babylon translate tool

[Randolph Jones]

fc14, firefox 7.0.1
online translater toolbar 1.3.7.15 babylon french to english
works fine, but treats french words found in english dictionary as
english, ie defines them.
tribune in french is opinion piece, defines in english as lectern or
dias, not what is wated
how to stop this behavior, ie eliminate the english dictionary, 
and translate the french word to english equivalent? 
TIA
