Comment 105 for bug 240133

Huh. Looks like Fennec won't be much of a threat for now, then. Perhaps if it saved as PDF and then emailed it, we may have a killer feature. His screenshot also exposes the lingering "unknown size" bug.

So Fennec will be able to save files as a type it can't even read? Sounds counter-intuitive. MHT is not perfect, but wider adoption will force the standard to make some improvements of its own.
