I have always been satisfied with this supplement and I have used it for many years. Recently, however, it has begun to negatively affect the behavior of Firefox by the fact that, for example, on the website www.czc.cz it was not possible to scroll the page down. I had to remove the add-on and now use Ninja Cookie to block cookie dialogs.
Try reporting czc.cz using the "report" link in extension's menu: you'll see I'm aware of the problem and it will be fixed soon. Btw, you don't have to uninstall the extension just because of that: you can whitelist that website until it has been fixed.
