Bug: when the parameter "&addonversion=4.1.4" is added inside the search URL (by this very addon) then Ecosia does not display all result category, nor the 2 leading adds in the search results. Namely, the Image tab is missing. When I manually delete those, then the tabs and adds come back.
Also, the fact that you choose to make the two leading adds in the results far bigger than the rest makes me want to use my addblocker on ecosia.org...
