Chrome: Got too many tabs open and don't know where to start? Relevance is a free Chrome extension that reorders your tabs based on what you've read and which domains you visit most often.
Relevance tracks the pages you actually read, and keeps all that data locally stored without sending it to a remote server. Once it understands your reading patterns, you can activate it to change your current tabs' order so that the sites you are most interested in are at the start, while things you haven't read at all are at the end.
It's a simple way of dealing with tab overload, especially if you're short on time and have a lot of links open.
