Never got it to actually function. It goes through the motions -- scrolls the screen, makes a "shutter click" sound, but I never found any images, nor anything on the clipboard.
Also, reported for excessive permissions.

不错

sehr schlecht !

Does what it says, but when you have a pop up to take a closer look at the item and decide to save, it goes back to the default view and that doesn't work for me on websites like Archiexpo etc. too bad it worked okay, but nothing like awesome screenshot which no longer works.

It's long time I use it and I haven't been able to find a better/more handy one.
Six Stars!!! Thank you. :-)
