Hi Aaron, thanks for your support.
Unfortunately I cannot find a way to distinguish (handling onbeforeunload or unload events) if the user has clicked on X to close the tab, or the page in unloading to other reasons (page change, new urls...). Do you know how this events can be distinguished? I need to avoid the tab close only when the user is trying to close it with the X. If I can solve this issue I think that the "SaveTheLastTab" extension can be realized, otherwise I think it's impossible with current APIs. As you suggested I wrote a Feature Request regarding the possibility to prevent default action in Chrome event handlers: http://code.google.com/p/chromium/issues/detail?id=30198 I think that this feature will be very usefull for all event handlers. For example the can be also the need to prevent a page change when a specific-url is clicked and so on...
