Waterfox Facebook Glitch

Hello, while using ''Waterfox'', recently, while on Facebook, the ''time'' a post was made on any given page stopped being shown except for the most recent - newest - one. Per the attached screenshots, the newest post shows that it was put up 26 mins before I got the screenshot, the post prior to that one does not show how long it's been since it was made. This is '''only in Waterfox'''. Not a problem with Firefox, Chrome or Edge. Waterfox is my browser of choice for all social media, so this is particularly problematic. Thanks for any help in resolving this. ~ Bruce in Hawai'i
