I was greeted with this lovely message this morning when I launched Chrome. Did I miss a memo somewhere¹?

I understand their rationale: security privacy² blah blah blah. But to make it impossible to re-enable an extension I've installed, even if I know it's from a trustworthy source, is ridiculous.

Update 5 minutes later: Yup, seems like everybody knew about it but me. Guess I need to follow the "Chrome on Windows" tech scene a little more carefully.
