I want to add some elements and a small script to my new tab, without modifying anything else about the default page. I've looked everywhere, and I can't find a way to do this anywhere. I've tried content scripts, instant failure, executeScript, instant failure as well, and everywhere I look I find the same answer "Chrome doesn't allow this for security reasons". However, this is for the purpose of a personal extension, and I'm absolutely certain there is a way to modify the chrome browser itself to allow this by disabling that feature alltogether, possibly through a flag? So how can I do this?
