£ character problem and FF

[moi1]

Hi all
Small problem with the £ symbol. I use the following code "&pound2.50" to represent the sum of £2.50.
no problem with ie, it renders: £2.50
however with FF it renders: &pound2.50,
if i leave a space &pound 2.50, it renders £ 2.50 with a space.
It is minor detail but very frustrating
Any idea ?????????
Thank you

And you're sure to add a ; at the end of your &pound ?
