How many times have you found yourself looking for information on the web with tens of tabs open? 
This extension allows you to hover briefly on (almost) any link in any web page to preview it in the right bottom corner of your screen.

Please, note that some websites cannot be opened in iframes due to security measures. I intend to host a database containing every exclusion so that you won't have to update the extension every time.
