"There was an attempt to perform an action on a zero-sized window." error message in FF only
I am getting an "There was an attempt to perform an action on a zero-sized window." error message in Firefox 98 in my python script. This script has been run in Chrome, IE and Edge without any issue...
If the test works when you step through it, then I agree we are looking at a timing issue. Try checking for Exists and Enabled on that logout button before you click it and see what happens.
