Productivity Sauce

Despite its somewhat awkward name, Searchonymous is a really neat Firefox add-on that anonymizes your Google searches. It does this transparently, leaving your search preferences intact and keeping you logged in to other Google services like Gmail and YouTube. According to the developer, the add-on does this by blocking certain Google cookies and generating randomized ones that can't be used for tracking. At the same time, the add-on keeps cookies that contain your search preferences. Searchonymous also disables cookies that display the ads on Google's main page. In addition to that, Searchonymous can be installed without restarting Firefox. So what's not to like?
