Many users know how to get videos and music off existing sources that were designed to be viewed live, eg youtube, whether it’s using a downloaded program or a 3rd party website that rips the content and allows you to download it.
Users wanting to download somebody else’s video of Facebook will realize this isn’t possible, and third party methods are most probably ruled out because of privacy settings.
There is a way though, using your browsers (Firefox in this case) cache. A cache is a copy of something that your computer stores enabling you to access it faster next time, without the need to re-download the content from the server.
- Go to the video page using Firefox, don’t play it yet.
- Click the Start button, click your user name that you’re logged into Windows with. eg mine is LEthaLity. You should see a folder called AppData, if you do skip to step 4, if not, read on.
- You need to enable the viewing of hidden folders, click the organise button in the top left, ->Folder and Search Options, then click the View tab, under Files and Folders there’s a “Hidden files and folders” option. Click the radio button enabling “Show hidden files, folders, and drives”. Then click Apply, and ok, you should now see AppData.
- Enter AppData, then click Local->Mozilla->Firefox->Profiles. You will then see a folder named in the following manner “imm40evz.default”, the bit before default will probably be different for you. Enter this folder, then go into Cache.
