This problem appears on MacOS 10.13.3 but NOT Linux Mint 19.3 (Tricia).
Repeat-by:
1. Start here:
https://www.cnn.com/
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:
https://www.cnn.com/europe/live-news/ukraine-russia-putin-news-04-3-22/index.html
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.
Notes:
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.
