The first program I open every day is Firefox, and most days the first Web site I visit is Google. That's why I'm glad so many Firefox add-on developers have created tools that give me a new perspective on my Google search results. Here are three of my favorites.
Sharpen your searches with GoogleEnhancer The primary reason I click Google's Advanced Search option is to limit the results to a specific date range. With NettiCat's GoogleEnhancer add-on I can narrow my searches by date as well as by file type and a handful of languages via drop-down menus that are placed to the right of the search box.
As nice as the search enhancements are, one of my favorite GoogleEnhancer features is the addition of icons to the left of the results for each link's site. The add-on also numbers the results, though these don't really add much to the results, in my opinion.
