Google has been testing search-enabled tabs in Chrome since December, but you've had to run test versions of the browser to see those tabs in action. That changes today: the company is expanding its trials to include a small number of users running stable copies of Chrome and Chrome OS. If you're part of that exclusive group and use Google as your default search engine, you'll see a search box appear in every new tab. The page also supports other providers through a developer API. While Google doesn't say if or when the new search feature will reach every Chrome user, it notes that previous tests have been "encouraging" -- don't be surprised if your tabs get the same treatment in the near future.
