Save Full Page may not save full page, but will save as visible

FireFox 108.0.2 on Ubuntu 20.04LTS

I am attempting to Save Full Page on https://my.website-editor.net However, it will only save the same as Save Visible.

Attaching what Full Page saved.

Yes, this is a known problem on pages with interior scrolling. You'll probably notice the scrollbars within the screenshot. The Firefox screenshot feature does not have the ability to expand those regions to full height (or to put that another way, it doesn't have the ability to remove height restrictions on the page that force scrollbars on interior regions).

If you are a little bit familiar with HTML and CSS, then you can, on a case-by-case basis, use Firefox's Page Inspector (part of the Developer Tools, Ctrl+Shift+i) to work around this problem.

Start with the HTML tag at the upper left of the Inspector's tree display. Click that, and the Rules pane on the right should display the CSS. You can type height into the filter bar and turn off (uncheck the box in front of the rule) for any height or max-height rules that may be restricting the page height.

Repeat this check on the BODY element.

Unfortunately, some pages have various nested height-restricted elements, so those two might not be enough to resolve the issue.

It's possible there is an add-on which can do this automatically, but I haven't search for or tested any that claim to do it.

Thank you, but that seems silly that Firefox needs to read the contents of what it is presenting instead of just saving of what is showing.  File > Save Page As saves what it is showing.

Taking a screenshot is useful if you need to capture exactly what you see on screen. File > Save Page As saves the HTML code of the page to a folder on disk (and when you choose "Complete" it also saves images, scripts, style sheets, and various other bits and pieces of the page). The saved page isn't guaranteed to look the same as what you saw on screen, but it may be good enough in most cases.
