To use this method, an extension must request the "theme"permission in itsmanifest.json file.

Note that this always reset the theme back to the original default theme, even if the user selected a different theme before this extension's theme was applied (seebug 1415267).

Syntax

browser.theme.reset(  windowId     // integer)

Parameters

browser.theme.update(themes.night);browser.browserAction.onClicked.addListener(() => {  browser.theme.reset();});
