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.

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.

I dont know why but im waiting signining in my account Proton about 25 min (( hope be better soon

as of March 20, 2023 I am encountering a few issues : a popup comes every 2 minutes to say that the VPN/proxy is connected, fairly annoying. Yet the most annoying is the fact that extension uses the Proton Webmail session instead of getting its own session (with restricted access!) just for the purpose of o VPN. If you logout the webmail it will log you out of the VPN extension as well. Plugin also lacks configurable exceptions. I will revise my review as updates are coming hopefully

Very Good and Very fast but it seems to disconnect randomly without any notification that it does so you dont know its not connected
