Remote Desktop question concerning TC web using a node license and Firefox

First thing to find out would be if the test works correctly on the remote machine when you are actually logged into it as a primary user (without remote desktop). If that works then refer to this article : https://support.smartbear.com/viewarticle/72139/

It shows us how you will be able to minize the remote desktop after kicking off the test and continue with your work on your PC while the tests continue to run on the remote PC.

I have implemened this and it works great.
