The ThunderBrowse Thunderbird extension adds a URL bar to the Thunderbird interface, thus allowing you to be able to view Web sites without having to open browsers.

ThunderBrowse is a unobtrusive because it doesn’t require you to add any more buttons to your toolbar, as it adds to the message preview pane without taking up much space.
