I have downloaded French language for the rare occasion that I write in that language however the majority of the time I will write in English. When I start Firefox the default language is French but I would like the default language to be English and change to French when I write in that language. How do I do this?

What is the value of the spellchecker.dictionary pref on the about:config page?


Note that your System Details List shows that you have a user.js file in the profile folder to initialize some prefs on each start of Firefox.

The user.js file is only present if you or other software has created it, so normally it wouldn't be there. you can check its content with a plain text editor if you didn't create this file yourself.

The user.js file is read each time you start Firefox and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.
