Answer 1

I got this error message while running tests in Visual Studio: Firefox simply wouldn't load and I got OP's error message.

I manually opened Firefox and found out that it needed to update itself (it did so before loading). Once finished I reran the test suite and Firefox showed up nicely, the tests were properly ran. If you get this error all of a sudden please try this answer before updating anything on your machine.
