A very good AdBlocker, blocks all the ads websites throw at it! One little con is that is makes web pages longer to load.

Very useful addon but unfortunately it doesn't work on pages opened in FF's Side Bar (e.g. using Side View or other addons that open web pages in Side Bar). Thank you.

Chose it over uBlock because of its AcceptableAds policy, which I found sensible.

Had to drop it and switch to uBlock because it has been opening an alert tab for a month at every beginning of browsing session, while it desactivated every settings I had for the addon.
