Firefox no longer includes Hello. Hello only used standard WebRTC APIs, so anyone could create a comparable service as a regular website, such as Talky.io.

Extension signing can be disabled in about:config, but I think the pref ("xpinstall.signatures.required") only works in the Firefox Nightly and Developer Edition channels.

EME DRM is enabled by default in Firefox, but it won't work until the DRM blob (Google's Widevine CDM DLL) is automatically downloaded about one minute after Firefox launches. Here are instructions for disabling EME DRM and uninstalling the Widevine CDM:

Unfortunately that is no longer true. Their argument was that users could be tricked to disable it, or run extensions that disable it. So to cater to the lowest common denominator user they completely removed the option for all users of Firefox.

The alternatives are the non-Firefox (unbranded) Firefox builds or using an alpha version of Firefox (developer version).

Thanks for the information. I've been running only Nightly for over a year now and hence my misinformation. That logic does seem sound though but would be better implemented if any change to any preference that's not visible in the Preferences section raised a notification about it. I think I'll add this to Bugzilla.

On the non-beta version? It's not supposed to be toggleable.
