В России не работает. Ищите другое расширение. Хлам.

I am a Debian user. I also use Proton Pro. After trying many services, I settled on Proton because I have a lot of data to protect in a trusted cloud storage service, and I use my own domain for my personal email through Proton Mail. Proton VPN is included, and I am very satisfied with it. It never fails, either as a Firefox extension or as a VPN app.

Actual dead weight for my browser, this extension seems to only work when it wants to and its not often it does. I'm constantly fiddling it because it'll randomly stop working completely and make me lose access to the internet.

Fast, reliable, and easy to use

I’ve had a great experience with Proton VPN’s Firefox extension. It’s simple to install, quick to connect, and works reliably without slowing down my browsing.

My normal connection is around 950 Mbps download and upload, and I typically get 800 to 900 Mbps when connected to a premium Proton server in New York City. That is excellent performance for a VPN.

Proton VPN also works across all major platforms. Proton Unlimited, or Proton VPN Plus with Proton Pass, offers great value for privacy focused users. Overall, it’s a fast and user friendly VPN that I’m happy to recommend.

Does not load, constant spinning circles.

Four stars because I've used this for years without any hiccups, not five since it has been days since I have been able to use it on any Firefox-based browser. Works fine on Chromium-based browsers. This is important and needs to be fixed yesterday. People might be browsing the web without any protection, since they don't realize their connection to this VPN has been lost for so long now.

App is Silently Crashing constantly while in use. The icon on the toolbar will be lit up green like it's connected and working fine, but no website will load, so I'll click on the extension and will just get an endless spinning wheel that never loads. This happens multiple times a day at random, making using the extension pointless.

Usually a very reliable VPN service (at least for the subscription) with some rare mishaps in streaming geoblocked live streams

Frequently I resume my session from suspend or hibernate on Windows, and the plugin popup window displays a spinner forever. Disabling and re-enabling the plugin does not help. Deeply unreliable.

It works... mostly... I am increasingly running into the issue of sites refusing to let me connect when I am using Proton VPN servers. This needs to be sorted.

Using the free version. Very reliable and fast to connect. Though the region is kinda random, still does the job, and allows to change to another random server every once in a while.

Functions as stated. However, they need to include this in the description: unless you have the paid plan, you cannot choose what country you want (even from the 10 free countries offered in the plan). The only option on the free plan is Quick Connect, which auto-connects you.

it's free and works well.

Funktioniert meist gut, manchmal undefinierbare Verbindungsabbrüche, sonst jedoch schnell und in Ordnung
