How can I move the location of Firefox's cache to another drive to free up space on Cdrive? ↓ Show more All postsHelpful Solutions solution owner post helpful post post TonyE 2 years ago You can do this by creating a new hidden preference.

Type about:config into the location bar and press enter Accept the warning message that appears, you will be taken to a list of preferences Right-click somewhere in the list and select "New > String" For the name of the preference type browser.cache.disk.parent_directory For its value type the path to where you want to store the cache Next locate the preference browser.cache.disk.enable, it must be set to true, if it is not, double-click on it to change its value For more information on this see http://kb.mozillazine.org/Browser.cache.disk.parent_directory (the mozillaZine knowledge base is down at time of posting, but should hopefully be back up soon)

Use the Google cache in case of problems accessing the mozillaZine knowledge base (prefix links with cache:)

Note that this is a hidden pref that doesn't show by default on the about:config page and needs to be created as a new String pref as posted above.
