Currently, logging is performed into app console & into standard out stream (using dump()).

On Windows, you might want to use one of the following approaches (e.g., using Firefox Developer Edition):

1. "C:\Program Files\Firefox\firefox.exe" > "C:\Users\you\f.log" &:: pipe to a file
   And then tail it (e.g., using Cygwin):
   tail -f "C:\Users\you\f.log"
   OR
2. "C:\Program Files\Firefox\firefox.exe" -console

[1] To see dump() output on Windows with -console argument (approach 2. above), browser.dom.window.dump.enabled pref needs to be set to true (manually, since Mozilla no longer allows extensions to change apps' preferences):
