Office 365 Spell Check doesn't work in Mozilla Firefox. However it does work on Office 365 in Google Chrome. It also works on other websites on Firefox but not when writing emails on office365.

I have checked preferences (turned on as I type) and inspected elements (=true).

Still no red swiggle!

Have you tried it while Firefox is in Safe Mode?

Is this on an internet web page?

Did you look for a toolbar button in the editor to initiate a spell check? If it is a rich text editor then the website could probably have disabled the Firefox spell check and use its own instead.
