>From recent discussion with a Firefox developer, I gather that browser vendors are generally trying to restore SharedArrayBuffer in wasm, at least; which is likely to result in it also being restored to JS. However, mitigating the Spectre weakness may involve constraining the use of SharedArrayBuffer; details remain unclear (and shall probably require developers from different browsers to reach a consensus on what's a good way to do this). He also noted that SharedArrayBuffer is a run-time preference in Firefox (about:config -> javascript.options.shared_memory); but it's a global option, not per-site, so enabling it may make expose you to Spectre exploits.
