I used to locate the file data by going to cache directory, which I would locate by typing
about:cache in the firefox address bar. I can still navigate to this page but the file structure inside his has changed. Earlier I would take, say for example a file of maximum size and rename it to .flv to get it working as a video file. Now I am unable to locate this video files. does anybody have any idea as to where would you find the cached files in firefox(say you watched a video in youtube) and now you want it to access offline.
