Errors while executing browserify-fs

I'm seeing below error while accessing - https://tonicdev.com/npm/browserify-fs on FF/Chrome on windows 7

ReferenceError: self is not defined
message: "self is not defined"
stack (getter): function()
stack (setter): function()
ReferenceError Prototype

...

While executing it on command line:
D:>node test-bfs.js
D:\node_modules\browserify-fs\node_modules\level-js\node_modules\idb-wrapper\idb
store.js:129
var env = typeof window == 'object' ? window : self;
^

Start with the failing environment selection in idbstore.js around line 129, then trace how browserify-fs/index.js reaches it through level-js. Reproduce the reported browser and command-line cases on Windows if possible. Done means browserify-fs no longer raises the reported “self is not defined” error in those environments.
