For best results with animated images, try using the "IE 11" button. That will re-request the original URL for the image as a dumb browser incompatible with WebP. That doesn't work on all sites, but it's worth a try.

If you are noticing that a specific site doesn't work with the "IE 11" button, could you share a link? You can send it by email jscher2000@outlook.com or create an issue at https://github.com/jscher2000/Save-webP-as-extension/issues. Thanks.

Hi Peter, you can contact me for support through the Issues page at https://github.com/jscher2000/Save-webP-as-extension/issues or by email at jscher2000@outlook.com. Hopefully we can get it working again.

Thank you for your comments. If you want to propose changes to the Options page, or other aspects of the extension, please submit them to me on the Issues page at https://github.com/jscher2000/Save-webP-as-extension/issues or by email at jscher2000@outlook.com and I'll take a look.

Thank you for your feedback. For animated webP, the "IE11" button works the best for saving in an animated GIF format, assuming the server offers one, but isn't perfect. For WebM, I could try linking to an online conversion service but I'm not aware of one.

The Save As dialog takes advantage of Firefox's built-in behavior to remember your last used folder per website. I actually don't know whether I can override that in the add-on; I'll need to look into it.

Hi, do the save options help? You can have Firefox prompt you each time if you need to use a range of folders. As you can see I was planning to let you pick any folder under Downloads (add-ons can't auto-save outside of your default "Save files to:" folder) but haven't finished that yet. https://addons.mozilla.org/user-media/previews/full/265/265268.png

Sorry to hear about that. This add-on doesn't have a feature to delete saved images, but the images are handled as downloads and Firefox itself has a feature to delete downloaded files. The way that works is to right-click an item on the download history list and click Delete -- if multiple downloads are selected, all of the files for the selected items will be deleted. If the files weren't deleted through that feature, perhaps they are in the Windows Recycle Bin (if you run windows) or your system's equivalent. If not, you could try "unerase" software like https://www.ccleaner.com/recuva

Hi rotie, could you start a thread on https://github.com/jscher2000/Save-webP-as-extension/issues/ and give an example of a page where it doesn't work, or email me at jscher2000@outlook.com

**Update** I noticed this can happen in a framed page. Try using either right-click > Open Image in New Tab (use the stand-alone image viewer), or right-click > This Frame > Open Frame in New Tab to work around this issue for now. Hopefully I can figure out the issue.
