Just wanted to point out that the Privoxy package for the Opal has a file labeled match-all.action.new in /etc/privoxy where the default configration uses match-all.action as the file name.
An error message is displayed about the missing file when configuring Privoxy using luci-app-privoxy.
After installing privoxy and updating listen address and permit access IP’s under access control, the error message is displayed that match-all.action is missing and will not apply the changes.
SSH’ing in and looking at /etc/privoxy showed match-all.action.new in the directory on a fresh install. I did not restore a backup and just configured the Opal from scratch.
