I've been trying to figure out how to turn on the free VPN within the browser - (using this link: https://support.mozilla.org/en-US/kb/built-in-vpn?utm_source=www.firefox.com&utm_medium=referral&utm_campaign=whatsnew-150#w_turn-on-vpn-in-firefox)... ...but I can't find the VPN set up prompt or VPN icon anywhere in the tool bar. I've explored customizing the toolbar, even, to see if it's there, but it's not. Am I not eligible? (I am in the US and not in "enterprise" as far as I know) Please help me turn on this free feature. I'm not sure why it doesn't seem to be working on my Firefox (version 150.0 aarch64). Thanks!
