US English words are not underlined by the spellchecker
I have set the browser language to English UK. I have installed the English UK dictionary and set it as the default language. I was unable to remove the US dictionary through Firefox itself so I found the dictionary files and renamed [en_US.aff] to [en_US.aff.bak] which seems to have removed US English as a spellcheck option. UK English words are now considered correctly spelled yet US English words such as "customized" are also considered correctly spelled. Is there something I can do to ensure incorrectly spelled words are underlined or is this a bug?
It seems it is a bit of on and off my self as I use Canadian Dictionary. I seem to have to keep adding my stuff to the dictionary also after using a cleaner.
Copy/Paste about:preferences#general to Address Bar then Enter and make sure it is ticked. Is about all I know.
