Anne van Kesteren on Mozilla Hacks about how they're enabling back the capabilities that were disabled in the wake of Spectre.

Though they do note it, the considerations that have went into both ensuring the safety of data and backward compatibility are awesome, and this is why I love the web. Yet I don't really have reason to use SharedArrayBuffers just yet so I have nothing to opt into yet :)

The sidenote on Project Fission is also neat to look into.
