I am new to Chrome extension. I have a question about how to make the extension to open a “Help” page automatically after installation. Currently, I am able to check whether the extension is running the first time or not by saving a value into localStorage. But this checking is only carried out when using click the icon on the tool bar. Just wondering if there is a way that likes FF extension which uses the javascript in to open a help page after the installation. Thanks.

Edit:
Thanks for the answer from davgothic. I have solved this problem.
I have another question about the popup. My extension checks the url of current tab,



if OK(url){

    //open a tab and do something

}

else{

    //display popup

}

Is it possible to show the popup in this way?

    UPDATE: This method is no longer recommended. Please see Nuhil’s more recent answer below.

    I believe what you need to do is put something like this into a script in the <head> section of your extension’s background page, e.g. background.html

    function install_notice() {
    if (localStorage.getItem('install_time'))
        return;

    var now = new Date().getTime();
    localStorage.setItem('install_time', now);
    chrome.tabs.create({url: "installed.html"});
}
install_notice();
