WYSWIG Editor Stopped Working in NOVA

[RobNH]

I'm running the latest version of XenForo and the NOVA style on all three of my websites. One of the sites, the WYSIWIG editor buttons are suddenly grayed out and non-functioning in the latest version of Mozilla Firefox. It happens on only one of the forum sites but not the other. I've cleared browser cache - and everything works fine in Microsoft Edge and Google Chrome. I haven't changed any of the settings or options so I'm not sure what could be causing this. Suggestions?

The little [ ] two buttons to the left of the preview button activates BBCode mode, you need to disable that.

Ugh...I feel like such an idiot. Thanks Russ.

No worries, I've looked over things far simpler than that!
