FireFox Error "Cannot find any existing or open blank page"?
We have a test with a browser loop containing Chrome, IE, FireFox. The test runs fine in Chrome & IE, but FF gets "Cannot find any existing or open blank page" when navigating to our main site at the beginning of the test. We are able to navigate to the site manually outside of TC in FireFox without error.
Go to Help -> Check for Updates and make sure you have the latest Firefox support update. I think something has been released recently so it might be worth the check.
