Just finished a Thunderbird extension. The only issue is the description doesn't show up in the Add-ons Manager when it's enabled in 7.0a1, but does when it's disabled. This may be their problem and not mine.

@extrapremium was complaining that my emails displayed white on grey for her. That's how I have my desktop theme set, but not something I'm supposed to be transmitting. After finding that Mozilla's stubbornness regarding body bgcolor and text attributes is an eight year old bug, I wrote an extension to strip them from outgoing emails if they match the user's defaults.

If interested: uncolorizer.xpi (no instructions: I assume you know what to do with the file; no UI: enable it or don't)

So, instead of being good and mowing the lawn in the 90° heat before the storm arrived, I had a geeky night of fun.
