Mozilla isn't just rethinking its choice of default search engines in Firefox; it's overhauling the search bar itself. An upcoming version of the web browser will let you search a specific site with one click. If you want to find an ancient Twitter update or scour Wikipedia, you won't have to wait until you get to the search results to take action. The update will let you add other sites, too, such as your favorite restaurant recommendation page. You can argue that Firefox is catching up to Chrome, which lets you type the site you mean to search, but it's hard to object to anything that helps you get to what you wanted a little bit sooner.
