Hi Lazza, I was a big fan of your script — loved being able to tinker with html in Evernote.
However I hadn't used it for a while and it doesn't seem to be working anymore. (Firefox, Mac 10.12.1). Essentially the script freezes the entire Evernote edit screen, can't type anywhere in it. In fact your </html> button doesn't even seem to appear there either (not that I could select it if it did, since I can't select anything below your toolbar).
I can only access your toolbar and even then it doesn't function very smoothly. I made sure I was updated to the latest version of your script.
Any ideas as to why it might not be working? Thanks very much
