Ok so built a new PC all setup used Firefox sync to get all my bookmarks over and things seemed to be working well. Then I noticed that spell checker doesn't work. No red lines, no options when I right click. I've also noticed that keyboard commands no longer work for copy and pasting. This is only on Firefox I tested on Chrome and Edge and had no issues. I've googled and nothing comes up that has fixed my issues. Check spelling as you type is ticked. I'm at a loss here had no issues before now.
