Yavaş.

Blocks just fine, except I can't seem to adjust the settings for what to block.

exactly what I needed, it doesnt just dumbly block pages it actually actively searches for the explicit content on ANY website even google images and only blocks the page completely if there's too much things to block.
Howerver, the settings dont seem to work and there should definitely be a whitelist option because it causes extremely high memory usage, and it's even more annoying on websites such as youtube that litterally becomes not usable even though there is nothing to actually block.
I'll change my review if the add-on is updated but right now I just cant use it.

may Allah reward you

It blocks quite well. I'm amazed by how it can filter all photos in even on Facebook and Instagram. Highly recommended!

Slowly removes images 1 by one. So you actually see them anyway. Completely useless. Also not customizable.

It blocks like everything that has porn in it which is great. For sites like reddit it does not work but there you have other add-ons to do that job.
