How to Make a Firefox Screen Grab Without Any Tools

Firefox is capable of taking full-scale screenshots by default, even without plugins.

1. Once your page is fully loaded, right-click it and select "Take a screenshot". There’s a hotkey both on Windows and on Mac - Command(Ctrl) + Shift + S.

2. From there on, there are many options, such as clicking-and-dragging (to select an area), clicking an HTML element, or saving the visible area. You need to choose the option to "Save full page".

3. Afterwards, copy your Firefox screenshot to the clipboard or download it.

2. Click the app icon on your toolbar to use it.
