this is fantastic

лично у меня не работает

Works fine. I'd recommend you right click on the icon, select "manage extension" and then the "options" tab, and check the box that says "hide hovering buttons". They were constantly getting in the way of interface elements I was trying to click.

good concept. add on doesn't actually work, at all.

Работает. Уже хорошо. )

Was working great yesterday, but seems there was an update today and it doesn't work now. The picture just shows up as blank now.

Works perfectly when I have tested it. Like Instagram. I tried the other Pinterest add-on "Save image on Right Click" which did not work in any meaningful way.

Slowed down the browser immensely.

On some sites it works better on some less. One very annoying issue is that it overlays the UI on youtube's thumbnails so that I can't use it (e.g. use the watch later function within the thumbnail)
