Rated 5 out of 5 stars

This is main reason I'm running firefox. I love this app, and just counted to 18462 .maff files on my laptop.
Of course it is totally unacceptable with software changes which makes such an essential add-on incompatible.
However, I'll continue to run firefox 56 as long as I'm here and haven't got another browser to work with the tremendously fantastic maff format. The so called MHTML or MHT is simply not an alternative. I don't like it, and there are no tools for handling it (only count free open source tools).
So from firefox version 57 firefox is dead as long as MAFF format is not supported.

Rated 5 out of 5 stars

The MAFF format is fantastic, and is the single reason I only run firefox. I consider it shameful that that the MAFF format no longer will be supported. This implies that I will stay at maximum firefox 56, which I'm running now for the rest of my life.

I save all interesting pages with MAFF, and there simply are no alternatives. The MHT/MHTML format is tremendously ugly and I haven't even seen any tools to handle that format (I only count open source free software, I do not bother about any proprietary).

MAFF is simple and elegant. The only acceptable web archive format I've seen.

I currently have 18589 .maff files on my laptop.
Now if either firefox or the maff-extension would have been proprietary software, then it it would be like the biggest insult you can do against a person, where a format suddenly would stop working. Fortunately I have downloaded all versions of maff and its source code as well as essential firefox versions in source code so I will manage.
