Find Downloaded YouTube Videos in Firefox's Cache

A lot of programs have the ability to download website content such as YouTube videos, flash games and more. But have you ever wanted to know how to do it? These steps will show you how to do it without any kind of program, using Mozilla Firefox Cache.

Steps

  1. Get Mozilla Firefox
  2. Make sure you have hidden files and folders option unchecked.
  3. Navigate to your User Folder and open "AppData" .
  4. Go to Local\Mozilla\Firefox\Profile, you will notice a random named folder whose name ends by .default. Enter that folder, then go to Cache.
  5. Open up Mozilla Firefox and reach the YouTube homepage.
  6. Load the video that you want and go to the cache. You will notice that a new file has been created with a 0 Kb space in it. Copy that file and wait until the video has loaded completely.
  7. When the video has done loading, paste the file within the clipboard to a desirable folder.
  8. Since the file has no extension you have to rename it and add .FLV at the end of it. The video is now ready to be played. For more details see tips.

  • Get Firefox by visiting and downloading from http://www.mozilla.com/en-US/firefox/
  • Many media players can not play such a file so you may have to convert it to a functional video file before trying to play it. Use a media converter software, such as FFmpeg.
  • You may want to clear your cache before going to the website. You can do that by navigating to "Tools" > "Clear recent history in Firefox".
