This plugin allows you to use a key combination and click to open a link in an incognito window. If you open links incognito several times a day, this plugin can be a great time-saver.
The default key combination is Shift + Meta + Click. It can be changed via the Options page. Whether the new tabs open in a new window each time or in the same window can also be configured.
The Meta key could be the Command Key (on Mac), the Win Key (on Windows), Context/Menu Key (on Linux) or any other system determined key.
