Mozilla community member Vincent Lefevre reported that on Linux systems, web content can access data saved to the clipboard when a user attempts to paste a selection with a middle-click instead of pasting the selection content. This allows for possibly private data in the clipboard to be inadvertently disclosed to web content. Windows and OS X systems are not affected by this issue.
