I disabled webp in firefox and still had to get a secondary image converter extension to get around this format, I wish I could opt out forever.

Legitimately amazing compression for gifs, but isn't supported for shit outside of the browser it comes in, be it editing images or upload to older online galleries. Good luck to anyone who just renames the file format to png/jpeg, now you have no idea what's actually the correct format when you need it... I used to think that was a good idea, until I faced programs that would not run 'renamed' formats whatsoever.
