Viewing Browser Cache in Firefox

Firefox has a nice way to view files that are in both your memory and file cache. In the Address Bar, type – about:cache. This will take you to a page that allows you to view a summary of your browser cache and also will allow you to browse the files stored in the cache.

    If only we could delete individual cache files, through this interface …

    Do you know any plug-in for this?

    For firefox O.8, try “Profile Manager”.
    OS: WIndows XP
    go to “Start” on the taskbar->programs->Mozilla Firefox->
    Profile Manager->
    In new window: find “Create Profile”
    In new window: click “Next”
    In new window: click “choose Folder” and browse the location.
    In nen window: click “Finish”

    ok!
    I think that this is the single thread about Firefox cache and retreiving files from it. Can this be done?
    In a more usable manner than about:cache and seeing the filename that the loaded element is given in the cache directory.

    does this work with Mac OSX?

    Is it possible in Firefox to use a ramdrive to cache temporary internet files?

  10. Chris Myers said on January 19th, 2005 at 1:16 am

    Try looking here.
    C:WINDOWSProfilesChrisApplication DataMozillaFirefoxProfilesih2hc075.defaultCache

    Ofcourse, where chris is might be your name instead, unless your name is Chris also.

    I’ll just stop right there before I start rambling. Hope this helps someone/anyone

    My cache is located here:

    C:/Documents and Settings/JBowman/Application Data/Mozilla/Firefox/Profiles/default.udq/Cache

    Hope it helps!

    open a Firefox Browser and type ‘about:cache’

  13. whitespider said on April 26th, 2006 at 6:02 pm

    Works in Opera also.

  14. Suyog Gupta said on April 29th, 2006 at 12:57 pm

    Thanks for the information. This facility to view cache is helpful when you wish to find what requests a website has made in background. I used it when I had some doubts on a website that I used. I found all the requests it made, and entered all suspicious sites it requested in my Hosts file. Now, everything is peaceful.

  15. HylianElf said on April 29th, 2006 at 11:02 pm

    Won’t work for me. Especially since I need to find something out… I’m using the most recent edition (1.5.0.2) and when I go about:cache, nothing happens. :\

  16. MUDUX said on May 3rd, 2006 at 7:42 am

    I was really relieaved to find this thread about browser cache, I bet most of us here will be too….

    Interesting; my cache was in Documents and Settings\\Local Settings\etc. No wonder I couldn’t find it in Application Data. Hooray for about:cache

    Now when I’ve watched a Shockwave Flash video I want to save, I can browse to the cache in Windows Explorer, sort by file size, copy out the biggest files (usually 2-8MB), add .swf onto the end, and drag them into my browser to play them whenever I want.

  18. Roberto said on July 10th, 2006 at 7:00 pm

    Thank a lot for the ‘about:chache’ hint, that’s exactly what i was looking for

  19. Eddy said on July 19th, 2006 at 10:01 am

    why do you have to reinvent the wheel.. Internet Explorer works just fine and you can easily get the cached files such as movie trailers. Just go to temprary internet files, and there it is waiting for you.
    Firefox is stupid.. even when you view the cache files, you have to look for your file by size then rename its extension, wtf?
    If internet explorer works, I don’t have to listen to its haters saying firefox rocks!!
    cuz i can’t use firefox to do this simple thing

    Before reading any of this I found V-Com’s PowerDesk (~$35 bargain!)filemanager with Viewers let me find things in cache.

    My old V.5 with Inso QuickViewers displays .txt, .123 .xLs, .pdf, but not .swf. Anyway FireFox’s re-naming makes it hard to find them.

  22. wu said on October 27th, 2006 at 1:12 am

    Best cache viewer was early mozilla, I hate the fact that I can’t browse my cache..
    by doing about:cache you get lost in your cache it’s not really browsing…

  23. Cht said on November 14th, 2006 at 7:38 am

    The cache files are stored under
    \Documents and Settings\\Application Data
    \Mozilla\Firefox\Profiles\\Cache

    But they are not stored as in Internet Explorer. I guess that this if for some security privacy reasons. Yet, as Firefox is open source the fileformat can easily be broken.

