Review for Silent Block by Elliott
Rated 5 out of 5 stars
Thanks Schuzak, this is exactly what I was looking for!
I found documentation / examples here:

If you're using an alt directory for configuration files (you can do this by setting extensions.silentblock.altdir, and you might have to do this if you don't have a rooted device), you will need to enable the "Storage" permission for Firefox. Otherwise, silentblock will not be able to read the configuration files on startup.
To create your own collections, you must have a Mozilla Add-ons account.
