UPDATE: Firefox warns about this add on's website!: http://www.northghost.com

Downloaded this recently. opened it, chose my options and logged in. All okay. Tried it again a few moments later only to be greeted with a blank page. Disabled it and closed down firefox only to log into my gmail accounts to find the security notification which was due to being still logged into Touch VPN? Re-enabled TVPN only to find the page blank. This on Private browsing page also? Repeated options stated with same result -blank page?! A few days later same issue?
