@mapx Thanks for your reply, so it is not possible with an addon like AdBlockPlus and I guess I will have to use Greasemonkey if I want to hide an element on a specific page URL.
I don't have an example to share since it was a private page but using a simple filter like example.com##.someClass was not enough in my case because the element was hidden on every page and I wanted it hidden on one page only. I also checked if the page could be hidden with a distinct selector but I did not find one.
Do you think the feature to hide an element on a specific page URL could be added in a future version? I am not the first one interested in this feature (https://superuser.com/questions/1272205 ... block-plus
