VPN speed and connection quality are very good, however the VPN is finishing the subscription before the expiry date and not informing you why the premium subscription ended. İt is impossible to reach support center.

Bug: Inspite of plugin enabled on private windows in firefox settings, cannot change any plugin settings (it just shows a white blank popup) when clicked from toolbar button on a private window. Must fix this...

I'm free user, works fine, speeds ok on normal windows.
