[gentoo-user] Firefox and Thunderbird spell-checker is offering too many languages

[Nikos Chantziaras]

The list of spell-check languages offered by Firefox and Thunderbird 
looks like this:

  English (AU)
  English (CA)
  English (GB)
  English (GB-oed)
  English (NZ)
  English (US)
  English (ZA)
  German (DE)
  Greek (GR)
All this English stuff needs to do away, I only want English (US).  Is 
there a way to do that?
