This is the rating I would give if it worked. I am in russia, and this thing requires a website sign-in, which is region blocked. (or firewalled or whatever). So it's a vpn that you can't acess without a vpn. I could get this on mobile though, I don't know why it doesn't allow to do so on pc, but on mobile this thing is awesome. But mannnnn, please fix this for russia, and make a sign in an app thing, like on mobile, or something. It's such a shame that it works so good, but only in parts.

放置していると勝手に切れてしまうからだめー

Unstable connection from time to time

In my view, it would be beneficial to rename this extension as Proton Proxy to prevent any misconceptions about its effectiveness compared to the Proton VPN app.

очередная нерабочая шляпа в рф

Hello,
I get a 400 error when i'm trying to log on the VPN threw the firefox addon
Here's the details of the error

Bad Request
Your browser sent a request that this server could not understand.
Size of a request header field exceeds server limit.

Requires a sign-in on a page that is inaccessible without a VPN. You literally need a VPN to use this VPN.

Also glitches out and asks me to update right after the installation, with no updtae available.

Undecided, I was wondering if there is a way to have split tunneling with just 1 tab on my firefox? So let's say I want Xbox website to see that I'm from USA but all my other tabs I want normal ISP service from UK, is that possible?

This doesn't seem to let me connect to USA, it's fixed to netherlands...

Update-
Would be nice if we could pick servers for free, not all of us are rich you know but thanks for giving something at least

Update 2-
I've had to remove a star because it is near unresponsive on windows 7 edition firefox 115extended build

This could be better if it worked properly and let me choose the server because others allow free server choice and more choices. If I like it I might buy it but not paying for subscription if its broke and doesn't let me test out free for long time like Avast antivirus has done since the 90s and I bought their product after a decade

the extension does not work at all

The linux app for proton has not received a proper update in years.

I have their paid VPN. The browser version of Proton VPN is limited. It's sad. I don't like talking like this because I like their service and speed, but there are so many things missing in all their apps, such as the Windows version, Android version, and the one in browsers.

Split tunneling is lacking on all devices and none have the same features. The one on the browser has the one I want, by website, but you can't include. As in, if you only want it to run on that website. You can only exclude so that it doesn't run on that website.
The one on Windows doesn't have website but IP or apps. You can include/exclude there but we desperately need the ability to add websites there and to decide per website/app/IP if we want to include or exclude. Same on the browser extension. Same on Android.

Here in Firefox, it's also missing a favorites list and the ability to choose a default. Same on Chrome/Edge. All 3 of their apps/extensions look different and behave different and have different settings. Really bad design.

None of our settings sync so you have to set it up each time in every browser, phone, computer OS.

Missing other information and settings.

Considering the number of clients they have, servers, and money they're making, they should easily have the budget to improve and streamline them all.
Will edit review after they update.
