how to load all of a 'bottomless' web page

[Robert Riches]

Is there a way to load _all_ of a 'bottomless' web page at once
without having to stand on the 'Page Down' key and watch the an
endless chain of yellow warning banners that a page is slowing
the browser down?

(The page is not really bottomless, but it looks that way for a
while.)

In particular, I'm looking to load a page similar to this one:

https://seekingalpha.com/author/jesse-felder/followers

I'm interested in other pages on that site have 40k to 50k
followers.

In Firefox ESR 78.4.1esr, I stood on the 'Page Down' key for
about 10 minutes on one page, and it would have taken over 180
pages to print the page, but the HTML (including the dynamically
loaded data) was not very many MB in size.

Based on watching the yellow warning banners, I'm guessing the
JavaScript code that fetches each next block has some algorithmic
inefficiencies, so that it is O(N^2) or worse.

Any suggestions?

Thanks.
