In here it's said we need to run below command line to let Metamask connect to geth:
geth --rpc --rpccorsdomain="chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn"
I'm running a private blockchain and when I run the above command line it tries to synchronise and it takes a very long time. It looks like it is connecting to a real blockchain network which I don't need right now.
Obviously, I need Metamask, as I want to write my own user interface that can interact with my private blockchain (or smart contract).
Question: Do I need to run the above (or any other) command line to let Metamask connect to geth when I'm using a private blockchain?
