The Mozilla Hacks blog coverssome recent Firefox changes that will allow code from web sites to useshared memory and high-resolution timers in a (hopefully) safe manner."Together with others in the WHATWG community, we designed a set of headers that meet these requirements.The Cross-Origin-Opener-Policy header allows you to process-isolateyourself from attackers.
