Save WebP files to Original Format Easily

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. For comparison, 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 through a re-request to the server.)

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.

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)" - 9,060 => now 13,204 as of 19 Jan 2022 ( )
* "Don't "Accept" image/webp"- 4,217 => now 6,493 as of 19 Jan 2022 ( )

(Other inconvenient workarounds are described in the following thread:

Please, UX folks, take a look at this!

The suggestion is to build this in so an extension is not needed.

Super annoying behavior as it is now. Show of hands: Anyone who actually wants a .webp file when using Save as... on what seems to be a jpg or png? ANYONE??

And no, I do not want to use an extension to re-convert a webp back to what it should be in the first place, going through two unnecessary and potentially lossy conversions.

I'm on Windows 10, using the latest version of Firefox (Have used Firefox for a long time now) It's starting to get annoying when I want to share (Copy) a funny picture/meme to someone, only for it to paste as an non-viewable .webp in most applications (Messenger, Discord, Etc.), and I hit send so fast it's too late and I have to explain what is happening... I cannot believe this hasn't been fixed. From what I have read, Firefox can request webp instead of the image and it does so because it is compressed, saving load time/making it faster I guess? Now I understand that Chrome is able to bypass this/and you can save/copy the image as the default .jpged, .png, etc.

Because of this issue, I will now open the link to the image I want to share/save in Edge/Chrome and save/copy that way - might as well just use another browser in general if this is going to be the constant case.

I would also like to add that this change should also be implemented to the Clipboard. When I copy an Image it is pasted as .webp and this is causing similar issues with other applications
