alert(web3.eth.accounts);

Hi, I am not sure I understood your question.

What application are you using, Mist or Firefox? Can you send a screenshot?

Thanks!

Hey i am working on a dApp project but i want to connect a transaction with a already deployed contract the problem is that everytime i am sending a transaction metamask pop up generates to submit or to reject transaction. I do not want to see that pop up as if the user want to send a transaction why will he install metamask etc. I want to develope a dApp that should be user friendly and there should not be any metamask pop up and all to submit or reject the transaction any help from your side will be appreciated thank you in advance.

Hi, from what you told me, it has little to do with Mist.

If you are developing a dapp in Firefox and a Metamask transaction window popped up, you are possibly calling some function like MyContract.method.call(…) instead of MyContract.method(…)

I'll close this issue, please make good use of web3.js documentation, according to the version you are using:
