Thanks Gez. I would have missed several GOG giveaways had it not been for you flagging them up (and, yes, I do get emails from them but I have a bad habit of not checking that account frequently enough).
Tangentially related, I have noticed that, in firefox, the giveaway function has not been working recently:
For some reason, it never gets past those three dots just flashing away. It works fine on Chrome. I've tried disabling NoScript, uBlock, Privacy Badger etc. but firefox still refuses to allow the site to work. Anyone else experiencing similar?
