Blockchain.info offers a
Chrome extension for it's "My wallet". This should eliminate the problem of potentially compromised javascript because the "full javascript bitcoin client is included in the browser extension" (quote from their site).
This sounds good and I get the feeling that using the Chrome extension adds another security layer. But I'm not sure how I can verify that the extension itself is not compromised. Has anyone reviewed the code for this? Is there a way to make sure the installed extension actually is safe?
