Hi. It seems Mozilla extended the interface WorkerUtils in their implementation with the atob/btoa functions.
I find them quite useful in that context, and would also encourage adding escape, unescape, encodeURI, decodeURI, encodeURIComponent, decodeURIComponent and many of the other global functions in the DOM environment which don't have any specific bindings to the DOM itself or manipulate documents, as that was a concern due to globals that are internally used by the DOM in some browsers. Thank you.
