Safari, Chrome etc. Extension 2.14.0 Broken - Edited title.

Thanks @cschombu for the TimeMachine suggestion! Since this issue doesn't seem to have a quick fix, I also went to retrieve 2.13 from TimeMachine history, unpacked it, locked out the updates URL, deleted the installed 2.14, and "loaded unpacked" 2.13. Now it works again. I'm surprised @1Password hasn't rolled 2.14 update back, but maybe this problem only plagues a subset of the users for some reason.

The 2.14 problem was also exhibiting a strange behavior where it would work fine when I started work in the morning (my MacBook wasn't off, just screen off, sleeping), but then an hour or two later the error would return. Perhaps some buffer filled? Or perhaps some other program/extension/usage pattern interacted with it so that it would lock up again. Perhaps this is why the bug got past testing/QA, maybe it wasn't immediately visible when the release tests were being executed.
