Great extension, even while to truly take advantage of it it is not as straightforward, still has an easy mode , but the real power comes when you use it in advanced mode, I saw some user in a review complain about not hiding some elements, but has ublock AND adblock at same time, this is not good and does not increase protection only decreases performance, and might even be the source of your problem so, dont use those 2 together, in fact, don't use adblock plus at all.
