Rumors are already starting about the kind of features that Opera 9 is going to contain. Many of the rumors say that it is going to be thumbnail images when hovering over tabs as well as widget compatibility. The screenshot above shows the thumbnail hovering feature which isn’t a new concept in the web browser world. Firefox has already had an extension for quite sometime now that will allow you to show a thumbnail when hovering over a tab: Tab Preview. The widget feature may prove to be a successful add-on if implemented correctly.
