I have XP SP3 updated under the guise of "faux POS" (not all updates applied though)
Lately I find some cases - more and more often - of HTTPS sites that :
- under XP, won't open in Chrome (nor IE), i.e. using Windows own crypto API - but that -
- will open under Firefox - which has its own crypto stuff - even a very old version (3.5) works !
- under Seven, for compare, same sites do open even in Chrome (or, God forbid! IE).
An example page there exhibiting the phenomenon : https://www.aidanwoods.com/blog/faulty-login-pages/
Is it expected with fully updated XP SP
