Can’t find your Firefox web cache? Simple, type:

about:cache

into the address bar. This will give you your cache statistics. There are three sections:

• Memory cache - files in memory e.g. pages, css, images
• Disk cache - files on disk e.g. pages, css, images
• Offline cache - off lines files e.g. web site icons, downloaded java classes

Each section gives the memory currently in use and the maximum available. The the case of Disk and Offline cache the directory where those files are stored is given.

If you want to fish a file from the cache, there’s an easy but awkward way of doing it. Each of the sections lets you list the contents, so to get a file from the Disk cache click the List Cache Entries link. This displays a page which contains all the elements in that cache. Search for the one you want and make a note of the file size. At the top of the page the Cache Directory is given. Open that directory and order the files by file size. Match the 2 file sizes!

All the files in the cache will have cache file names like “4A62C7E5d01″ which are nice and easy for computers to read but useless for humans. When you think you have found the one you want, make a copy of it and rename it to it’s original file name.

Voila - you’re done!
