Good

Works with multi process Firefox. Gives you full control of what it blocks.

For example, this vid streaming site keeps creating popup windows which can't be blocked by this add-on: https://fmovies.is/

certainly can not block popups of openload.co

Good

It doesn't appear anywhere in the UI.

Popup blocker strict blocks many popups, but not all. There are some sites where advertisers have figured out ways to get past most popup blockers. Specifically on the test page Method 14/1, 14/2, and 17/1 goes through the popup blocker (I am using Firefox Developer Edition). Then on the settings page the checkboxes for the options are missing. Also clicking on the addons icon should not just turn it on and off, but bring up a menu to get to the settings page, disable for certain sites, enable, disable, and other options. It should remember settings for certain sites and there should be the ability to white or black list sites by clicking on the icon.

needs a setting to remember blocked sites
