In a future release, I will try to offer a different approach that uses fewer privileges.WebP is an image format developed by Google which is comparatively smaller in size than JPEG and PNG formats and gives better quality images in small size. 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. 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). * Ctrl+click 'Save webP as.' to save in JPEG format at 92% quality (on Mac, use Command+click)Įxtensions can only save under your Downloads folder, but you can set up date or site folders to help keep organized. * Shift+click 'Save webP as.' to save in PNG format * Click 'Save webP as.' to show format/quality buttons overlaid on the image These are the default actions, but you can switch them around to fit your needs (on the Options panel): 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. 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 for conversion to animated GIFs. This extension allows converting from WebP (or any other format) to PNG or JPEG.
