I'm new to the Redux world, so I was following the Todo List example of the redux.js.org , I tested the code and it works just fine with the redux store having only the reducer as its parameter :



import React from "react";
import render from "react-dom";
import Provider from "react-redux";
import createStore from "redux";
import rootReducer from "./reducers";
import App from "./components/App";

const store = createStore(rootReducer);

render(
<Provider store=store>
<App />
</Provider>,
document.getElementById("root")
);


as soon as introduce window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__() as a second parameter to the store in order to be able to use the redux devtools I get this error :
error
I don't see where I went wrong, I hope you guys could help me figure it out.

          This is a bug in the Firefox add-on that has been fixed in version 2.15.4 as explained in this issue, so if you upgrade the add-on it should work as expected.
