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.

Fastest porn blocker I've ever used for my kids.

may Allah reward you

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.
