(I worked on screenshots)
Sure, but firefox has knowledge about the geometry of the dom, so you just click on the element you want and it intelligently sizes the shot for you.
Also, before it was screenshots it was Page Shot, and it allowed full text search of the text in your screenshots. Management killed that before launch for some reason.
Finally,d you’ve always been able to save the shot locally instead of uploading it to the server, and you’ll be happy, because the server is going away later this year and you’ll only be able to save them locally.
You may know how to use your os screenshot tool, but we got a lot of positive feedback from non power users who don’t. Right-click->Take screenshot is a lot more discoverable than command-shift-4.
It mystifies me why people hate features they don’t use. So you don’t like it — so what? Other people do. You are the one generating the hate for no reason.
