I've been having some strange issues recently with the 1Password extension. I will go to a site that I know that I have a saved login for. I press CTRL+\ to auto-fill my credentials. Sometimes nothing happens at all - no autofill, no helper popup with suggestions. Sometimes it works fine. Sometimes it pops up the helper but there is no site listed, just Search, Favorites, Tags, Password Generator, etc.
Once in a while I can refresh the page and that will fix it and auto-fill or the popup will appear with suggestions once I press the shortcut keys. If that doesn't work, then I can right click the page, click 1Password from the context menu, and then it will show the logins for the site I'm on, which I can then click the one I want to use and it will auto-fill for me. I've seen the same behavior in both Firefox and Chrome. The Firefox extension was just installed today, so it doesn't seem to be a version issue.
