Wiggle.co.uk - "add to basket" breaks with HTTPS everywhere
I initially thought KeepassFox was the cause of this problem, but after getting some help in debugging it, it turns out that HTTPS everywhere is the cause of my problems: https://discussions.zoho.com/keefox/topic/wiggle-co-uk-unable-to-add-products-to-basket#71684000000270021
Is it the ruleset that is the cause of the problem?
My HTTPS Everywhere version is 3.3.1 - I am using Firefox 23.0.1
