Review summary

Users praise Stop‑it for reliably blocking adult content, enforcing SafeSearch, and being lightweight. Major complaints repeated across reviews: it blocks YouTube and other legitimate sites without a whitelist, lacks password protection (so children can disable it), and has inconsistent behavior for some users. Request for customization (site exceptions/whitelist) is a frequent theme.

Pros

Effectively blocks porn/NSFW content and filters search results
Enables or enforces Google SafeSearch (including in private browsing)
Works across languages and blocks foreign-language explicit searches
Lightweight and easy to install, low memory usage

Cons

Blocks YouTube videos and comment sections unexpectedly with no way to whitelist YouTube
No whitelist/customization to allow specific sites (e.g., gambling or trusted sites)
No password or lock — easy for users to disable the add‑on
Sometimes blocks legitimate non‑explicit sites (reports include Coinbase and other useful sites)
Inconsistent behavior for some users — a few report it doesn’t work at all

2025-09-03	Fi*****	blocks youtube videos for no reason. no way to whitelist youtube. i would give it 5 stars if it would just block explicit sites and let me watch youtube.

2025-03-07	Fi*****	I wanted it to be good, and I gave it a fair chance. But this extension is actual garbage. It randomly blocks YouTube videos for no reason and at other times it blocks the comment sections of YouTube videos. Why? None of these videos are even slightly explicit. Kept happening for months. And beyond that it blocks actually useful websites, that again, have 0% explicit ontent. Websites such as Coinbase.com are blocked by this app. I have confirmed this app was responsible for all the above- disable the extension and YouTube and Coinbase immediately start working. Do not use this extension.

2023-04-17	Th*****	It would be nice to have an option to toggle the "delete search history & cache" option off and on. I just want the nsfw sites to vanish but want to keep my history and cache

2023-03-24	Pa*****	Bem, a extensão funcionou como o esperado: o SafeSearch é ativado, sites pornôs são bloqueados, e funciona mesmo que eu pesquise em outra língua, sem falar que não é possível desativar. É muito melhor que o antigo add-on que eu utilizava. Só que eu encontrei uma brecha. Quando se pesquisa pornografia nas redes sociais, a exemplo de Twitter e Instagram, elas aparecem. Solicito uma filtragem dentro das redes sociais, se possível. Ainda assim, este é o melhor add-on de bloquear conteúdo adulto, na minha opinião.

2022-05-19	Fi*****	I don't get it. The claims seems legit. So I installed it on Firefox for Mac and tried it. Got porn, no problem. Restarted Firefox. Got porn. Rebooted. Got porn. No idea what else I need to be doing, cause it's a pretty straightforward plugin.

2022-03-19	Fi*****	It works great but needs some customizing options. It blocked the porn sites even from coming up in searches except for a foreign one but it's not being https blocked it anyway. And it's great that it doesn't bring up a page saying it's being blocked like others do. The problem was when it came to gambling sites. I want a porn blocker for an old man with dementia so he doesn't spend literally all day looking at porn. He also sometimes spins FREE slots which is no harm but this blocked all of them, while still showing the search results, they just weren't clickable. I wish it was at least a little customizable so I could allow his favorite free site. Edit: one more thing to help those using it for children. Just right click the symbol in the menu bar and click remove from menu bar then the child wont know it's there. If they are old enough to realize something is up and go into plugins to disable it then they might be old enough to stop gate keeping but I'm not a parent. I think for actual children hiding it should be enough.
