Notes

Has support, but was disabled across browsers in January 2018 due to Spectre & Meltdown vulnerabilities.
Enabled by default in Nightly, but not in Beta/Developer/Release.
Requires cross-origin isolation by having Cross-Origin-Embedder-Policy (COEP) and Cross-Origin-Opener-Policy (COOP) headers set. Mozilla Hacks article for context.
