Review for Allow HTML Temp by Mark Jackson
Rated 4 out of 5 stars
Love this - I always read email in plain text if possible - but this advertised behavior doesn't work: "When switching to another message, it'll be shown automatically again in plain text or simple html mode (according to your settings" Original HTML is sticky, until I manually confirm Plain Text (which is already checked).
