Delete non-English dictionaries?

The spell-checking dictionaries on my computer now include: French (reform); French (classic); French (classic/reform); and French (modern). I have no clue how they got there, but spell-checking tries to default to French (reform). I don't see a way to delete them. Can anyone help?

Thanks, Ed LeRoy

Thanks for your reply, but frankly I don't know what a "Firefox button" is.

The languages tab in the Add-ons manager shows installed language packs.

What you want is to uninstall dictionaries and those appear on the Extensions tab (Tools > Add-ons > Extensions).

If you want to remove them all then simply uninstall the extension.


The 4 French dictionaries are installed via one extension in the dictionaries folder of the extension in the Firefox Profile Folder

  • fr-dicollecte@dictionaries.addons.mozilla.org

You can remove the files of the other dictionaries and only leave the two files for the modern version.

  • fr-modern.aff
  • fr-modern.dic

You can use this button to go to the Firefox profile folder:

  • Help > Troubleshooting Information > Profile Directory: Show Folder
