WebmasterWorld FavIcon stopped showing in Firefox!?

Only WebmasterWorld, only Firefox (3.6.8)

I've not been on WebmasterWorld for a few days... My saved (ie. cached) tabs and bookmarks are showing the FavIcon in Firefox OK, but when I refresh, the FavIcon disappears (to the plain default FavIcon)!?

Only WebmasterWorld, only Firefox (3.6.8) - Other browsers (and other sites OK)!?

Has something happened - or is it me?!

The Content-Type of "/favicon.ico" is being sent as 'text/plain'. There is no TYPE attribute on the LINK element. This should be 'image/ico'.

Well, it's now working! But "/favicon.ico" is still being served with a 'text/plain' mime-type and the TYPE attribute is still missing from the LINK element - So I can't explain it!

(I have in the meantime cleared my browser cache and history, but I don't see why that would resolve this issue, unless it was corrupted somehow?!)

A few moderators have reported the same thing - but it's an inconsistent effect, not easy to diagnose.
