I woke up today and the button for 1password is missing in Firefox. I have the latest version of 1password installed on my computer which is version 220.127.116.111. I’m running the latest version of Firefox (version 21.0). I’ve checked to see if the extension is enabled in Firefox. I've removed the extension from Firefox and reinstalled it. I’ve looked for the button under the customize menu of the toolbars in Firefox. Nothing I do works to get the 1password button back into Firefox. Please let me know what I need to do to get it back.
