Firefox 41.0 comes with two plug-ins pre-installed: "Open H.264 Video Codec" by Cisco and "Primetime Content Decryption Module" by Adobe Systems. Common third-party Mozilla plugins include Adobe Flash Player, Acrobat Reader, Adobe Shockwave Player, Java SE, QuickTime and RealPlayer. Unlike other types of add-ons, Mozilla does not distribute plug-ins, and the add-ons manager cannot update them.[27]
