 Firefox 60 ESR (the current basis of Tor Browser 8) officially doesn't
 support "legacy" browser extensions using XPCOM/XUL, only the newer
 WebExtension API.

 Tor Browser still includes some legacy extensions; apparently what makes
 them keep working is a [https://gitweb.torproject.org/tor-
 browser.git/tree/browser/app/profile/000-tor-
 browser.js?id=4d0f9fa5fdd5831fbc2e28cb6c7b1056bd4deeab#n265
 extensions.legacy.exceptions] pref (#26127; thanks sukhe for knowing
 that). I don't see where !meek-http-helper@xxxxxxxxxxxxxxx is being
 allowed (edit: probably a [comment:4|source patch], thanks mcs), but
 somehow it is still working too.

 Assess whether it's possible to rewrite the helper as a WebExtension, and
 do it if so. Ideally it will be possible to keep 100% compatibility with
 the current helper interface; but changing meek-client and meek-client-
 torbrowser is also an option.
