[tor-commits] [tor-browser/tor-browser-91.0b5-11.0-1] Bug 21952: Implement Onion-Location
commit ef4c6aafebf9f61b9c9bd01c6e751b50b67bf9fb
Author: Alex Catarineu <acat@xxxxxxxxxxxxxx>
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.
