I created my Mozilla account specifically to share how disappointed I am with this add-on. It was once a great free add-on but now it is horrible.
Originally there were numerous connections you could make per region, then a few months ago they restricted it to just being able to select 1 of 30 regions, a couple days ago they restricted it to only 4 or 5 regions.
Today, I only see 3 regions and the add-on fails to connect to any of them. What happened?
If I'm going to pay for a VPN, it won't be this one. To go from hundreds of possible connections to 3 that don't work in a year's time is unacceptable.
