give a nice way to do this.

Nota: This work as well with firefox too.

I'm not aware of a way to read command line params, but you can pass a URL to Chrome on the command line, and you can detect that URL being loaded. So a hack would be to call


  chrome.exe http://fakeurl.com/?all-the-data-you-need-to-pass

and have your extension redirect this URL to the new tab page and then act according to the data in the querystring. If you’re comfortable with the command line, you can also change Chrome’s behavior by launching it with command line flags. For example, the command below launches Chromium (the open-source version of Chrome) and tells it to cycle through the list of URLs in the specified text file, then exit:


/Applications/Chromium.app/Contents/MacOS/Chromium --visit-urls=/Users/cantrell/tmp/urls.txt
