This is a great and very useful add-on! Thank you to the author!
This add-on was inspired by the Piro's (piro_or) add-on. However at Piro's add-on, the option "open everything in new tab"... it really means that! With this option on, for example at facebook.com even new notifications or messages, everything will open in new tab. Sadly, this is not happening with this add-on.
To the author, please, add Piro's add-on behavior, allowing to open everything in page, as a new tab. If is on the option "everything in new tab", then everything must open in new tab.
