How to copy cookies from one browser to another - google-chrome

As the title says. How can I manually copy cookies to another browser so that I also have the accounts on the new browser?
I tried to copy the cookies with chrome developer tool but with no success.

Sharing the Realtime Documents

I have created a playground application. I see that it creates shortcut files in my google drive. I tried to share it with incognito (because I want the doc to be available to anybody and do not know how to create another google account, so I log out into incognito). The shared link looks like https://drive.google.com/open?id=0B00--A0eRH1JLTdsX2t0LWw5RE0. But, incognito fails to view it. It says that "No preview avaialable" in what is supposed to be its google drive window and offers the log in
The key problem that I see is that playground application has the following structure, which comes from the official demo
function onAuthorized() {
function onFileLoaded(doc) {display(doc)}
gapi.drive.realtime.load(your_doc_id, onFileLoaded)
}
// App entry point -- start by authorization
gapi.auth.authorize({
client_id: rtClientId, scope: ['install', 'file'],
//user_id: userId,
immediate: !popup }, onAuthorized
);
which seems to demand authentication in the first place before displaying any doc. Authorization is problematic for the unsigned mode that I want my app to be available. I want to share a file and make it viewable to the general public, without the need to log in. This raises a question if incognito users are able to view or event edit my document. I also concern how to copy the doc to their account if desired: one thing is when you have created a file on your drive with my app, you can probably list the files and use drive.copy api to copy desired one and other thing when you want to copy a file that is not available on your google drive and the only thing you have is its id.
BTW, can you tell me which account to use for non-incognito testing from another account? If I create the document in one account I want to see how it looks/accessible from the another.
The Realtime API does not provide anonymous access by default. See https://developers.google.com/google-apps/realtime/faq#does_the_realtime_api_support_anonymous_access
"BTW, can you tell me which account to use for non-incognito testing from another account? If I create the document in one account I want to see how it looks/accessible from the another."
Use Chrome for one account. Use Firefox and other browsers for succeeding accounts.
Additional note:
Just so you have a clear understanding what Incognito is all about. What it can and cannot do so you don't mix things up.
How incognito mode works
What you view
Incognito is a mode that opens a new window where you can browse the
Internet in private without Chrome saving the sites you visit. You can
switch between an incognito window and any regular Chrome browsing
windows you have open. You'll only be in incognito mode when you're
using the incognito window.
Be careful. Incognito mode only prevents Chrome from saving your site
visit activity. It won't stop other sources from seeing your browsing
activity, including:
Your internet service provider Your employer (if you're using a work
computer) The websites you visit themselves What you've downloaded
Chrome won’t save a record of the files you download in incognito
mode. However, the downloaded files will be saved to your computer’s
Downloads folder, where you and any other users of your computer can
see and open them, even after you close your incognito tabs.

How to auto-login website in chrome with saved password

Chrome is auto-filling the credentials, but not log me in until I click login. How to automate? (windows, non-google websites).
Using the Chrome Identity API you can have Chrome (on desktop and Android) automatically attempt to log in the user when they hit your page, even if their session has expired.
Following is a workflow diagram of how it works, but the details can be found in the Google Authentication API: Let the user automatically sign back in section:
It is not the browser's responsibility to auto-login to websites. This is the responsibility of the website you are accessing. The browser can remember form data and auto-fill for you, as can various extensions like LastPass.
However, in order to actually auto-login, you must first login to the website you are trying to access and enable the option they provide, often called 'Remember me?'. The website would typically use a cookie to store the credentials (securely with a hash + salt), and if the cookie still exists (not cleared from the browser or expired), and the hash of real password in database matches the one in the cookie, the website will auto-login.
You could force the browser to try and auto-login with extensions, which are essentially macros. You could try Auto Login or iMacros extensions for this. I would generally avoid this though.
Anyone else stumbling into this thread from a google search.... you can do this with autohotkey. If you browse to yourbankhere.com and chrome fills in the user/pass, you can have autohotkey perform a mousemove then a mouseclick to click the login button.

Completely forget a single domain in Chrome

How do I completely remove all data about a single domain in Google Chrome? (in one action)
Use case:
I am developing an offline web application, and frequently need to 'start fresh' while testing
Chrome's "Clear browsing data" can only be limited to time, not domains
Removing a domain's pages in history does not remove service workers
App Cache doesn't work properly in Chrome's Incognito mode
Ideally, a UI button or keyboard shortcut would be best. Extensions are fine, if they work.
Please don't submit answer unless service workers are also removed (I know there are many solutions for cookies/cache etc).
thanks
Chrome now includes a 'Clear storage' function in the 'Application' tab of dev tools (using v52). Thanks Chrome!

