Let me pay for Firefox

I realize it's far from a perfect solution to finance the creators of the only browser I consider usable today - but I subscribed to Mozilla's VPN service some two years ago, even though I virtually never use it, and mostly to help them make a bit of a buck through me. (And still, it is nice to have the option of geoblocking circumvention at the ready, although I'd wish for them to just support "ordinary" wireguard/wq-quick as a client option).

Hmm that might make them reallocate developers from the browser to the VPN ...

I could be wrong, but Firefox VPN is a relabeled Mullvard VPN, which probably has enough engineers to keep things going well. Plus, it's a VPN service, I imagine a small number of developers is all it takes to keep it up to date.

Subscription to their email forwarding service Relay is another possibility.

But then your payment goes to this Mullvad company although maybe Mozilla gets a small fee.
