Changes
---
- added ability to edit match patterns for existing rules (#76)

Overview
---
This extension allows users to selectively allow different hosts on the web
to have access to different types of browser functionality. Doing so allows
security and privacy sensitive web users to limit the attack surface presented
to websites, and to limit websites to the functionality they actually need
to carry out user-serving purposes.


Background
---
Web browsers gain staggering numbers of new features, without their users
knowing what new functionality is being pushed into their trusted base.
While some of this functionality is broadly useful for things commonly thought
of as "web" related, a large amount of it is useful in only rare situations,
if ever. Examples of this rarely-needed functionality includes the
low level audio synthesis capabilities of the [Web Audio API](https://webaudio.github.io/web-audio-api/),
the low level graphics capabilities of [WebGL](https://get.webgl.org/),
or the light sensing capabilities of the [Ambient Light Sensor API](https://www.w3.org/TR/ambient-light/).
Such complex-but-rarely-used functionality has been often used in attacks
on the security and privacy of the web.

Other functionality is frequently used by web sites, but for non-user-serving
purposes, like fingerprinting anonymous users and tracking them across websites.
Examples of such functionality includes parts of the [SVG API](https://www.w3.org/TR/SVG/),
parts of the the [Canvas Element](https://html.spec.whatwg.org/multipage/scripting.html#the-canvas-element)'s functionality,
and the [Beacon standard](https://www.w3.org/TR/beacon/), among many others.

This extension helps users stay private and secure online by limiting websites
to only the functionality they need, and prevent them from accessing rarely
needed and/or privacy violating functionality.


Functionality
---
The extension currently includes the following functionality:
* Creation of domain-specific functionality rules, based on host-matching
regular expressions.
* Blocking of functionality across all domains, with a fallback, "default"
blocking rule.
* A novel method of blocking functionality, designed to minimize the effect
of removing functionality on existing code that expects that functionality
to be in place.
* A categorization of approximately 1,400 JavaScript methods into 74 different
Web API standards (and, where appropriate, sub-standards).
* User feedback to alert users how many hosts are executing script every time
they visit a site, to ease the creating of new rules.

The following functionality is not currently implemented, but is being considered
for future inclusion:
* The ability to subscribe to blocking rule sets created by trusted third
parties, similar to the EasyList / AdBlockPlus model of rule subscriptions.
* Blocking property accesses on non-global structures through an additional
level of interposition on runtime created objects.
* Adding new Web API standards into the code base.
* Extend blocking to properties and events (currently only functions and
methods are interposed on).
