The actual ProtonVPN service itself is definitely 5 stars, but unfortunately this add-on has a few glaring issues that make it borderline unusable:

- The connection will randomly drop and reconnect. Obviously for a VPN extension, this is a pretty critical failure and needs to be addressed ASAP.
- Compounding this, as far as I can tell, there is no "kill switch" option at all, so if the tunnel loses connection then your web traffic leaks to your ISP.
- When the extension randomly drops your connection, if you have the "Secure Core" option selected, it will not reconnect via Secure Core and instead just directly reconnect to the fastest server.

Additionally, it would be nice if you could enable some free servers for those with non-premium accounts, but I recognize that you're running a business and the extension is meant to be a value add for paying users. Having said that, however, the extension itself is critically flawed, and I would recommend users instead use the desktop version of ProtonVPN and tunnel your web browser's traffic through it instead, as it at least has a functioning kill switch option to help prevent leaks.

We are required to login account, impossible to share my account with my friend access this extension.
I share my account with my friend, he only has access to the ProtonVPN client, but with this extension it is not possible to share with him.

very good

Абсолютно не работает в бесплатной версии. Зачем обманывать людей! Зря только время потерял на установку на Arch Linux и на расширение.

Aucune possibilité de connexion sans abonnement payant alors que l'app Android / Mac/Windows propose des serveurs gratuits .

This is my first addon review ever.

I give it 1 star, because at the current time it has no use for me. It's paid. You get nothing free. I suggest to make it at least 10 minutes/ 1 hours a day free vpn.

If you add free stuff, I will edit my review

Smooth, simple, recently expanded service offers. Minimal but functional use at a free level, expanded options for paid users.

Very good VPN. I've been a Proton user for years now.

Hello, I thought Proton VPN was a libertarian socialist, I wouldn't have expected it to make an add-on for paid users.

Great idea, quick and easy to use...but unfortunately highly unreliable. It keeps disconnecting regularly after a few minutes (<5) without clear reason and without any indication. You are now forced to 1) add the add-on icon to the toolbar and 2) keep an eye on it at all times.
