To whom it may concern,
I'd like to make a suggestion with Mozilla VPN to add in Custom Block Filter Lists and Firewall Capabilities. Would be optimal for phone and windows / Linux / ios. For phone would be the biggest priority since it would increase the security. An app that has these same features is like Rethink, which provides everything free currently and open source. While VPN performance maybe not be as good as Mozilla, I think if these additional features are added would be really beneficial overall and be more competitive.
Thanks!
