How to set the badge text in a chrome extension from the content script?

It is possible to set the badge text from a background script. I was wondering if it was possible to do so from a content script.

Solution

  • No, it's not possible. You need to message a background page to do it for you.

    However, content scripts have some limitations. They cannot:

    Use chrome.* APIs, with the exception of:

    • extension ( getURL , inIncognitoContext , lastError , onRequest , sendRequest )
    • i18n
    • runtime ( connect , getManifest , getURL , id , onConnect , onMessage , sendMessage )
    • storage

    If you don't have a background page yet and are worried about possible performance impacts, look into Event pages (manifest V2) or Event pages (manifest V3).
