Autofill has stopped working, which it does from time to time.

I don't need to close the Chrome browser to correct the problem. Disabling, then enabling the 1Password Chrome extension, and logging back into 1Password, usually fixes the problem. However, it will fail again some seemingly arbitrary time later. I don't have a clue why this failure re-occurs, and I find the necessity to disable/enable and log in again annoying.
