    This is the second time I have attempted to sign up for the free ProtonVPN

    Both times the same reason given for not working with my fire fox browser

    error setting authorization cookies…

    HUH!?

    Hey, if you already have a ProtonMail account, you can use it for ProtonVPN as well. Just simply log in to ProtonVPN website with your ProtonMail credentials and in the Dashboard tab you will be able to select a plan you wish to use.
