Just upgraded one computer to Firefox v143.0.1 and now familysearch.org is very slow and will not load hints. v142.0.1 is still on my other computer and familysearch.org works normally. Within familysearch, I can click on a hint and a pane opens on the right. It normally populates within a second or two at most. With v143.0.1, it takes a minute to partially populate, then it goes no further. With v142.0.1 it works normally. I've disabled add-ons. Cleared cache. Deleted TEMP files. Restarted browser. Restarted computer. Nothing has worked. Previous upgrades over the years have not had this issue. Other browsers (Chrome, Vivaldi, Brave, Edge, SeaMonkey) do not have this issue. Attaching a picture of this page: https://www.familysearch.org/en/tree/person/details/G4QP-T3S A free familysearch account is required to see it--only an e-mail address is required. The right pane has been trying to load for over 4 hours at this point. Normally takes about 2 seconds.
