Hi,I want to append the same html elements to the current TAB document DOM.I want these html extended elements to live "forever", so I want to built them once, and append them on every page load by the content script.I was thinking to place the createElement commends at the background page.Then for every web page load, I want the content script to communicate with the background script, so it will append them to the current TAB document DOM.Is that good practice?My problem is that I donít know how to append html elements to the DOM from the background page.Can you please help?
