I decided to try Webp to as a format for images in order to have images more compressed than jpg, however I’m struggling with using the available polyfils for browsers other than Chrome and Opera (where they are working perfectly), namely Firefox.
I have tried placing both of these polyfills in my compatibility folder:
First one seems seriously outdated (last update was in 2013) and uses both a js and swf files.
Second one is recent and just a js file.
However both of them are not rendering my webp images in Firefox.
