捕获'open link from external link-call‘事件

Question

我正在搜索一个事件，当外部桌面软件，如Outlook，Thunderbird，Messenger App等想要默认浏览器(firefox)打开一个新链接时触发。如果firefox之前被关闭，我可以使用一个解决方案来捕捉这个事件：

// catch page when triggered by link and browser was closed
chrome.runtime.onStartup.addListener(function () {
  // search for initial tab
  chrome.tabs.query({
    active: true,
    currentWindow: true,
  }, function (tabs) {
    var initialTab = tabs[0];
    // catch open of files and links when browser was closed
    if (initialTab.url != 'chrome://newtab/') {
      handleNewUrlRequest(initialTab.id,initialTab.url);
    }
  });
});

但是，当firefox已经在运行时，如何捕捉外部链接的打开呢？

感谢您的帮助和问候！

感谢@wOxxOm，我以这样的方式做到了：

// catch page when triggered by link and browser is already open (firefox) step 1
var lastRequest = null;

chrome.webNavigation.onCommitted.addListener(function (details) {
  if(details.url == 'about:blank' &&  details.frameId == 0 && details.parentFrameId == -1 && details.transitionType == 'link') {
    lastRequest = details;
  }
});

// catch page when triggered by link and browser is already open (firefox) step 2
chrome.webNavigation.onBeforeNavigate.addListener(function (details) {
  if(lastRequest && details.frameId == 0 && details.parentFrameId == -1 && details.tabId == lastRequest.tabId && details.windowId == lastRequest.windowId) {
    console.log('New Request detected: open new Link in Firefox when Firefox is already open');
    lastRequest = null;
  }
});
