How to clean your cache in Mozilla Firefox 1.5, 2.0, and 3.0

Below is the full method, although it is possible to simply go to Tools, and select Clear Private Data, or to just press Ctrl+Shift+Delete. Please note that these options clear what you have set the browser to clear in Tools > Options... > Privacy, which can mean the cache, although it may also include passwords, and search and browsing history, so be careful.
