After a short time scrolling on Facebook, screen will jump up or down my newsfeed
While scrolling down my newsfeed on Facebook, the screen will start jumping up and down along my feed. It works fine for a few minutes, but after that, it becomes unreliable and skips along. It makes it difficult to find where I was and makes it hard to scroll to the next item on the page. This seems to specifically be a problem with Facebook.

This is a specific Facebook-Firefox problem that seems related to a script change on Facebook related to content autoloading. Testers say it affects Firefox as far back as version 78. However, I have not been able to trigger it myself.
There is a bug on file with Mozilla, but I'm not sure whether the specific interaction has been identified so it can be fixed by either Facebook or Mozilla.
only happens on FF on FB- does not happen on Chrome