    For more just check this website in securityfocus (there is a tremendous amount of information regarding Firefox Cache)

    Very handy tip, I’ve been wondering how to do this for some time. Thankyou!

  25. Canuck said on February 11th, 2007 at 12:56 am

    If you use the about:cache , you can then use edit/find for the file you need (ie. xyz.wav)in the disk cache section. It will find it, then click on the hyperlink and it opens another section of about:cache (cache entry infomation) that lists the full path and name of the file, size blah blah blah

    ie: \Documents and Settings\Local Settings\Application Data\Mozilla\Firefox\Profiles\3d5468a\cacheF66645795

    If its a pic you just click on the link and it opens the pic in your browser.

    of course since you are multitasking you already have windows explorer open to \Documents and Settings\Local Settings\Application Data\Mozilla\Firefox\3d5468a\cache\ and then all you do is right click on the filename you want, click open with mediaplayer (or recorder or….) and then save it from there with the right extension. Since you already know what filetype you are looking for of course you know what program to use to open it.

    The nice thing is IE people can never find your files or figure out what they are this way. Prevents nosy people from seeing what you have.

    I guess this is what me and everyone else on this page is looking for:

    CacheViewer 0.4.2: https://addons.mozilla.org/en-US/firefox/addon/2489

    Shows the entire cache & can sort according to size, key, device & fetch date. Also shows a preview and also has a search feature :-)

    I tried saving a youtube flv (flash video) file using this extension. It saves correctly but gives the get_video file a .htm extension which i had to manually change to .flv. Other than that its works fine.

  27. smiley said on May 18th, 2007 at 12:45 am

    yes! CacheViewer addon - finally I dont have to manually browse the msie cache to look for the files or the messy about:cache. THX Kartik Desai!

  28. bernard said on July 19th, 2007 at 5:45 pm

    thanks, very helpful

  29. B said on August 25th, 2007 at 1:46 pm

    Anyone use windows washer? You’ll notice when it shreds the cache - even when using mozilla - the actual stored files are in IE temporary internet files folder, the mozilla cache just stores browsing history. Seems quite pointless.

  30. Siobhan said on September 5th, 2007 at 12:57 pm

    How does one delete the files? Thx!

  31. Gary said on September 27th, 2007 at 3:21 am

    Siobhan - you will need to use windows file manger for this. The mozilla cache directory is a file subdirectory on your hard disk.

  32. vengy said on October 18th, 2007 at 8:19 pm

    I’ve extended the WebCacheViewer to show FireFox and IE history. Thanks.

  33. exc said on November 16th, 2007 at 2:15 pm

    Cache Viewer 0.4.3 doesn’t work for YouTube any better than VideoDownloader or Unplug. Nice little gadget, otherwise.

  34. a searcher said on November 26th, 2007 at 2:02 pm

    if a page (with dinamically changing content) was fetched in the browser 20 times, is it possible to recover an older version from the firefox’s cache?

  35. collector said on December 20th, 2007 at 12:19 pm

    Saved me hours. Thank you for the tip!

  36. queenofspades said on January 13th, 2008 at 3:19 pm

    can’t get this to work on my firefox 2.0.0.11 on mac os X 10.4.11
    any thoughts?

  37. Wayne said on February 28th, 2008 at 8:20 pm

    One web site that I access on a single networked computer continually recovers an old version of the site. I have cleared the cache, but the problem persists. A friend asked me about proxies on this computer, but to my knowledge there are no proxies set up.

    this XP, SP2 PC was purchased from the Dell used equipment store. Any ideas. Other computers in my office network access the current version of the site, but not the Dell box. Really strange.

    Any assistance would be most appreciated. Thank you.
