Content Scripts

bugsnag-content-scripts.js

// In your extension's index.html you'll also need to include Bugsnag and disable auto-notification:
// <script src="bugsnag-2.min.js" data-apiKey="your-api-key" data-autoNotify="false">

// You can then add try/catch blocks in your content scripts, and pass any errors back up to your extension:

// Inside your content script
try {
  // Some code in your content scripts
} catch(e) {
  var exceptionObj = {stack: e.stack, message: e.message, name: e.name};
  chrome.runtime.sendMessage("extension-id", {type: "error", exception: exceptionObj});
}

// Then in your extension code you could listen for this message and notify Bugsnag:

// Inside your extension
chrome.runtime.onMessage.addListener(function (message) {
  if(message.type == "error") {
    Bugsnag.notifyException(message.exception);
  }
});
