While we're on the same topic, in Firefox, you can do something similar with Smart keywords.
