I'm using the latest Firefox (16.0.2) and the latest browser extension (3.9.9). I'm having a problem whereby if I'm viewing a website (e.g. Quidco.com) and I click on a link to visit another site to take advantage of a bargain, the 1Password button which normally sits on my Navigation Toolbar disappears; this obviously means I cannot login to the site, instead I have to open my Mac App Store download of 1Password and fetch my login credentials from there.
Is this a known bug?
Thanks for your help.
