I am looking for a crypto wallet that can connect to third-party websites.

That works on the Ethereum Mainnet. 

That will show my WALLET address and my TOKEN VALUE to third-party, connected websites.

But has a "firewall" feature that will not allow the third-party to withdraw my tokens.

I have used other wallets (i.e., TokenPocket) where my tokens were removed by questionable, connected websites (rep-eth.com).

I am seeking a cloud wallet where I can connect to third-party connected websites; and customize the permission, or has a built-in "firewall", where connected websites can VIEW my wallet address and VIEW my tokens, but CANNOT WITHDRAW my tokens.

Can Electrum wallet do this?  (or know of any other cloud wallet with this ability?)
