I see, that does seem to suggest that the issue is specific to Librewolf rather than Firefox. It's good to hear that the updates seem to have helped for now, but unfortunately, if the issue is random and difficult to reproduce, it may be difficult to pinpoint the underlying cause.
If this becomes a recurring problem in the future, I could see myself no longer using Librewolf and instead trying the Pale Moon browser to see if I get better results
