Can't open WP admin or site in Firefox

[Paul]

Ah, I didn't see this until now, but now that you mention it I've had this happen a few times too. FF doesn't always tell you it's crashed and it's only when it comes to shutting it down that you realise.

I know what you mean about problems in the last week. My broadband has been playing up big time and it's had me buying a new router, spending literally days running diagnosis software, and then as if by magic it's back running perfectly today with exactly the same set-up as it's always been. Very frustrating!
