Save webP as PNG or JPEG (Converter) por jscher2000

This extension allows converting from WebP (or any other format) to PNG or JPEG. There also is a button to re-request the image masquerading as Internet Explorer 11 (you might need to click it a second time because Firefox likes to serve the cached iamge), and a button to send animated WebP images to ezgif.com for conversion to animated GIFs.

If you want to discourage sites from sending webP format images at all, especially if you are having trouble saving GIFv files, check out my other extension: Don't "Accept" image/webp.

Configuring the context menu item

These are the default actions, but you can switch them around to fit your needs (on the Options panel):

* Click "Save webP as..." to show format/quality buttons overlaid on the image
* Shift+click "Save webP as..." to save in PNG format
* Ctrl+click "Save webP as..." to save in JPEG format at 92% quality (on Mac, use Command+click)

Custom save folders

Extensions can only save under your Downloads folder, but you can set up date or site folders to help keep organized.

Troubleshooting

The button bar may not appear and images may not be saved if scripts are blocked from running in the page (for example, by the NoScript extension).

Notes

I regret having to use the "All sites" permission, but most images these days load from a different server, and that creates a cross-site access problem (canvas taint) that often blocks the extension from saving unless it has permission in advance. In a future release, I will try to offer a different approach that uses fewer privileges.
