Chrome: If you're the type to have a lot of tabs open in Chrome, you know that searching through them can be a pain. Chrome Tab Search makes things a little easier by adding a Spotlight-esque overlay to search through open tabs.
To pull up the search page, you just hit a keyboard shortcut (Ctrl+O on Windows or Ctrl+Cmd+O on Mac) to pull up the search. Type in your search query, and Chrome Tab Search looks through all your open tabs. Unfortunately, the search is restricted to the page's title, and you still have to use your mouse to navigate to the page, but it's better than nothing.
