Firefox browser extention wonky
I've been using 1Password since its inception, and this is an issue I've never come across before. The extension icon is still in the menubar, but when I click on it the information shield that comes up is blank. I can still use command\ to fill in username and password in most cases, but I can't get the normal pulldown to work. I've restarted, checked for updates and reinstalled the extension twice. Still no luck. Any suggestions much appreciated.
I'm on a MacBook Pro running 10.8.4 and Firefox 23.0.1
