Can Lynx activate this feature at all? Lynx may have bookmarks, but as far as I can tell, Lynx does not have WebRTC support, which means it can not be exploited to share private LAN IP addresses, nor can it access web cams.
Firefox, like Chrome, is going overboard with non-web-browsing features. Some less technical users surely will appreciate that, but at some point it becomes less of a browser and more of a pseudo-OS.
If people don't voice their opinion against this direction, then Mozilla will continue down this path. I don't think it's too much to ask a web browser to be a web browser and nothing more.
I am also against webRTC, I don't think it's mutually exclusive. Mozilla is signalling with this that they're looking to push applications that leverage their feature-set.
