Why is Firefox refusing to display Instagram videos?

Windows 7 Home Firefox 115.12.0esr (64-bit) Some Instagram videos play, most don't. E.g. https://www.instagram.com/reel/C8FM6cbOG7v/?mc_cid=e24e48195f

For a fraction of a second, the video shows what appears to be the initial display frame, then goes black. Audio plays. Displays OK on Chrome and Edge.

I've explored the following: Autoplay is allowed Turn off tracking protection Clear cache Clear cookies Digital Rights Management (DRM) is allowed Running in trouble shoot mode, i.e. no extensions Popups not blocked I do not have file user.js I tried hiding prefs.js. Hardware acceleration either on or off: no display

Is there a setting that tells Firefox to report why it makes its choices?

Firefox is my preferred browser, and I have a very comprehensive list of bookmarks with folders and subfolders. Recently, whenever I add a bookmark through 'Manage Bookmarks' to access this list more easily than 'bookmark this page' > 'edit bookmark' & > 'Choose', it works the first time only; after that if I add another the second will not appear. If I close the 'manage bookmarks' window & reopen it & scroll to where I was before (a time consuming exercise), I can see that it did add the bookmark— for some reason it does not show when I do. This happens if the window is idle more than a few moments. Ideas how to fix?
