How to make Cent open new tab on start?

[rey]

once again i find Chromium engine as veeeeery poor 
no way to customize tabs colors and no extentions..  now simple task to open new additional tab on start-up keeping others not loaded, and again no easy way(judging by no answers). yet it seems to be no extention for this(real disgrase!), and only thing Maybe could help is javascript that i found:

Code:

chrome.windows.onCreated.addListener(function() {
chrome.windows.getAll(function(windows) {
 if(windows.length == 1) {
  chrome.tabs.create({})
} }) })`

but again - hell knows how to make Chrome execute script on start.
