Unable to highlight for copying text & half the article doesn't load


A screenshot won't work for this, and it only happens on SA, not other websites I have opened in other tabs.

- I can't highlight and copy text.

- The article, which previously (a few minutes prior) loaded fine, now won't even fully load itself.  It is just blank screen until I get to the comments section.

- Firefox v86.00 for Windows 10

- Windows 10

- Java Script allowed (though this shouldn't matter, because the webpage with the article in question was working just fine a few minutes prior)

- Webpage:  https://seekingalpha.com/article/4410149-how-to-invest-in-hydrogen-part-2-top-picks

- Misc Note:  This has repeatedly happened to various articles over the past few weeks . . . . just FYI.
