I want to change the text for the browserAction icon but I can’t get it to work.

content_script.js

browser.browserAction.setBadgeText({text: "Hello"});

Can someone help me out?

Thanks

You can not access the browserAction API from content scripts:

Here is a very simple way to accomplish what you need.

As you can see inside the code, you need to send a message (via browser.runtime.sendMessage) from your content script to your background page to access the browserAction API.
