I installed this, tried it out.
Uninstalled it, reinstalled.
Multiple Firefox restarts between either.
I use it to switch the dictionary setting. It shows it has switched to another dictionary.
But spellcheck does not come along and sticks to the previous setting. I must still work my way through the context menu to switch dictionaries.
So far, all this has done for me is display a dictionary choice in my tool bar that bears at best incidental resemblance to the dictionary that the spellcheck will refer to.
