Gets the text color for the browser action's badge.

Note: This API is available in Manifest V3 or higher.

In Firefox, unless the badge text color is explicitly set using action.setBadgeTextColor(), the badge text color is automatically set to black or white so as to maximize contrast with the specified badge background color. For example, if you set the badge background color to white, the default badge text color is set to black, and vice versa.

Other browsers always use a white text color.

This is an asynchronous function that returns a Promise.


  details // object




tabId Optional

integer. Specifies the tab to get the badge text color from.

windowId Optional

integer. Specifies the window from which to get the badge text color.

  • If windowId and tabId are both supplied, the function fails.
  • If windowId and tabId are both omitted, the global badge text color is returned.

Return value

A Promise that will be fulfilled with the retrieved color as a action.ColorArray.


Log the badge's text color:

function onGot(color) {

function onFailure(error) {

browser.action.getBadgeTextColor({}).then(onGot, onFailure);
