Rated 5 out of 5 stars
This addon does SOMETHING at all.
try websites that use 'alt' attribute popup, not 'title' attribute.
you can't see popup text over picture without this addon (in firefox).
although it displays naturally in IE.
most websites doesn't use 'alt' attribute nowadays.
nevertheless, this addon can be very useful sometimes.
I think this is one of essential addon, if you don't want miss something that others can't miss.
