AMO OpenSearch Engine per aminomancer

Firefox can generate an AMO search engine automatically by clicking a button at the bottom of the urlbar results while on cup.aihedy.com. This addon works exactly the same way but has a better icon with context properties so it can be made to look good with both light and dark themes, rather than always being bright cyan.
