VistasHow can I manipulate the DOM using the chrome extension javascript
I want to create a chrome extension that is similar to the Toucan extension
For example I have this example.html without the extension
When I loaded the extension of Toucan it will manipulate the DOM of the website it will change some text content of the
tag. Unfortunately, I don't have any idea how to achieve this in javascript. (I have knowledge about content, background and popup in manifestation json.)

The general direction is to use a content script (defined in the extension manifest), that contains something like the following:
let paragraphs = Array.from(document.getElementsByTagName("p"));
Then, you can modify the first paragraph using
paragraphs[0].innerText = "new text";
