I've attempted to switch my Selenium Test build to the VS 2019 build image, however, when I do so, I get the following error:
[00:02:16] Initialization method MathsPathway.Tests.UI.**.Setup threw exception. System.InvalidOperationException: Failed to start browser C:\Program Files (x86)\Mozilla Firefox\firefox.exe: no such file or directory (SessionNotCreated).

My setup follows the instructions at https://www.appveyor.com/docs/how-to/selenium-testing/ which have been working on the VS2017 image.

Do I need to change the Firefox install location? Or specify it differently for that image?

    Hi Sean,

    On VS 2019 image there is x64 version of Firefox in C:\Program Files\Mozilla Firefox\firefox.exe.

    You can do a check like in this test: https://github.com/appveyor-tests/selenium-tests/blob/master/Seleni...
