I installed an add-on but can't get it to appear on the add-on toolbar. Customise does not offer the add-on.
The add-on is the ad blocker. It is actually used in the demonstration of how the add-on toolbar works but I simply can't get it to appear there. I have re-started. Tried right click & customise. Disabled then re-enabled add-ons.
How do I make it available for use?
