title: Is there a way to uniquely identify tabs for the lifetime of the tab?
body: <p>I was thinking of using the tabid to do this, but it seems to change quite often as I am browsing around within the tab. The <a href="http://developer.chrome.com/beta/extensions/tabs.html#apiReference" rel="nofollow">API reference</a> notes that the tabid is unique within a "browser session". I took this to mean within the lifetime of the browser process, but it seems more likely now that uniqueness is only guaranteed during a session with a specific website. Is there another way I could uniquely identify a tab for its entire life?</p>
