Forum d’assistance Firefox

Something changed a couple months ago where Firefox's spell check began only catching about half of my typos. Over the last 15 years I have become used to my browser providing spell checking services, looking for the little red lines to point out my mistakes, so now that this feature has stopped working reliably I am constantly submitting items with embarrassing typos, having to go back and edit almost every single post I make after the fact. Is there any way to get this working properly again? Thanks.

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
