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.

Fine when it works, but since few days, regular infinite wheel and no connexion to any servers. Block all web traffic if I didn't deactivate the addon. (A kill button seems to be mandatory)

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

Up until recently, Proton VPN has been a GREAT option for me. It was the only free VPN I trusted and used and it worked great. However as of yesterday it stopped working. I've tried to uninstall it but it actually won't let me, and if I try to click on the icon/widget it is just a neverending spinning circle. Also, I keep getting a popup that says "Your networks seems to be blocking Proton. The extension can't bypass this. Try the desktop app instead"

This is very frustrating to especially since the mobile version keeps workings fine for now. I originally thought it might be a problem on my end, but apparently this has been an issue for many other people. Dropping my review so hopefully others know they aren't alone

good

it never loads anything and just displays a window with a spinning circle on it, and the circle keeps spinning till I crash out and delete the extension
