I’m testing an extension of mine with Thunderbird 66 (current beta) and I can’t install the Spanish dictionary as I did before:
- Copy the dictionary file (webextension in this case) to my temporay profile folder, inside the extensions folder)
- Start TB in that profile
- Enable the extension via the popup that appears on start.
Expected behaviour: language spellchecker for the new language is correctly installed.
Current behaviour: the new language do not appear when composing and switching the language.
The dictionary installed is this: https://addons.mozilla.org/firefox/downloads/file/1670980/diccionario_de_espanolespana-2.4.xpi?src=dp-btn-primary
Is this supposed to happen?
