@JerryGoyal turns out that commas are special in PowerShell: https://stackoverflow.com/questions/11990688/powershell-is-removing-comma-from-program-argument

So you need to add quotes:

# This WILL NOT work
firebase emulators:start --only functions,hosting

# This will work
firebase emulators:start --only "functions,hosting"

@samtstern I see, that shouldn’t be happening. I am using PowerShell 6.2.3 (https://aka.ms/pscore6-docs) in VSCode. so, should I file the bug in PS repo?
