Washington Post comment section

I'm stumped. For years I kept Firefox on my Windows machine (Win10, 64bit, 8gb ram) at some level around 80x (I forget the number). I even recently switched over to Edge until I got fed up with its complicated design. So when I went back to Firefox, I upgraded to the latest 147.0.3 (64-bit). At first everything seemed okay. But then I noticed I was having trouble posting comments on any Washington Post comment section OR the whole thing would freeze up or other oddities. ONLY there. Everything else runs fine. To add to the mystery, I walk upstairs to where I have a Mac (Sonoma, with 64gb ram) with Firefox 143.0.1. And I can post comments on the Washington Post, nothing freezes, everything works fine. So it can't be a problem on the Post's site itself. Back on the Windows machine I have tried various Firefox settings, changing the permissions from strict to standard, changing the performance settings, turning Add ons off and on one by one, running in Safe Mode. But no changes change the problem on the Post comment section. I'm at a loss to understand the difference. The Mac does have more Ram, but previous to my upgrade on the Windows machine, it was running the Post site just fine.
