Stipefoarum foar Firefox

Hello!

I am multilingual and write in multiple different languages, and the red markings from spellcheck underneath non-English sentences get annoying when they are so frequent. I understand that I can install multiple dictionaries, but that does not allow me to use more than one language's spellcheck at a time.

Is it possible to activate 2+ language dictionaries in Firefox?

Thanks for the help, Sylvan
