Oddly, while Firefox nightly did disable my extensions after the update, Firefox stable has continued to leave them enabled. They're not working perfectly, but they're all enabled. xStyle, tampermonkey, etc are all working for me. The only problem is that they're now impossible to disable, because that entire UI no longer exists (I've got some extensions that do unconditional page modification, which I had to uninstall completely)
