As = RMS recently pointed out, we should have something like = Libre.js

I plan to implement that idea, but I have = some design choices and
would like to hear inputs = from you guys.

There are two obvious options to achieve this:
1) Implement (part of) the Web Extension API
https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExt= ensions/API
and let libre.js runs as-is in = Emacs.
2) reimplement libre.js as = libre.el

Both = will require adding primitives to Emacs C source to expose
urlRequest events, etc.

Option 1, besides enabling libre.js, = can also bring numerous existing
cross-browser = extensions to Emacs, if we finally support a large enough
portion of the Web Extension API. However those extensions = are
all written in JS and JS is worse than = Elisp.

Option 2 might require as much work as option = 1, but without the additional
benefit (or drawback?) of = bringing other JS extensions.

What do you think?

Best,
Qiantan
