Use Firefox's cache viewer to view object

How to save bandwidth with firefox?

 Method 1:

Use Firefox's cache viewer to view objects in the cache which are images, flv,flash etc


1.  Put Firefox into *offline* mode

        File � Work offline

    You will need this for step 4 below.


2.  Open Firefox's built-in cache viewer by entering the URL
        about:cache
    then click on the link "List cache entries"

    You will now see a list of URLs in the cache.


3.  Click any one of the URLs to view the more detailed Cache Entry Information
    for this cache entry.

    FWIW I prefer to use 
            (right-click) � Open in New Tab
    because that way it is quicker to go back to the cache listing.


4.  Click on the link next to "key:" at the top of the detailed page.

    If you are in off-line mode (see step 1), then Firefox will view
    the object in the cache. 

    If the object is an image, Firefox will view the image as an image.

> [...] they're encrypted files.


A.  "files"

    Some of the objects in Firefox's cache do not even have files of their own. 
    Only large objects get files of their own.  Small objects do not get files
    of their own; instead they are embedded inside one of the cache files
    _CACHE_001_, _CACHE_002_, _CACHE_003_. 

    On the Cache Entry Information page (step 3 above), if it says
        file on disk: none
    then you know the object does not have a file of its own.

    I would guess that this saves disk space.  For small objects, the overheads
    of rounding up to the cluster size would be large.


B.  "encrypted files"

    To be accurate, they are not encrypted *files* -- the are encrypted *filenames*.
    (And of course, this only applies when the object gets a cache file of its own.)
