I’ve set up a WPT Private Instance which uses the Windows (wptagent) AMI to run tests. Chrome works fine, but if I try to launch a test with Firefox, I get a result of:
The testing completed but failed.
Invalid browser - Firefox
First View: Test Error: Invalid browser - Firefox
This occurs in all regions I have tested - us-west-2, eu-west-1, and ap-northeast-1.
If I remote desktop to the Agent, Firefox is installed and otherwise functional.
I’ve done more testing. It appears this is occurring because the browser_install.py file is downloading and installing the 64-bit Firefox, but something is wrong with the browser auto-detection in wptagent.py. This is evidenced by the logging, which only shows detection of Chrome, ie, and Edge.
If I manually install the 32-bit version of Firefox on the wptagent AMI, then Firefox works fine.
From the log file:
22:40:24.502 - Detected Browsers:
22:40:24.502 - Chrome: C:\Program Files (x86)\Google\Chrome\Application\chrome.exe
22:40:24.502 - Edge: C:\WebPageTest\wptagent\internal\support\edge\14\MicrosoftWebDriver.exe
22:40:24.502 - ie: C:\Program Files (x86)\Internet Explorer\iexplore.exe
22:40:24.516 - Microsoft Edge: C:\WebPageTest\wptagent\internal\support\edge\14\MicrosoftWebDriver.exe
Patrick fixed this with

Firefox now loads properly on the WPTAgent AMI.
