I finally downloaded an extension which I thought would auto-convert webp files on download, but even that extension's a pile of crap. Have to be on a page that's just the webp and click the right button and even then it downloads it to a sub-folder. Why is it so hard for people to just use a real file format and abandon webp as a failed experiment?
