I've hacked a quick mod of this (excellent) extension and put it on Github at http://bit.ly/8hbZQR -- code hacks (just changing the "max allowed version" to 3.999) at http://bit.ly/6tdX2Z . This is just a stopgap until the original author issues an update. No warranties whatever, use at your own risk.

As others have noted, this add-on allows you to keep message viewing in text mode, reducing security risks, and switch easily to HTML for messages whose origin you trust.
