I was wrong on WebExtensions

WebExtensions > legacy addons.
Firefox legacy addons basically have unrestricted, full access to everything browser does.
They are barely step behind ActiveX. They can download arbitrary data and execute it.

But this is good. Allows for more powerful addons.

Troll post. Usually you don't willingly download ActiveX extensions like addons, and ActiveX gave more access.
