  3. Hit CTRL + P
  4. Select the print to PDF option.
  5. Click the Print button.
  6. Click the X button from the preparing dialog before the “Save print output as” prompt is displayed (or press the escape button before the “Save print output as” prompt is displayed).

Expected result

  • The print setup is properly displayed and the print job can be successfully initiated.

Actual result

  • Print preview error. Some printing functionality is not currently available.

The following error is displayed inside the browser console:
Uncaught (in promise) Exception { name: "NS_ERROR_NOT_AVAILABLE", message: "", result: 2147746065, filename: "chrome://global/content/elements/browser-custom-element.js", lineNumber: 1718, columnNumber: 0, data: null, stack: "print@chrome://global/content/elements/browser-custom-element.js:1718:31\nprintWindow@chrome://global/content/printUtils.js:297:16\nstartPrintWindow@chrome://global/content/printUtils.js:255:12\noncommand@chrome://browser/content/browser.xhtml:1:12\n", location: XPCWrappedNative_NoHelper } Browser-custom-element.js:1718

Regression Range

  • The issue seems to be reproducible on older builds as well (54.0a1)


  • This seems to affect only the tab where this issue was initially reproduced in.
  • This seems to be reproducible only on local pages.
  • Restarting Firefox or opening the print preview in that particular tab seems to fix this behavior.
  • [Suggested Severity] I think that S3 fits for this issue.
