user_pref("browser.cache.disk.enable", false);Voila! The trick of the week! I got it from Rahmcoff (Peter of the Norse) over at the Chimera board. Note that the "12345.slt" folder will actually be named something else on your machine; you want the folder that ends in .slt ... and you may have a folder with your username instead of "Default."
[Editor's note: I haven't tried this one myself yet, and I would assume the option to disable disk cache will eventually make its way into the normal Chimera Preferences panel.]
