Firefox question

[R Kimber]

Recently (I can't say exactly when it started), all the Google adverts
on webpages I browse with Firefox (2.0.0.12 with 7.10) have acquired
horizontal and vertical scroll bars.  They do not have scroll bars in
Opera, nor in IE with Windows.

Is there a setting somewhere that will enable me to remove this
'feature', or does Firefox have a problem rendering Google ads?
