The cache folder of Firefox (in Windows Vista or newer) is located under C:\Users\[User Name]\AppData\Local\Mozilla\Firefox\Profiles\[Profile Name]\cache2. Unfortunately, you can't browse inside the contents directly: here is analysis for the new storage format (cache2) , starting from in version FF 27: Mozilla Firefox Cache Folder Analysis

In order to access Firefox cache files you may either (I suppose you use the latest FF version, 47):

• use this free tool: MZCacheView

MZCacheView is a small utility that reads the cache folder of Firefox/Mozilla/Netscape Web browsers, and displays the list of all files currently stored in the cache. For each cache file, the following information is displayed: URL, Content type, File size, Last modified time, Last fetched time, Expiration time, Fetch count, Server name, and more. You can easily select one or more items from the cache list, and then extract the files to another folder, or copy the URLs list to the clipboard.
MZCacheView doesn't require any installation process or additional DLL files. Just copy the executable file (MozillaCacheView.exe) to any folder you like, and run it. After you run it, the main window displays the list of files currently stored in the cache of the Mozilla/Firefox profile that you used in the last time. If you want to view the cache of another profile, simply use the 'Select Cache Folder' option (F9), and choose the desired cache folder. You can select one or more cache files from the list, and than export the list into text/html/xml file ('Save Selected Items' option), copy the URL list to the clipboard (Ctrl+U), copy the entire table of cache files (Ctrl+C), and then paste it to Excel or to OpenOffice spreadsheet. You can also extract the actual files from the cache, and save them into another folder, You can do that by using the 'Copy Selected Cache Files To' option (F4).

• Alternatively in FF address bar type about:cache:
  click List Cache Entries and then search (via Ctrl+F) for instagram entries; clicking on each entry you'll get the URL of the original file and a hex dump of the local file from cache. Then you may follow this answer for converting the hex dump into a working file (you'll need two apps for that: HxD and Scite).
