Hello: I am developing a test with selenium 3.11.0 + geckodriver 0.19.1 + firefox 59.0.2 to get the HAR file when loading a page. I got always an error, and no HAR file when using the latest version of Firefox. I could not find any error in the test configuration, and the logs showed always an error in the javascript har-builder.js, which is internal to Firefox. I have not modified the standard configuration of Firefox, or using any add-ons. The idea is to use an standard configuration. I tested in my Mac High Sierra and in a Ubuntu 16.04. Same results I switched the version to Firefox 57.0, and the tests are now always successful in both the Mac and in the Ubuntu, and the HAR file is generated every time. I attach images of the geckodriver logs with every case...Uploading of images fails.. :-(  !!!

I did not find any related issue in the support page.

Regards, Claudio

I could not upload the images with the error, so I copy the error message from the gecko driver log, as it may help:

console.error:
