There's a built-in blocker-mode
that blocks the ads and tracking hosts, and noscript-mode
that disables JavaScript execution.
You can toggle these modes with the help of auto-mode
(read on it there), so you won't need to manage modes manually.
Some additional tracking and ad-blocking features (like recent Intelligent Tracking Prevention from WebKitGTK) are in progress too, so stay tuned :)
Alright, point-by-point:
force-https-mode
.proxy-mode
?All in all, we're getting there :)
