Why does the add-on require me to allow it to run in private windows? What if I don't want to use it in private windows anyway? Does it just want to collect some data when I use a private window, which exists to prevent tracking to a certain level? Kinda ironic for a VPN/Proxy Service...

Edit because of the Developer response: "You may choose to enable or disable this permission when installing the add-on, as well as in the Menu > Extensions section." No, I can't and that's the issue: If I do this the extension won't work any more, if I click on it it just tells me that the "Permission to run in private windows is required by Firefox for the extension to work." even in regular, non private/incognito windows.
