FF not recognizing I installed a new dictionary
So my FF interface language is German but I do write a lot off stuff in English so I installed a bilingual dictionary. I have no clue how to enable it though. In "languages" the default German language is enabled. In "dictionaries" my new dict is enabled. When I right click underlined text in English it offers me either German OR English but not the bilingual dictionary. When I click "add dictionary" I get to the page where I found that bilingual dictionary in the first place. This is very confusing behavior.

I don't think you need this bilingual dictionary. You just need to install both English (US) and Deutsch (Deutschland) separate dictionaries from that page. You can use them both at the same time.
