In chrome, when you move the mouse over a TAB that isn't in the foreground, it displays a small preview window of the TAB a few seconds later to help you view the TAB, rather than just showing the title and not being able to tell what the TAB is
You know what this would be a very good feature to have well I made a thread about some things to so yeah I wonder if Mozilla is testing our ideas in an experiential version of the Firefox Web Browser?
@JonJ Will these features get into Firefox cause they would be good to have.
