I think you're looking under:
Edit->Preferences->Content->Languages-Choose

The GB & SA English packs that were causing my grief are under:
Tools->Add-ons->Languages
  Or
Edit->Preferences->Manage Add-ons->Languages

I'm running a 3.2 GHz P4 with 1 core, 2 hyper threads, and 3.2 GB of 
Visible RAM.

Performance is generally not an issue, especially now that I've disabled 
the language packs. It's possible that every web page was being filtered 
twice, making a pointless thing worse.
