It sucks because I love Proton as a service and have been a paying customer for quite awhile, but this extension has always been completely broken on Firefox and it's derivatives. Everytime I first install it, the VPN works great. However, after I restart Firefox, it can never connect again and no website will load at all whenever it says "Connected". I need to reinstall the extension in order for it to work. It doesn't matter what fork I'm on, it doesn't matter what PC I'm on, and this has been happening for years. Works great on Vivaldi which you'd expect, given the extension is pre-loaded in the browser...but cmon I'm a Firefox guy and I'd like for this to work so I can use the VPN I'm paying for on my browser of choice. Until then, I'm not paying extra for it.

if you disconnect it does nothing, you stay online, and you will just be surfing with no protection until you notice it isn't connected anymore.

Junk VPN and waste of time.

даже не запускается расширение!

Mainly I use this extension on Chrome-based browsers, which gets labelled as a different "device"(?) This is very easy to use on both browser platforms. It was surprisingly difficult for me even find how to rate a FF extension on Mozilla! But it's definitely worthwhile for someone who uses Firefox only occasionally

IPv6 is leaking when split tunneling is enabled. (include mode)

So there really is a widespread issue between Proton VPN and Firefox. I’m frustrated, I’m a premium subscriber on an annual plan, and I still can’t use the service in the browser that’s officially supported via the extension. We need an ETA! It’s been almost two months with no updates.

Aww yeahhh

Works great until my laptop goes to sleep. Then it disconnects, and for some reason prevents Firefox from connecting to the internet at all. And since Firefox isn't connected to the internet, the extension doesn't load properly, so I can't even turn it off! I have disable the add-on to get Firefox to work, at which point I can reenable it and reconnect the proxy.

Idk why it has low rating, it does what it's supposed to do and works fine. If you want upgrade you need to pay tho

Works perfectly

I find Proton's overall service quality, server speeds, and desktop application very successful; it's a genuinely good service. However, the browser extension (Zen, Vivaldi, etc.) unfortunately does not work properly on this computer.
The moment I click connect, the extension turns "green" (connected) within milliseconds, but no pages load and it throws a "Connection Timed Out" error. I have checked all network settings and DNS configurations on my system. While other competing VPN extensions work flawlessly on the exact same system, only Proton's extension gets stuck in this fake connection loop and fails to route traffic properly at the OS layer. This extension urgently needs an update to match the quality of the overall service. Until the extension is fixed, my rating is 1 star.
