commit af92504dc26134f2250c6c52a2ce5645afdb4ff6
Author: Alex Catarineu <acat at torproject.org>
Date: Thu Mar 5 22:16:39 2020 +0100
Bug 21952: Implement Onion-Location
Whenever a valid Onion-Location HTTP header (or corresponding HTML
<meta> http-equiv attribute) is found in a document load, we either
redirect to it (if the user opted-in via preference) or notify the
presence of an onionsite alternative with a badge in the urlbar.
