Too much unnecessary work... Rated 1 out of 5 stars
After using it for four months, I deinstalled this addon at long last, because I'm finally sick of it.
It seriously lacks a blacklist, which means requests you block all the time show up with every new site. And that's just tedious, because you always have to remember which requests you want to deny. Because when you go through the list to allow/deny, the list is completely mixed up and you have to pick and try one by one. As of now, I'm sick of having to go through the same trial-and-error routine on every second or third site just to have the site displayed as it should be.
There are similar addons like e.g. Ghostery where you don't spend half of the time to look if the sources and targets of a request are legitimate or not. And where you don't need half of the time to have a website displayed as it should be - instead of having a bit of text on a white background.
This addon means too much work and too much inconvenience for far too less benefit. So, after wasting very much time and effort for four months, I'm done with it.
