TB hangs after a windows says that nsPreferences are missing when sending an email

After composing a mail message and pressing Send, a dialog indicates [Javascript Application] Preference Error Reference Error: nsPreferences is not defined.

Very often (but not always) this does not interfere with the sending process. But with the most recent update of TB, about half the time pressing the OK button hangs TB. The only solution is to force quit it, relaunch it and recompose, all while hoping it will not hang this time.

VERY ANNOYING !

What is the solution, please?
