Reluctantly I've uninstalled Adguard Premium and returned to uBlock Origin.I really wanted to like it but I just couldn't get on with it. A much heavier load than uBlock Origin, pages didn't load as quickly, and not very user friendly either. There were lots of niggling problems too, especially with Firefox, such as various sites not loading, youtube not working in full screen etc. A lot were to do with certification issues but after a while I got fed up having to rectify this. Just too much hassle.
