Due to a bug in Firefox's implementation of WebExtensions, we can't inject scripts into pages with the CSP 'sandbox' directive set (unfortunately this means that this extension won't work on files hosted on raw.githubusercontent.com/*, or any other page with CSP 'sandbox' enabled).

After some investigation it looks like this is a known issue and the bug reports can be tracked here and here.

For reference:

This page works (no CSP)
This page doesn't (CSP)
