I'm not having any luck recovering the 1Password add-on for Firefox. I know that this has come up several times in the forums. I've read all of the responses and tried all of the steps suggested. I unchecked and rechecked the browser extension boxes in 1Password preferences. I reinstalled 1Password and once more followed the steps in 1PW preferences. I even tried disabling all of the browsers and then enabling them again. I tried all of this for both Firefox 4 and 3 (including 3.6 and 3.5.9). I'm at a complete loss as to what else to do.
Thanks in advance for your help!
