Excellent add-on, thanks! I set the option to show the Save As dialogue each time and to save "Directly in my downloads folder", and for me it seems to remember the last save location so I don't have to go hunting for it each time. YMMV.

I haven't gotten the IE11 button to work yet, I still keep getting a .avif. But I may be misunderstanding something about that. Regardless, this thing is still great. Highly recommend if you are annoyed with getting .avif or .webp files when saving images.
