848355 2010-01-13 19:19:00 The sites you go to. The same as what IE does. I would update FF. Its up to 3.57 now Speedy Gonzales (78)

848357 2010-01-13 20:01:00 Essentially, FIrefox (and other browsers) keep a 'carbon-copy' of each site you visit. Why? So that if you go there again you can save time and bandwidth by not having to re-load the entire site each time. The basic outline of the site (the HTML) needs to be re-loaded and examined for evidence of any changes, but if it's unchanged, then the browser knows it can pull the rest of the files (images etc) off the cache on your hard disc.
They get renamed in the caching process, and don't have a file extension, but with the right software you can browse through your cache.
Certainly by file size, it's the images that are the key target for caching.

They also provide another way of evaluating what sort of content users have been browsing, so for some it becomes an important privacy issue to clear the cache.
Clearing the cache does not clear stored passwords.
