Can't display google maps or msnmaps in firefox

[Oldman]

Hello all

Just after google maps went online I checked it out and was very 
impressed.  Ditto with msn maps or whatever it's called.  However I seem 
to have done something to cause it to stop working and I'll be darned if 
I can figure out what.  When displaying I get a gray box with some 
smaller gray boxes where the pins should be.

I have removed all extensions (but not plugins!) and this did not help.
    Interesting to note that if I fire up Mozilla, both sites work fine.

Anyone got an idea?
