Problems with chrome.webNavigation.getAllFrames

  • Hi, I hope this is the right place for my question.

    I'm working on adapting a Chrome extension for Vivaldi. There seems to be a problem with the chrome.webNavigation.getAllFrames method ( The callback is expected to receive a list of frames in a tab, but I'm getting null. Code to reproduce the problem (must be on a background page):

    chrome.tabs.query({active: true}, function (tabs) {'TABS', tabs);
        chrome.webNavigation.getAllFrames({tabId: tabs[0].id}, function (frames) {
  'FRAMES', frames); // logs "FRAMES null"

    Any clues/workarounds?
