I've been waiting a long time for an ezLinkPreview type of addon for FireFox and it has finally arrived. Unfortunately, it's missing one essential feature so I can't give it 5 stars. It needs a close button! Yes it closes itself after a certain amount of time but this waiting time seems to vary and sometimes it takes forever. Just add a close button. It's a good start though. Thanks to the developer.

EDIT: My request has been fulfilled! I've updated my review to 5 stars. Thank you Lecron!

EDIT2: Would it be possible to add a shortcut command for opening the preview window? For example ALT or MOUSE 4 and click on a link would open a preview, the CTRL LEFT-MOUSE which opens a new tab comes to mind. A similar command could be used to more easily close the preview window.
