Nightly has been my daily driver for years, with a couple of brief interludes. There’s the very occasional possibly serious breakage, but I haven’t noticed any compatibility troubles for a long time. (But I don’t use Facebook, and of Google I only ever use Maps.)
Actually, I suppose there are a couple of sites which Tracking Protection completely broke, but that’s not Nightly-specific.
