Great extension.
BUT, at every FF start, I cannot access any pages without switching the extension off and on again. Then it works perfectly.
Having profiles and Netshield would be a great addition. :).

add kill switch function!!!

Loses connection after a few minutes

Unfortunately quite frequent reconnections, visible on the popup, which I quickly turned off.
The super-fast connection at browser start or after standby or hibernation should be emphasized positively in any case. Clearly better than the Windows app by a large margin.
If you need Killswitch, you have to use the app for the operating system, the browser extension does not have that.
Split tunneling also works very well: Now I don't always have to switch browsers for my online banking page, for example.

Would be nice to see what protocol is being used.
