Add-ons • Dictionary switcher - buggy / partially functional

caa:addon/dictionary-switcher

Does the automatic function in this extension work for anyone?

Also, a question, does Pale Moon itself keep selected language per-site anywhere and where? Because my first impression is that it does. Or maybe it's a session thing? Somewhere in sessionstore.js? But, one thing is for sure, it's easy to have the selected dictionary as shown not actually being the one selected.

Edit: OK, maybe there's just one spellchecker.dictionary pref...it's like it started working better after resetting it...
