Answer 1

The Developer Toolbar GCLI and Shift+F2 shortcut were removed in Firefox version 60. To take a screenshot in 60 or newer:

• press Ctrl+Shift+K to open the developer console (⌥ Option+⌘ Command+K on macOS)
• type :screenshot or :screenshot --fullpage

For Firefox versions < 60:

Press Shift+F2 or go to Tools > Web Developer > Developer Toolbar to open a command line. Write:

screenshot

and press Enter in order to take a screenshot.

To fully answer the question, you can even save the whole page, not only the visible part of it:

screenshot --fullpage

And to copy the screenshot to clipboard, use --clipboard option:

screenshot --clipboard --fullpage

Firefox 18 changes the way arguments are passed to commands, you have to add "--" before them.

You can find some documentation and the full list of commands here.

_{PS. The screenshots are saved into the downloads directory by default.}
