Both desktop & Fennec implement a unique id per tab, exposing this via the Tab class in the high-level tabs module would be a win: * some uses cases could be simplified if a specific tab can be uniquely identified http://stackoverflow.com/questions/4997818/firefox-get-unique-id-of-tabs-for-extension-development http://stackoverflow.com/questions/12495258/identify-drag-of-tab-into-new-different-window http://stackoverflow.com/questions/8098580/identify-tab-that-made-request-in-firefox-addon-sdk * chrome has it: http://developer.chrome.com/extensions/tabs.html#type-Tab

I test the commit but there a problem: After move the tab to other browser window, the id not the same. The Chrome document say: The ID of the tab. Tab IDs are unique within a browser session. I think it's better to keep it same in the same session like Chrome, not only in a window.
