Unfortunately, many programs are not compatible/interoperable with the WebP format. Users need a simple way to save images in traditional formats such as JPEG, PNG, and Animated GIF, which often is available from the server.

Background

Since Firefox added image/webp to its Accept headers, server farms often add WebP compression to JPEG, PNG, and Animated GIF files, changing the internal file format without modifying the file extension. That is transparent to users, but there is an issue: when using Save Image As..., Firefox saves the WebP format.

Sites also are starting to use the <picture> tag with a WebP <source> that overrides the traditional format in the <img> tag.

Firefox users often want the original image format to facilitate editing in programs that don't accept WebP, or for other reasons. Whatever the reason, because Firefox doesn't make it convenient, they often resort to using Chrome instead.

Parity with Chrome

In Google Chrome, if the file name has its original .jpg or .png extension, the browser saves in the original format. This appears to be done through a re-request to the server, which is similar to the workaround employed by some Firefox users of opening the Page Info dialog, Media panel, and using the Save As button (this request does not include image/webp in the Accept headers).

Other Evidence

I can tell this is a pain point based on Mozilla Support and r/Firefox posts, and because my WebP-related extensions have a surprisingly large number of users:

* "Save webP as PNG or JPEG (Converter)" - 14,757 users as of 6 March 2022 36,742 users as of Jan. 29, 2023 ( https://addons.mozilla.org/firefox/addon/save-webp-as-png-or-jpeg/ )
* "Don't "Accept" image/webp"- 7,092 users as of 6 March 2022 16,773 users as of Jan. 29, 2023 ( https://addons.mozilla.org/firefox/addon/dont-accept-webp/ )

So please, UX folks, take a look at this!

This most certainly doesn't work!! Just try GIPHY as an example.

Please implement this idea. Having *.webp images as downloads is unusable. I have to convert it somehow or I have to resort to making a screenshot. The annoying thing is, I see the URL of the image as *.jpg but I still download it as *.webp.

+1, webp is a great feature for viewing content, but should never be downloaded.

Why isn't this fixed yet? My older Macs can't migrate past MacOS 10.13 , and most of their supported apps can't deal with .webp formatted downloads.

Hey, make it a simple menu selection without having to dive into about.config and screw something else up while trying to force Firefox give me what I want.

Again, WHY isn't this fixed yet? Does Mozilla really want me revert to using an ancient (less secure) version of Firefox?
