I've been using the 1Password browser extension for ages without any problems.
For the last month or two however, it's become reluctant to fill in fields. When I click the 1Password icon, all the drop-down boxes display fine, but when I select a credit card or an identity, I only get the pop-up window with the details of the item - I don't know what its official name is, but the window that allows anchoring and editing. Form-fields don't get filled.
If I keep repeating the process, the info will finally fill the fields I'm trying to complete, but I often have to try 10 times before it works.
I've tried re-installing extension and restarting the browser. That initially seemed to help with credit card info, but not identities or bank account info, but it now problematic for all areas again.
