I'm very pleased to see that support for "Fossils" are banned.
The add-on seems to work fine

We can build a cleaner, healthier, safer, fairer future for all - but fossil fuel companies & their financial supporters are still standing in the way. Until they adopt ambitious fossil exit plans, it's 🕚 to block them and their greenwashing out.

Finally a way to block out fossil fuel companies and their financial backers from the digital space. When will you be adding more coal, oil and gas companies? Add them all!
