Support Us payment page makes it hard to pay with alternate browsers

I wanted to pay to use the Dark Reader extension because it's great! Unfortunately the payment option isn't available if viewing the site in a browser other than Chrome or Firefox (see screenshot). I was able to set my user agent to either of those two to get the payment option to appear.

I'm using Orion, but I also tried this in Safari on macOS, and doing it that way enabled me to pay with Apple Pay!

I suspect this is intended to keep people from paying for the extension and then being disappointed it doesn't work in their unsupported browser. But I wonder if instead, a better option would be a warning about unsupported browsers that appears for those users? I almost thought the payment option had been removed and the project wasn't accepting payments any longer.

Beginne damit, die Zahlungsseite „Support Us“ in Orion oder Safari zu reproduzieren, und vergleiche sie anschließend wie im Issue beschrieben mit Chrome oder Firefox. Als erledigt gilt die Aufgabe, wenn Besucher mit einem alternativen Browser die Einschränkung durch den nicht unterstützten Browser verstehen können und nicht zu der Annahme verleitet werden, dass Zahlungen nicht verfügbar sind.
