This is an extension created to allow users of Waterfox Classic (and possibly other Firefox derivatives) to load polyfills at will.

Currently available polyfills:

• ResizeObserver
• Webcomponents
• BigInt with slight modifications (there is no way to actually polyfill BigInt as it's a new type that needs internal operators to work with it, if website creator used JSBI properly everything should be fine, in other cases it will likely break anyway)
• AbortController
• Array extensions bundle
• ArrayBuffer
• DataView
• Element extensions bundle
• es2018 bundle
• es2019 bundle
• globalThis
• Intl extensions
• Promise.finally
• String extensions
• TypedArrays

This extension uses libraries:

• Text Encoding with a slight modification to override built in encoder, otherwise it wouldn't be possible to encode text to charsets other than utf-8

Licensing information regarding included polyfills is included both in repository and in package in legal directory
