-/*** 2300: SERVICE WORKERS ***/
+/*** 2300: WEB WORKERS [SETUP]
+     A worker is a JS "background task" running in a global context, i.e it is different from
+     the current window. Workers can spawn new workers (must be the same origin & scheme),
+     including service and shared workers. Shared workers can be utilized by multiple scripts
+     and communicate between browsing contexts (windows/tabs/iframes) and can even control your
+     cache. Push and web notifications require service workers, which in turn require workers.
+
+     [WARNING] Disabling workers *will* break sites (eg Google Street View, Twitter).
+     It is recommended that you use a separate profile for these sorts of sites.
