Remove limits on Full Page Screenshot functionality

[Franpa]

Is there any way to make the Save Full Page aspect of Firefox's Screenshot functionality perform consistently and take screenshots of full pages? https://imgur.com/a/saBvPrA

Its behaviour changes depending on the website. For example:
Full screenshot: https://imgur.com/a/l8AvqOI
Partial screenshot: https://imgur.com/a/em2PtpU

I've tried various add-ons for this and they all have identical behaviour.

I think there was an extension that would expand scrolling sections within pages automatically, but the Firefox Screenshot extension doesn't have that feature, it only scrolls if there is a scrollbar on the body.

I think you would need to apply a style hack to the page so it can be more easily captured. Is there an example page to experiment on?

Firefox already can take partial=window or full of page, no flaws here. If you have issues with dynamically loaded pages then you to scroll until the end.

Maybe try to zoom out the page before taking the screenshot.

Can you post a link to a page where you experience this that doesn't require a login ?

Pretty sure Hotmail isn't unloading assets that aren't in view, unlike say the homepage of Imgur which does dynamically unload content as it is scrolled out of view (and is visible in the full page capture, out-of-view image thumbnails will be blank colour slabs).

This is not a difficult problem to demonstrate. If you click the yellow button on the following tester page to switch from a scrollable page to a scrollable region of a fixed-height page, you can't get the "full page" in the screenshot:

And even with scrollable, on that page, because of its length & limitations to the screenshot tool, it is still truncated.
(And that page is relatively short.)
