Chrome Bookmark Not Working

[BaseballGraphs]

Hello,
I've put together the following javascript that can be dragged and dropped to the favorites/bookmarks bar in Chrome (or any browser) and then when you click on it, it opens the links in the variable object:

javascript:(function(){ 
var obj={"link1":"http://google.com", "link2":"http://yahoo.com"};
for(key in obj){
var val=obj[key];
window.open(decodeURIComponent(val));
} 
})();

The function seems to ordinarily work when there are other tabs open in Chrome. However, when I am on the "New Tab" tab in Chrome ( I am running on 15.0.874.106 ), the function does not seem to work. It simply does not open a page?

Could it be that there is a problem with calling window.open from the "New Tab" tab?

Additionally, when I check the console, I am getting this output:

i18n-values: Missing value for "ntp4_intro_url"

Does anyone have any idea what might be wrong with my code or have any further information regarding this message I'm receiving in Chrome?

Thanks so much for your assistance!
