Firefox (version 89.0.1) Spellcheck on Facebook
The last couple of days I've noticed that spellchecker is not working very well with Facebook comments. It seems to sometimes want to check only part of a word or do other strange things. I THINK it is only for the comments; it seems to be working ok when I write a post. Facebook is the only site where I've noticed an issue. Is this something that Facebook has done, or has an update to Firefox caused something to go wrong?
I have pulled up my about: config page for "spell" and am attaching a screenshot.
