The form allowing to pay using a bank-provided payment card (debit or credit, I never remember which one it is) seems to be broken again. It looks like it is endlessly loading, but will never actually load.

Disabling all content blockers (uBlock origin + uMatrix) does not help.

I am running Firefox ESR 102.5.0.

I remember several people reporting similar issues when GOG implemented support for Google Pay. Privacy extension blocking requests to Google services had the side effect of breaking the bank card payment form.

But this is something else this time, because even unblocking everything does not help.

--- No difference. Even after disabling Firefox built-in trackers blocker.

I get the same issue on my flatmate computer, who is using the latest version of Firefox.

I already spent one full year without the ability to buy anything on GOG, most probably due to some false-positive in their anti-fraud system ;)

I was also affected but could not remember exactly for how long it was and did not want to risk saying it was more than it was.

I don't think the browser itself is relevant then, since it works for me. Hopefully you've already opened a support ticket, since it can take weeks to get a response. And be sure to mention the troubleshooting you've already done, so as not to get those suggestions again.

I did not, and I do not plan to. GOG turned their support platform into an awful mess I no longer want to waste my time with.

I opened this thread so the issue can get some awareness, but this is as far as I am willing to go. In the meantime I will buy my games from other DRM-free stores ;)

Thanks for the invitation, because it actually made me find the cause of the issue!

While investigating further to prepare a detailed bug report, I noticed that an option of uMatrix stayed active despite disabling content filtering on the domain: HTTP referrer spoofing when requests come from third-party websites. By disabling this behaviour for the gog.com domain, everything is back on tracks. I got tricked because I thought whitelisting the domain would disable all of uMatrix behaviours, but I noticed the change by fully disabling the extension instead.

For other people using uMatrix, here is the rule to add to ensure the payment form works as expected: And to celebrate, I now have a couple games to buy ;)
