Multi-window mode is longer used as an option and will be ignored.

This is the code that I am trying to execute via Powershell:

C:\Progra~1\Java\jre1.8.0_111\bin\java.exe -jar D:\PubApps\DBA_Global_Reports\DBA\Powershell\DataExport\selenium-html-runner-3.0.1.jar -htmlSuite '*firefox' 'https://TestSite_URL/' 'D:\PubApps\DBA_Global_Reports\DBA\Powershell\DataExport\DataExportOpenTicketsSuite.html' $TestResult
 (get-content $TestResult) | Foreach-Object {$_ -replace $pwdEnc,"DBAPWD"} | Out-File $TestResult

Browser attempts to launch, then fails with the above error.  At a minimum, need to know how to execute Selenium IDE Tests using Selenium HTML Runner 3.0 on FireFox versions 49+.
