Can't buy minecraft for pc/mac Java Edition

I can't see the page to buy it. https://minecraft.net/en-us/store/minecraft/?ref=h shows only "Loading store..."
https://minecraft.net/pl-pl/store/minecraft/?ref=h shows "Wczytywanie sklepu..." and stay in this screen constantly.
Firefox 59.0.2 (64-bit) on Fedora. Tried with normal browsing and private mode browsing.
