关闭后，保留Chrome扩展程序弹出窗口

Question

I'm developing a Chrome extension to have easy access to some documentation, basically it's a website in a popup.

It's working OK, but when I close the popup and I open it again, it relaunches the popup and I would like keep where the user was before closing it.

Any ideas?

So.. What I want to do is when the user open again the popup, show him the view he was watching.

setPopup is the essential code part you need to recognize.

 if(localStorage.Page && localStorage.Page != document.URL){
   //STORE CURRENT PAGE
    localStorage.Page = document.URL;
    //TRIM STRING
    var string = "chrome-extension://"+window.location.host+"/";
    String.prototype.ltrim = function() {
      return this.replace(string,"");
    }
    //SETPOPUP  OVERWRITES MANIFEST DATA
    chrome.browserAction.setPopup({
      tabId: null,          // Set the new popup for this tab.
      popup: localStorage.Page.ltrim()   // Open this html file within the popup.
    });

}else{
  localStorage.Page = document.URL;
}
