In my image I have wired this for Windows to ShellExecute via FFI. One
could put it in a plugin as well.

Object subclass: #ExternalWindowsWebBrowser
   instanceVariableNames: ''
   classVariableNames: ''
   poolDictionaries: ''
   category: 'jr'

initialize
   "ExternalWindowsWebBrowser initialize"
   WebBrowser register: self.

openOnUrl: aUrl
   ShellExecute execute: aUrl asString.

Object subclass: #ShellExecute
   instanceVariableNames: ''
   classVariableNames: ''
   poolDictionaries: ''
   category: 'jr'

execute: aString
   self assert: aString isString.
   ^ self apiShellExecuteForWindow: nil
      operation: nil
      file: aString
      parameters: nil
      directory: nil
      show: 5 "SW_SHOW"

apiShellExecuteForWindow: hwnd operation: operationString file:
fileString parameters: parametersString directory: directoryString
show: aBitfieldInteger
   <apicall: void* 'ShellExecuteA' (void* char* char* char* char*
long) module: 'Shell32.dll'>
   ^ self externalCallFailed

In unix-land it uses the slightly scary xdg-open facility; I have no idea what the equivalent might be for other platforms but surely it must be doable.
