This problem appears on MacOS 10.13.3 but NOT Linux Mint 19.3 (Tricia).
1. Start here:
That page should load cleanly.
2. Now click on "Live Updates", which is the top entry in the middle column of that page, and as of 3 April 2022 11:20 AM EDT takes you to:
On MacOS, that page loads and is momentarily visible; then the page/tab it's loaded in goes blank. On Linux, that page loads as expected and remains visible.
The problem did not happen with Firefox 88.0.1/MacOS.
The problem does not happen with Firefox 98.0.2/Linux, i.e., it appears to be specific to MacOS.
The problem remains whether extensions are enable or disabled (one a time or all at once).
The problem remains after the cache has been flushed and pages have been reloaded.
The problem remains after Firefox has been (completely) shut down and (cleanly) restarted.
The problem does not happen with Chrome/Chromium on either MacOS or Linux.
The problem also happens on *some* other pages on CNN's site (but not all) and on *some* (but not all) pages of other sites but there doesn't seem to be a pattern that explains which URLs exhibit it and which don't. This suggests that it's not privacy settings or extensions or anything like that, because there's no reason for those to vary from page to page within any one site.
If I'm VERY fast on hitting the "X" that stops a page loading/rendering while in progress, and I get the timing just right, I can catch it before the page/tab goes blank. So it appears that Firefox is in fact fetching all the content and can render it, but then for some reason is blanking the page/tab once that's done.
The attached screenshot shows what the problematic page (from step 2 above) looks like on Linux. On MacOS it's blank, so I didn't include a screenshot of that.
