Idіоts complaining that the service whose infrastructure costs millions of dollars isn't offered for free. Have you intellectual amoebas heard about saying "If something's free, you are the product" ? Is 10€/$ a month such a burden?

Sono un cliente pagante. Installato e fatto funzionare su varie macchine sempre come add on di Firefox senza alcun problema. L'unica cosa che succede di tanto in tanto e' che gli IP che usa sono stati messi in black list precedentemente, e quindi devi collegarti su altro Paese e riaccedere al sito.

I like it. I do see a lot of 1 star reviews where people say they are annoyed it's not free. That seems unfair criticism. Potentially Proton is misleading people into thinking it's free. That is unfair. But overall, I've had a good experience with Proton VPN. Suits my needs for a global VPN.

The extension is a must have. It currently has a small bug related to the disconnection of the account which happens randomly but I think it's gonna be fixed soon, since Proton Team already acknowledged it. It doesn't leak, it's pretty fast and it's super easy to use. Good job!

It simply works. Automatic (free tier) server connection and it gets the job done, without leaking anything

While I lack sufficient experience using the "add-on" to give a quality review of it, I will say that as a subscriber/user of Proton VPN and the services, to which I've been paying for over the past year, have had one or two minor issues, which I have managed to resolve, but aside from that, I am satisfied, and happy with Proton VPN. (So far) I've tried 3 or 4 other (paid) popular VPN services, which I discontinued, after either having issues with their policies and/or after having researched them. Proton is my choice.

Best VPN
