There are some addons/extensions that create vpn tunnels for Firefox browser. My question is: how to tunnel singular tab instead of ALL the browser?

Is there a way to do that? I tried with Firefox containers, but they have the same tunnel as the non-containered firefox.

so this is doable ONLY with mozilla vpn?

in theory no. In practice probably at present. You can always request your preferred VPN provider to create an addon that can tap into this functionality of firefox. Idk if they will do so though. Searching on addon site does show results for per container proxies, but I have no idea how dependable those addons are
