The problem with ublock is that when you try to block an image:
For example, I don't want to see recommended videos at side of youtube. I click the elements that make the text (Like video title, views) and it works!
But when i click the thumbail of the recommended videos uBlock automatically blocks the SPECIFIC image (image url) and not the html element
So when a new recommendation video is loaded it is not blocked, because the url is different
