First of all... You have done a fantastic job for making this app! Thanks a lot!
Well..I am facing some issues while running this app...
I executed ganache-cli to run the test blockchain network.
Then I executed node connect.js to deploy the Smart Contract and copied the Address to main.js file (line no. 4)
After that I ran node main.js and it gave me the address of a user.

So Who's address is this ??

When I open index.html it gives the following error in console:
Error: CONNECTION ERROR: Couldn't connect to node http://localhost:8545/
ReferenceError: curUser is not defined in index.html (But this should work as main.js is already imported)

Also I keep getting these Warnings:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://127.0.0.1:8545/. (Reason: CORS request did not succeed).
Source map error: TypeError: NetworkError when attempting to fetch resource. Resource URL: moz-extension://e8ea8fff-2a01-4c6d-b6c1-06e04dd84d38/contentscript.js Source Map URL: ../sourcemaps/contentscript.js.map
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at ‘http://127.0.0.1:8545/’. (Reason: Credential is not supported if the CORS header ‘Access-Control-Allow-Origin’ is ‘*’).

Thank You in Advance!
