Firefox 63, how to save screenshot of full webpage

[darkoshi]

Firefox used to let you save a screenshot of the full web-page via the Developer Toolbar:

(By the way, if you accidentally tried that from the toolbar shown in the Web Console instead of the Developer Toolbar, it didn't work, and showed an error, "SyntaxError: missing ; before statement".)

The Developer Toolbar has been removed in version 63 of Firefox:

So now you can save a screenshot from the Web Console; but you need to include a colon (:) in front of the command:
:screenshot --clipboard --fullpage

See:

In the Web Console settings, you can also select the "Take a screenshot of the entire page" option under "Available Toolbox buttons", to get a Web Console toolbar button for taking a screenshot. Using that button, rather than saving the screenshot to the clipboard, automatically saves a PNG image in the Downloads folder.

I told my partner about this, and she said "well, you know that there's an official screen shot UI in beta now, right?" Uhhh.... so I went to look, and sure enough. If you click on the "..." on the URL bar, there's now an official screen shot option. It does more than just the full page, too. Apparently they are also planning to add annotation support.

I had noticed the ... "Take a screenshot" option before, but had forgotten about it until Marahmarie mentioned it too in the comments.

I'm just glad there's an easy way to save a picture of the whole page, even when it scrolls, without needing to take multiple screenshots and splice them together. I used to have an add-on that saved a full page as a PDF file (and even let you omit sections that you didn't want included), but since Firefox Quantum, I haven't found a good replacement. The ones that are available now seem to use web services to create the PDF, which makes me concerned about the privacy of my data.
But the "full-page screenshot" is just as good to me, as a PDF.

The only, or main reason I even need this feature, is because my 401k website doesn't have an option for downloading or generating statements. The paper statements they send are few and far between. (I get the feeling they don't really want us to have a clear picture of how our accounts are doing, and they don't want us to know when they're losing money.) So I have to take screenshots, urggh.
