I've followed Creating a Content Blocker, and my content blocker runs but doesn't work (i.e. pages load in Safari), even if trigger url-filter is ".*" and action type is "block". There's "No Active Content Blockers" in Preferences, where I'd expect to see mine. Is there a common solution to this problem?
Also, I had to set this post's "place/space" as Safari Extensions because there was no Content Blocker option.
