This page is dedicated to optimizing Firefox 3.x in LTSP/Multi-user environments. It seems that Firefox 3.x development is focussed more on single-user setups than multi-user networks, especially LTSP type environments. Luckily, there are a few things you can do to make it run better under LTSP, by editing the following file (please note that these options have not been fully tested, but the instances where they were showed noticeable improvement in LTSP environments):

/etc/firefox-3.0/pref/firefox.js:

// Disable "safe browsing" feature that hogs CPU, HDD, etc. etc. in LTSP
pref("browser.safebrowsing.enabled", false);
pref("browser.safebrowsing.malware.enabled", false);

// Disable "location-bar suggestion" feature that is sludgy with thin-clients
pref("browser.urlbar.maxRichResults", 0);

// Disable offline/disk caching of web pages - good if you have a central proxy
pref("browser.cache.offline.enable", false);
pref("browser.cache.disk.enable", false);

There are also some great ways to customize Firefox behavior all around for specific environments - here are some good ones, but you can check out http://kb.mozillazine.org/About:config_entries for a complete list..

// Disable password manager
pref("signon.rememberSignons", false);

// Disable session restore - useful when users log out without closing Firefox first - saves server
// CPU, memory and bandwidth when they restart Firefox and open up lots of tabs from previous session
pref("browser.sessionrestore.enabled", false);
