I have an older version of Office (and more importantly, Access) at work which doesn’t want to hear anything about .webp. When I need to make a document containing product pictures for a customer, .webp is a huge annoyance and time waste. Luckily the Firefox extension that bans .webp and forces .png or .jpg saves the day.

Transcoding and serving images as .webp as default is fine for saving BW and all that jazz, but when I click “Save image as” I should automagically end up on my disk with the original image format whatever that might be. But since that doesn’t seem to be a thing, I’ll happily find a way to force the server to serve the original all the time since for me BW is not a problem, but I don’t want to waste time converting every image before I can actually use it.
