commit 3011ced1077d4e8afd84642ff7942d236d78db34 Author: Alex Catarineu acat@torproject.org Date: Thu Feb 13 13:24:33 2020 +0100

Bug 28005: Implement .onion alias urlbar rewrites

A custom HTTPS Everywhere update channel is installed, which provides rules for locally redirecting some memorable .tor.onion URLs to non-memorable .onion URLs.

When these redirects occur, we also rewrite the URL in the urlbar to display the human-memorable hostname instead of the actual .onion.
