Why does it ask to access all_urls? Just press ctrl+shift+i and go to the inspector settings (press f1 here) and go to Available Toolbox Buttons and turn on full-page screenshot. No need for risking your privacy and data. Scary extensions be damned.
FireShot is straight-forward and user-friendly. It has a clean interface, making it easy to navigate. It does exactly what it says and has various features and options. Highly recommend.