What does Chrome's "Incognito Mode" do exactly?

I was under the impression that Chrome in Incognito Mode wouldn't accept or send cookies, since they could be used to identify you. When starting up Incognito Mode, I do have to re-log-in to gmail, etc. But the log-in stays active during the session.
So it seems to me that Incognito Mode maintains a separate, temporary store of cookies which get destroyed when you exit incognito mode. Does this mean that, if you browse in Incognito Mode all the time, it would have no benefit? Does Incognito Mode do anything else?
It essentially sets the cache path to a temporary folder. Cookies are still used, but everything starts "fresh" when the incognito window is launched. This applies all storage, including Cookies, Local Storage, Web SQL, IndexedDB, cache, etc.
Of course Chrome also leaves pages out of the browser's history.
As a developer, it is also interesting to note that Incognito DOES NOT create a separate data partition for each window or tab.
All windows and tabs share access to the same cookies, so you can't create separate tabs to simultaneously log in as different users to one system that uses cookies to transmit authentication info.
Based on this, you still need to use a different browser to test this scenario.
Just an important privacy note on #Jared Dykstra answer and #Mark comment.

Not 100% true
Today I opened a new fresh chrome incognito window and requested youtube.com . but I surprisingly found that youtube is recommending some videos to me!!! How? based on what ? I'm supposed to be a very new client with fresh browser - I noticed the recommended videos was based on the videos I usually watch while signed in to my google account from chrome or firefox -
After investing the cookies I was shocked that chrome is sending these cookies to youtube.com along with the very first request send to youtube.com from a new freshly opened incognito window.
GPS
PREF
VISITOR_INFO1_LIVE
YSC
I guess youtube.com servers used these cookies to know who I'm and recommend videos for me based on them.
I checked Firefox and it does not do that, it starts the private windows with 100% empty cookies header!
Chrome's incognito mode sets the cache to a temporary folder. When you close the browser window the folder is deleted. So all your history, logins, and downloads are forgotten.
Incognito does not stop sites from keeping information about your visit nor does it hide the browsing from people using a tool like Wireshark to see what you are viewing.
The accepted answer is great. Just adding a note that Chrome has a setting to block third-party cookies while in incognito mode. See the description of the feature released May 19, 2020 in Chrome 83.
Block third-party cookies in Incognito mode (Computer)
You can now block third-party cookies from ads and images on pages you visit in regular mode and in Incognito mode.
And more from the product team:
In addition to deleting cookies every time you close the browser window in Incognito, we will also start blocking third-party cookies by default within each Incognito session and include a prominent control on the New Tab Page. You can allow third-party cookies for specific sites by clicking the “eye” icon in the address bar. This feature will gradually roll out, starting on desktop operating systems and on Android.
If you don’t want Google Chrome to save a record of what you visit and download, you can browse the web in incognito mode.

chrome extension: open an website with different account in each tab

I have several accounts for a website and currently I want to write an extension that I can open all the accounts simultaneously in chrome, each tab for one account.
So that means I want each tab with a separate cookie system, is it doable? If so please suggest the API I should use, thanks!
Go to Chrome Preferences. There is a Users section where you can add users. Each new user will have its own cookie jar, so you can log in to a site as many different users at once. It makes new chrome windows, but it seems you cannot drag a tab onto a window of another user.
According to Chrome documentation, you can modify HTTP headers (including cookies) in the onBeforeSendHeaders event handler. So, you need to store new cookies for every account by means of the onHeadersReceived event handler, and then substitute them for every tab in outgoing requests.
There even exists an extension which seems doing almost the thing you want - Chrome Cookie Switcher.
Also I have found an answer that may be helpful for your task: Associate a custom user agent to a specific Google Chrome page/tab.
I really don't think Chrome allows extensions to do this. If I recall correctly, extensions can inspect and block requests, but they can't modify them, such as changing cookies on the fly for each tab.
I suggest you use the --user-data-dir command-line option of Chrome. It allows you to keep several separate profiles, each in its own directory, and then you only need to start chrome with the proper option:
# run this command to use the first profile
google-chrome --user-data-dir=/home/binchen/my_chrome_profiles/my_profile_1
# run this command to use the second profile
google-chrome --user-data-dir=/home/binchen/my_chrome_profiles/my_profile_2
...
Each profile will be in its own Chrome window, with its own cookie store, instead of its own tab, but it's easier than writing an extension.
Lastly, if the website you're mentioning is Google, you can keep several Google accounts open at the same time.
