I just have the trial version... I'll know soon if I receive news from "hadopi"...

Very, VERY aggressive. I mean, it does a good job alright, but be warned, this thing blocks pretty much EVERYTHING! Even when you turn it off, it still blocks EVERYTHING! You have to disable the extension to stop it from blocking everything. For example, my CamelCamelCamel price tracker extension won't work then this is enabled. Any sort or icon or link for a social media site will disappear. I would only recommend it for advanced users because having this installed will cause a lot of confusion for average users.

I mean, if you want something that REALLY goes for it in privacy, then this is, but be prepared to disable this if you get strange behaviour with other add-on extensions or websites.

nice

Good, I can say for now .
I have not really seeing what I wanted, though still trying

Hace su trabajo de VPN pero inhabilita subir fotos a Instagram directamente desde el navegador. Para subir fotos a Instagram debo deshabilitar esta extensión y activarla sólo cuando necesito conexión por VPN. Si corrigen esa falla les doy las 5 estrellas

Can randomly enable itself after restart of the browser even if "load on startup" is disabled, and it can cause trouble with some websites which do not take kindly to the usage of VPN.
So I keep the extension installed but disabled most of the time, and enable it only when needed.

I love this add-on and the service behind it. I can't live without it. But this add-on (version 3.1.4) is very quirky. It does not reliably connect or disconnect on my command. Sometimes, it connects to the service without asking me. Sometimes, the connection drops when I need it connected. I suggest that once you've disconnected from the service, disable the add-on as well. Re-enable it when you want to connect again.
