Google Dork Builder
Google Dork Builder is an extension for Firefox with which you can forge your queries, save them and share them if necessary between your devices. It is possible to use the main operators from the sidebar or from the context menu after selecting text. Now it is also possible to retrieve the dorks from exploit-db.com.
