CookiePie an innovative Firefox extension released

Sebastian Wain from Nektra has submitted CookiePie extension to Firefox Extend Contest with great expectations to be one of the finalists, since it is an innovative piece of software and push beyond the standard capabilities of Firefox. Although it doesn’t came finalist he waited for the announcements to release it publicly without publishing it on Internet until now.Mauro Asprea from Nektra has been contributing on improving user experience.

  • What is CookiePie?
    • CookiePie is a firefox extension enabling you to maintain different cookies storage in different tabs and windows.
  • How I can obtain and use it?
    • Download it from: CookiePie Extension
    • Use the tab context menu to enable CookiePie
    • For example: Toogle CookiePie in three tabs, and login to different GMail account in both.
  • Where the idea came from?
    • We need to use it internally at Nektra, and finally decide to publish it for the community.
  • What does CookiePie means for the end user?
    • It means that you can for example open multiple GMail/Yahoo Mail/Hotmail accounts in different tabs and windows simulteanously.
  • What does CookiePie means for web developers?
    • Developers working on Web Software supporting multiple users or profiles can use CookiePie to simultaneusly test their software with each user without needing to open a different browser.
  • How CookiePie was made?
    • A first look at the FireFox extensions capabilities let us think this extension was almost impossible to do. One of the limitations was the unconnected parts between http transactions and UI being difficult to correlate an UI to a specific http request/response, more when AJAX/XmlHttpRequest (i.e: GMail) is involved.
    • The work involved mainly short term research and trying to push to the extreme FireFox capabilities without knowing nothing of Mozilla Extensions at the start of development.
  • What are the current known limitations:
    • Gecko 1.8.1 has some implementation errors: FireFox store cookies although our http observer changes the response header. This means the common cookies are changed in the FireFox extensions for every transaction on each tab. More information at: Mozilla Bugzilla
    • The reordering of tabs is breaking GMail account opened tabs.
    • GMail has added after we finish this extension, an alert we hope to repair it so GMail doesn’t know about another connection on another tab or window.
    • User may experience problems with another Firefox extensions (for example Tab Mix Plus)
  • What are the features we would like to have in the future?
    • Listen to users feedback.
    • Complete Cookie commitment to standards/security
    • Compatibility to another extensions.
    • Add configuration options
    • Enable CookiePie by default
    • Cookies inheritance checkbox: If a user opens a new tab/window from a CookiePie tab, the new opened tab can inherit the cookie container.
    • Cookie pipeline handling: Have a configuration like the Firefox option to choose what cookies needs to be individualized and what cookies needs to be used from the firefox container.
    • Persist/Save/Load Tab Cookies
    • Code: better & cleaner.
    • Testing: Test & Fix in complex scenarios.
  • What we suggest for future versions of Firefox?
    • We suggest to have this capability embedded natively on Firefox and not as a third party addin. We know this will involve changing relations between objects in Firefox but it’s an obvious step to do in the browser war.
  • What platforms are supported?
    • Currently it ran fine on Windows and Linux. We need to check why Mac is not supported because this software is standard JS code, not platform dependent.

    I agree: thanks a lot for the plugin so far! And: a version for 3.5 would be GREAT 🙂

  • Jim Kramer

    Yeah! Someone has to do something about 3.5. Booyah

    Please help me out.

  • Mohan raj

    I am using firefox 3.0.10. can cookiepie can be installed in this version

  • Brian Hendel

    Firefox 3.5 compatible version please! : )

  • Casey Steuber

    ^ agrees with Brian…3.5 won’t let you install. This would be, really, the death of IE on my computer. As I would really have no reason to keep it after this…

  • olo

    Please, repair this soft for Firefox 3.5 or highter.

  • Jason

    Another 3.5 request.
    Great software.
    Cheers from Michigan.

    See the announcement at:


  • Syed

    Installed the version 1.0.4, but it is signing out of cookiepie’d GMail immediately after signing in. Please help!!

  • Max

    Starting last week, If I turn on cookiepie, cannot access facebook from firefox. Facebook kept on asking for user id and login. Upgrading to 1.0.4 does not help.

    Any idea?

  • johny

    Max, i do have the same problem.
    Maybe Facebook blocked it 🙂

  • christianbelouve

    I’m currently using CookiePie 1.04 with Firefox 3.5.2, and the opened tab from the CookiePie-enabled tab don’t have CookiePie-enabled. Hope someone will fix this 🙂

  • max

    hi guys when are you going to create new version?mozilla with 1.04 constantly asking enter password in yahoo mail.please fix it.

  • Bob Barr

    Hi dude! It does not work with FF 3.6. What is up with that?

  • Spirit

    Yes, doesn’t wor with 3.6.

    And I have some “bugs”:
    1. When whe change the position TAB addon stops working.

    2. Sometimes the data entered into forms are not sent, but I can not determine exactly when this happens, the only solution is starting browser and use addon again.

  • Bob Barr

    Folks…. I found a way to get around it. Booyah

  • How Bob???

    Bob, care to share???

  • vitthal patil

    can you please provide such kind of functionality to IE browser

  • PMP

    Would have been nice of Bob to share. He was willing to ask for help and wait to get it but not willing to share once he found a solution. Whats up with that?

  • Carlos

    Por favor actualicen la versión de Cookiepie, no funciona bien en el nuevo FF.

    Es demasiado útil esta extensión como para perderla.


  • John

    This could be one of the most popular addons ever, but I know many users (including myself) that will not install addons that are not on the official Mozilla website.

    So… why is this not on the official Mozilla website???

  • Pro

    Why i can not find it on mozilla add-ons directry?

  • Mark

    Why is this not on the offical Mozilla add-ons site?

  • michael

    It does unfortunately not work if there is a redirect after a cookie is set. rdirects after login to

    But the cookie (for is not available from

  • Works like charm, on FF 3.6, Vista. Guys a huge thumb up!
    You have no idea how helpful it is for me!

  • Spirit

    I have a question for devs or users.

    CookiePie work good, but I have some problem. When I was in the page and use AJAX (to get another page on the same domain) I get empty page (because cookie was deleted and I get start page – loged out).

    Any solution? I know I can go normal to the page, but AJAX is more comfortable.

    For developers. You write:

    Cookies inheritance checkbox: If a user opens a new tab/window from a CookiePie tab, the new opened tab can inherit the cookie container.

    I think that is a problem, are you developing the project further, it will be implemented?

  • Jayadi

    Thanks for this plugin..
    firstly I log on my 1st FB account, next I open new tab, and activate cookiepie, then log on my 2nd FB account…
    unfortunately, I don’t have full access to give comment on the 2nd account….
    what should I do..?
    thanks for your response

  • russ

    I am trying it in FF 3.6.13, and each time I log on to my 2nd yahoo account, it asks for my password. I enter it, and it shows me my folders. When I click on a folder to open it, or try to compose an email, it asks again for my password. Every time!

  • Sam

    I just tried this with YouTube and unfortunately it does not work. Would love a similar eature for managing multiple YouTube accounts. Anyone? 😉

    Thanks for the extensions anyway it’s a great idea!

  • Bob Barr

  • I am looking forward to a comparable with FF4 🙂

  • Bob Barr

    Folks! Bob is here. It is not working with FF4. What are we going to do, folks?

  • Bob Barr

    Bob just tried it with FF4 and it still did not work. Bob is very upset right now. Folks! we have to do something about this.

  • NervousMan

    Folks! Bob is back again. There is no progress on this still. Bob is very upset about it. What are we going to do, folks??

  • Rudolf Stomps

  • Bob Barr

    Yes! Bob can confirm that it does not work for FF 5.0! What a shame! CookiePie is coming to end.

  • Xorax
