I have image.webp.enabled set to false, I have image/webp;q=0 in my image.http.accept, but sadly some web sites still tried to shove this Google crap down my throat…
With this extension — not anymore!

WebP and other "open" formats and codecs by Google shouldn't exist in the first place.
Thank you for doing god's work with this extension!

Good initiative. Webp is a crap.

WEBP is the worst image container format ever invented. thank you for allowing us to block them.

100% :)

This works immediately. Thank you so much!

Thank you so much for this add-on. I could rant all day about how the webp and the gifv formats are a pain in the ass. But I am surprised not a single image application is adding support for these formats. Not counting MS Paint which seems to do webp. How did all these sites suddenly add support for these formats when no editors have? Until I can view these files in my Directory Opus and ACDSEE and can freely convert from one to another I don't need or want it.
Again! Well done on this addon

Does exactly what I wanted. Thanks!

Very useful, I use it daily on reddit.com

I hate webp. Imagine having to do extra step no one asked about before you can send image to your friend?
Well, this addon works well with reddit

with this extension websites like wikia and such that offer webp in addition to other extensions will finally send the proper file. no more webp pseudo drm to prevent/make it harder for users to download and use normal images.

Using this to download images from Reddit and other websites without that stupid webp format. Why you do this, Firefox?

Use this extension to prevent Firefox from saving New York Times images as webp. Works great, thank you.

It works, thank you.

Thank you i was tired for that file type.
Now google want to monopolize the images...
