Thanks for the suggestion. I have thought about this approach, but 
there's a few things about handling HTML email that makes it tricky 
though: We want to this to happen without flashing a changing document 
at the user, we also want to ensure that bulk and junk messages that 
include bugged remote images and other resources do not lookup and/or 
load them when the HTML is parsed. Since this would need to be done as 
an out-of-process WebExtension, it's also all IPC, which is bad.

It may all may be possible, but it seems like just parsing and 
manipulating the markup before shipping it off to WebKit seems like it 
might be more robust and less work. I'll check with the WebKitGTK guys 
though.

Cheers,
//Mike
