Rated 5 out of 5 stars

Perfect tool: Places a tiny icon to the right of a hyperlink and displays a preview when you hover over it with no risk of launching it by accident. The preview popup is placed perfectly not hiding too much of the screen.
I very much like the warnings displayed when the link target looks like a risk, e.g. executing an action on access.

This review is for a previous version of the add-on (1.6.1.3).
