As a web-designer, I’ve always had to deal with extra work when i wanted to screenshot a webpage design. I used to do it manually, taking bit by bit the visible portion and then joining them together. It used to be a real headache! So i did a bit of googling and came across a really good firefox add-on.
It’s a firefox add-on called “Screengrab“. It can screenshot the visible portion, the entire page, or only a selection. The same can also be applied for adding it to the clipboard. I highly recommend you get it if you wanna make grabbing a screenshot of your webpage easier, be it for a client or for ThemeForest
