About this extension

This addon allows you to control JavaScript API permissions at per-script basis.
You may use it to protect your privacy against fingerprinting.
Use options page to specify JavaScript API restrictions. Choose feature name, context (first-party or third-party) and permission level.

TL:DR; this addon may do the same things as WebAPI Manager, but at per-script basis.
