Probeer eventueel eens een user.js in de profieldirectory van Firefox te zetten die de boel wat optimaliseert.
Ik gebruik dit:
user_pref("browser.block.target_new_window", true);
user_pref("browser.tabs.opentabfor.middleclick", true);
user_pref("browser.tabs.opentabfor.urlbar", true);
user_pref("browser.display.show_image_placeholders", false);
user_pref("browser.xul.error_pages.enabled", true);
user_pref("network.http.pipelining", true);
