@luciedigitalni LOL I contacted them back in 2023 about this.

"Thanks for reaching out. Fortunately the issue we had has now been resolved and we’ll need to update the on-page messaging – our payment provider had issues with Firefox and we were waiting for them to fix it up. Once again, thanks for flagging this with us and we’ll get this updated as soon as possible!"

Apparently ASAP wasn't *that* quickly 🤣
