My recent changes towards more privacy friendlier life

There are two mechanisms at play here: 1. URL redirection in your address bar, from youtube.com to invidious-instance.org 2. Embedded redirection, when navigating within third-party websites The former is what is the primary use case for LibRedirect, but embeds are a separate case. The term “target site” is ambiguous and could mean two options: 1. The main site, AKA, YouTube 2. Some random third-party site that uses YouTube embedded videos (or other embeds supported by LibRedirect) The latter is not covered by default, it is opt-in, so for example, on Privacy Guides, if someone embeds a YouTube video in a topic, it will not redirect to an Invidious instance unless you have configured it to also redirect embeds as well.
