onInstalled chrome runtime debugging?

Question

chrome.runtime.onInstalled.addListener(function(){
    chrome.tabs.update(null, {url: ''});
    alert();
});

Above code doesn't work when I install my extension in developer mode. I want to update the active tab to be a blank tab once my extension installed in chrome web store.

That's an invalid URL, that's why it does not work.

You can't just "erase" the URL without navigating to what you supply as the new URL.

If you are trying to navigate to the New Tab page, it has a URL (that's normally hidden) chrome://newtab . If you want a blank page in terms of content, it's about:blank .
