Notably:
- Import logger improvements from uBO
- Import CNAME uncloaking from uBO
- Import more improvements from uBO
- Make use of modern JS features
This should un-stall further development of uMatrix.
Related issues:
- "Requests bypass uMatrix on Firefox start"
<https://github.com/uBlockOrigin/uMatrix-issues/issues/69>
Using same approach as with uBO:
https://github.com/gorhill/uBloc/commit/41548be6be35
`suspendTabsUntilReady` advanced setting added to "More" pane,
useful only for Chromium -- the blocking of early network
requests is enforced unconditionally on Firefox (because it
supports returning Promises from webRequest handlers).
- "Cookies leaking temporarily"
<https://github.com/uBlockOrigin/uMatrix-issues/issues/74>
Changes in the webRequest API in Chromium 72+ caused uMatrix
to fail to process `Cookie` and `Referer` headers on that
platform.
