I read and write on the web in two different languages and it would be really handy to teach firefox to use this spellcheck dictionary for that and that website while the default one would be english.

Is anything like that possible?

Toggles between the installed dictionaries automatically or manually and displays the currently selected dictionary in the status bar.
