Can I have VPN on in one tab and off in another or another window (instance of Firefox) at the same time?

I want to use the new Firefox VPN feature for most browsing, however there are some sites which I am normally logged into, which do not allow access via VPN. Can I have it switched on in one window, whilst off in another? If so, how do I do this? If not, please can this be introduced at some time?

Hi. This does not sound like a question about the Common Voice project. I recommend that you ask about this on the Mozilla support site at support.mozilla.org.
