Firefox spellcheck doesn't work

[growse]

I'm running Ubuntu Gutsy, and for some reason the spellchecking in firefox doesn't work. I get the red underline thing, but the right-click options simply has a check box for "spell check this field" and a selection of languages - no suggestions or anything useful.

Any ideas why?

No, certainly not on windows.

I'm seeing this in textareas - not tried it in input boxes. I'll have a go without a profile tonight when I'm back at home.
