It's great to finally have an extension option for connecting to ProtonVPN, but it seems to be a little buggy.

Every few minutes I get another notification saying a VPN connection has been established. I can turn off notifications, but it seems for whatever reason it is losing and reestablishing connection every few minutes, but doesn't provide any information as to why that's the case.

Unfortunately quite frequent reconnections, visible on the popup, which I quickly turned off.
The super-fast connection at browser start or after standby or hibernation should be emphasized positively in any case. Clearly better than the Windows app by a large margin.
If you need Killswitch, you have to use the app for the operating system, the browser extension does not have that.
Split tunneling also works very well: Now I don't always have to switch browsers for my online banking page, for example.

Proton rocks, top notch service, I use every one of their products, and am not dissapointed at al, and I'm a retired network admin and sysadmin with a huge focus on security, as I worked for a CLEC phone company.. Highly recommend

It's nice to have a proton vpn extension. However, after successfully conneting, all traffic in the browser is blocked by the company firewall. The extension needs measures to circumvent blocks, otherwise is useless in most relevant cases (or countries).
edit: secure core is blocked too. Using the proton desktop application, only stealth protocol is able to connect

I'm not a 'heavy' user however this add-on works perfectly for me. I'm really enjoying being able to tunnel my browser traffic through the VPN whilst keeping other traffic open (e.g. logging in to my workplace's email server) at the click of a button. This is perfect for me, and when I need a little more grunt then I can just jump over to the desktop client etc.

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.
