Does anyone know of a browser which has unique cookie storage for each tab? Or maybe some plugin for popular browsers which will add this feature?

I want to use different tabs to logon in one app as different users.

IIRC cookies are stored per domain, thus if you have example.com open in 2 tabs, they will share cookies. Can I ask why you want to have different cookies in each tab? Are you trying to login to the same application in multiple tabs as different users? –  scunliffe Nov 27 '10 at 14:11
    
@RAMe0 Are you setting the cookies manually with JavaScript? –  Šime Vidas Nov 27 '10 at 15:01
    
@scunliffe You are right. I want to use different tabs to logon in one app as different users –  RAMe0 Nov 27 '10 at 16:34

This isn't quite different tabs, but in the past I would use two windows - Regular Chrome in one window, and incognito in another, and each with a different gmail account.

Alternatively, one could make OS user profiles and launch chrome in them,

But i've found a better method in Chrome. Click the chrome menu, then settings, search for user chrome://settings/search#user

And you can create new [chrome] user profiles i.e. within Chrome.

enter image description here

c:\Users\user\AppData\Local\Google\Chrome\User Data\Profile 1 c:\Users\user\AppData\Local\Google\Chrome\User Data\Profile 2 e.t.c.

Then get different icons in the taskbar (Notice one white head, one blue head, 'cos those are the icons I gave the two users)

I don't think there are any browsers with this exact feature built in.

Most modern browsers however will let you start some kind of private browsing session (called incognito in Chrome, and InPrivate browsing in Internet Explorer). In private browsing the cookies are separate from the normal browser session, and are deleted when you close the window.

Firefox won't let you open a private and "normal" window at the same time, but chrome and IE will. This will let you log in as one user in the "normal" window, and another user in the private window. (I frequently do this at work for some internal applications that tend to write over each others cookies)

This will only let you do two users at a time, but it's better than nothing.

Sounds like what you want is the MultiFox extension for Firefox. It's not perfect (browser limitations mean you have to have one window for each identity) but it's pretty darn good, all things considered.

Simply click the "Open in a New Identity Profile" menu entry it adds, log in, and you're good to go.

Another option which isn't updated for Firefox 4 yet but should be soon is CookieSwap which gives you a statusbar icon that lets you swap between different credentials in the same window, but doesn't let you keep multiple ones active at the same time the way MultiFox does.

You can use Lunascape it is a triple engine browser so you can set one tab to use Gecko one Webkit and one Trident. In other words Firefox/Chrome/Internet Explorer rolled into one.

Trible browser engine does not mean trible cookie storage. Do the engines store cookies in different places in this browser? –  Kissaki Jun 12 '11 at 13:22
    
@Kissaki Well who cares.. obviously he means they store cookies separately at least logically. It's an intelligent suggestion and sounds like he has tried it. I'm trying it –  barlop Oct 29 '11 at 5:01
    
yes, not surprisingly, arctor got it right.. he sounded like he knew what he was talking about and he did. –  barlop Oct 29 '11 at 6:55

Chrome Sync can sync between Chrome, Chrome Canary, and Chromium on one macine. Chrome Canary is unstable, and I haven't tested Chrome and Chromium at the same time.

In Chrome Canary you could also enable profiles, and have two different windows with different profiles. (No tabs, sorry, I think)

Since your intentions are really to login to the same application as 2 separate users there are a few options. Since all tab browsers share a common session so that you can have multiple tabs open to the same application as the same user, you'll need to overcome that by trying one of the following:

  1. Use 2 different browsers. E.g. Use Google Chrome & Mozilla Firefox (since there is no way that 2 different browser applications can share the same session data
  2. Launch a brand new instance of the browser (I'm not sure which browsers this does work in, but I know it works in Internet Explorer). E.g. Start > Programs > Internet Explorer
  3. If you use an addon like IE Tab for Firefox, you can use it in one tab. (thus similar to #1 above, you are using 2 separate browser engines... it just happens that one is rendering inside the other.

Maybe #3 will work. But it have some bad sides: Firefox going to use too much memory (after couple hours of work). As usual I have about 15-20 opened tabs + using min 3 tabs with IE engine = for about 500M-1GB of memory :( –  RAMe0 Nov 28 '10 at 1:37
