the second is that in Firefox the spell checker is now disabled by default until you manually activate it, when it was fine before. If this one isn't a bug is there any way you can switch it back to being on by default again please?
Not sure why this is, and I'm also not sure if there's any way I can control this.
Surprise, surprise. I found a setting in the editor that controls this behavior. It'll be fixed in the next update.
