Have you had problems with other web sites too, or just those two?
Not that I can really help if you do, it's just that I also found Google was playing up for me about a day ago. Not just Google.com, but Google.com.au & Google.co.uk.
Female first is always stuffing up. It's very rare that a day goes by without FF giving me a heap of error messages.
All other sites seem to load fine for me though.
