"Following" timeline no longer chronological

[itsotter]

Hey, I'm using the extension in Firefox on desktop, and it's worked for months with no issues. As of a day or two ago, my timeline is showing posts out of chronological order—very annoying. I tried reinstalling the extension with no luck.

My settings all appear the same as ever, and visually it still looks like I'm on the "Following" timeline, it's just not working right. I hope I'm being dumb and there's an easy fix. Thanks for any help.
