You can access your FireFox cache files by typing this "about:cache?device=disk" into your FF URL bar

There is the cache directory will tell you the directory in which cache is stored, this is not IE and you'll not be able to browse by going to that directory, because its in encrypted form. If you want to browse your cache, you're in the page!

The about:cache?device=disk is the disk cache page! browse around in here.

This is completely different to what is temporary internet files in IE.

Use the quick find function by pressing / (forward slash) and type in keywords to go a particular element in cache, Use F3 to go to next search result .

Use Shift+F3 to go to previous result.

hey mate!
that is really cool option you can access through firefox. there is also one more way to access your cache, and even find some downloaded movies or videos on your computer. just show your hidden files go to c:\documents and settings\application data\firefox. Of course this is not proper root, as i can't really remember proper root couse there is so many application datas and users on computer, but if you browse those folders for a while i'm sure you can find it!

really want something different? i used drive D:// as my cache..,
Specify where to store the cache. To specify in which folder the cache is stored, use about:config to add the String preference browser.cache.disk.parent_directory, and set the value to D:\firefox_cache.
