Ask HN: Firefox VPN or Mullvad?

Like many I've been waiting for Mozilla to start providing useful services for which I can pay.

Firefox VPN is now available in my country but upon closer inspection I can see that they use Mullvad under-the-hood.

This is great! I'm a very happy Mullvad customer - but I'd like to know other peoples thoughts on using Mullvad through Firefox VPN - the price is the same - what cut do Mozilla take? is this detrimental to Mullvad?

I'm guessing Mullvad wouldn't have cut the deal if they weren't to benefit from it - so maybe I'm overthinking and should use this opportunity to put a percentage of my monthly $5 in mozilla's pocket as well
