Only a system administrator can override the optimized values that are set for the Mozilla Firefox web browser. The optimized values are present in the /usr/lib/firefox/defaults/pref/all-multi-user-desktop.js file.
The following code shows the values in the all-multi-user-desktop.js file.
// Disable "safe browsing" feature that hogs CPU, HDD, etc.
pref("browser.safebrowsing.enabled", false);
pref("browser.safebrowsing.malware.enabled", false);
// Limit the "location-bar suggestions"
pref("browser.urlbar.maxRichResults", 3);
// Disable offline/disk caching of web pages
pref("browser.cache.offline.enable", false);
pref("browser.cache.disk.enable", false);
// Change the default cache:
pref("browser.cache.memory.enable",true);
pref("browser.cache.memory.capacity", 1024);To override the optimized values present in the all-multi-user-desktop.js file, create a new file in the /usr/lib/firefox/defaults/pref/ directory with new values. The file name should be alphabetically higher than the all-multi-user-desktop.js file. For example, you can name the file as all-admin.js.
