Where can I find the Firefox cache. It has disappeared for the old location.

Posted

I frequently viewed the Firefox cache. When I first got FF 4.0 they had complicated it a lot, but I could still find it. As of today -3/30/11-I cannot find it at all.

You can find the location of the two caches on the about:cache page (open that page via the location bar like a website).
Only large image and media files are stored as individual files on disk.
Other files are stored in a few large container files (_CACHE_XXX_) in the cache folder and not as separate files on disk.
The individual files on disk have random names without a file extension for security reasons: you can't open an application or start a downloaded virus inadvertently by clicking a file in the cache folder.
Firefox 4 uses a more sophisticated file structure and creates many subdirectories in the main cache folder to make it possible to store files in the cache.

I really appreciate your reply.

"about:cache" entered in the location bar does nothing, no error message, just nothing. Yesterday, using FF 4, I could find the cache folder which had folders 1-9 and A-E (I think) and each had many folders in it. All the files I wanted to see were in those folders. Today the cache folder has disappeared completely, at least from that location.

Original cache folder was located as follows: Users:myusername:AppData:Local:Mozilla:Firefox:Profiles:hrd4zfxh.default:cache

Did you check the location of the default profile to see if the cache has been moved?

  • Help > Troubleshooting Information > Profile Directory: Open Containing Folder

Are you running Firefox in Private Browsing - Use Firefox without saving history mode?

  • To see all History and Cookie settings, choose: Tools > Options > Privacy, choose the setting Firefox will: Use custom settings for history
  • Uncheck: [ ] "Automatically start Firefox in a private browsing session"

Is the cache still enabled?

  • Firefox (Tools) > Options > Advanced > Network > Offline Storage

You can also check these prefs on the about:config page.

I found the cache of the FF4, but it not was useful. (In the "local settings/application data/... " there is anywhere, I don't remember, because I installed back the FF3.6.15

The cache problem of the Firefox: it can store into the cache below 66MBytes only, and no more.

The Firefox version 4 also can't store bigger files, and additionally it has a very problematic feature: the thousands of different subdirectories, which are not surveyable, and a little bit confused.

It's operation was a little bit buggy, so I try to keep the older versions of Firefox, as far as possible and a little over...

(Remark: the caching of the different web browsers are very different: the best is the Internet Explorer, the worst is the Google Crome, between what I tried.)
