Has anyone used this? I got sick of the Australian English dictionary (it's really a spell checker) because a lot of words weren't in it and it occasionally gave corrections to words that were definitely spelled correctly. Now I've uninstalled the Australian version and got the British dictionary plug-in. Only this ones even worse. It's actually a US English dictionary mislabled as British, but also has many common words missing.
Does anyone know of a true English Dictionary plug-in for Firefox?
