Simple search in Firefox
This add-on can turn any word on any Web page into a search query on multiple search engines
One cool thing in Firefox is the capability to highlight a word, right-click, and search your default search engine. But that just gives me a general search. I swear I've seen the woman who plays Charlotte on "Lost" in some movie. I'd rather be able to right-click and immediately search IMDB. Here's a Quick Tip for adding multiple search engines to the context menu in Firefox. Watch the video to see how it works.
Go to addons.mozilla.org and search for SimpleSearch. While it's still in the experimental stage, you'll have to log in to use it.
After you've installed the add-on, go to a page on the Web and highlight a word. Right click and highlight the search option.
Choose the search engine you want.
And you'll be taken to that search.
