Newer FF versions come with two plugins that are automatically installed. OpenH264 Video Codec provided by Cisco Systems Inc Prime-time Content Decryption Module provided by Adobe Systems, Incorporated I looked into both plugins and do understand their basic function, but am not clear on how vital (or not) they are for browser function and more importantly whether or not they pose any security risks? #1's purpose is "to comply with the WebRTC specification and to enable WebRTC calls with devices that require the H.264 video codec." Since I keep WebRTC disabled by default can I disable it this plugin? #2 "allows you to watch DRM content on FF" and is an Adobe plugin. Do I need to treat it like risky Adobe flash and block it by default until I need it? Thanks!
