I am able to see session cookies in Firefox 3.6 by going to
Tools->Options->Privacy->Remove Individual Cookies
How do I see those same session cookies in IE (6/7/8)?
Tools->Internet Options->Browsing
history Settings->View files
only contains persistent cookies
Also how do I access them programmatically? In Firefox I use the nsICookieManager interface to read the session cookies, does IE contain an equivalent interface?
Cookies set with the HTTPOnly attribute will not be visible to Javascript (e.g. via the document.cookie accessor). In IE8, 9, and 10, hit F12 to open the Developer Tools. Click Cache > View Cookie Information to see persistent and session cookies that apply to the current domain.
This feature is not present in the IE11 version of the tools, which would mean that your choices are 1> Watch outbound Cookie headers in Fiddler or on the Network tab, or 2> Write a plugin that calls the InternetGetCookieEx API with the appropriate flag to include HTTPOnly cookies.
Type into adress-bar:
javascript:alert(document.cookie)
to see the cookies that are currently readable by javascript.
Regarding to the read/write of session-cookies:
Why do you need to do it using javascript? usually session-cookies are needed to have an relation to serverside stored data, so you need to manage the cookies from serverside, no matter what browser there may be.
F12-> Network Tab -> Enable Network Capture Traffic Capturing - > Details Tab -> Request Header Tab.

I am attempting to follow the new guidelines for Cross Site Cookies and passing the SameSite=None; Secure attributes with cookies as I attempt to set them in browser Javascript code.
We are sending our SSO/Authorization javascript bundle from a separate host and domain that is supposed to set a cookie in the browser for storing the sessionToken. This cookie is then expected to be used on a browser refresh to maintain the users session.
Since updating to Chrome 80 the cookie is no longer saved in the browser due to the following error:
A cookie associated with a cross-site resource at <sso_domain> was set without the
`SameSite` attribute. It has been blocked, as Chrome now only delivers cookies with
cross-site requests if they are set with `SameSite=None` and `Secure`. You can review
cookies in developer tools under Application>Storage>Cookies and see more details at
https://www.chromestatus.com/feature/5088147346030592 and https://www.chromestatus.com/feature/5633521622188032.
We are using js-cookie to set the cookie which uses the browsers document.cookie to actually create it: https://github.com/js-cookie/js-cookie/blob/master/src/api.mjs#L38
Initially we were not passing the SameSite attribute through the attributes param (we were passing Secure), but even after updating our call to js-cookie and seeing the appropriate stringifiedAttributes in Chrome Inspector (both Secure and SameSite=None):
SameSite cookie attribute in Chrome Inspector
I am still seeing the error in the chrome console:

Operating System: OSX
Chrome version: Version 80.0.3987.149 (Official Build) (64-bit)
The issue:
I have used github project of Ofir Dagan: Storing cross domain local storage.
It implements html5 local storage:
https://github.com/ofirdagan/cross-domain-local-storage
The problem:
Safari doesn't allow third party cookies by default (other browsers allow it).
Safari privacy preferences are:
The default is: "Allow from websites I visit".
I read about these settings:
Always Block - Block all first-party cookies and block all third-party cookies.
Allow from Current Website Only - Allow all first-party cookies and block all third-party cookies.
Allow from Websites I Visit - Allow all first-party cookies and block all third-party cookies unless that third party was a first party at one time (based on current cookies and browsing history).
Always Allow - Allow all first-party cookies and allow all third-party cookies.
Solution I have tried:
Local Storage with an iframe (pixel) - I think it's no longer works on Safari - Is there any workaround to set third party cookie in Iframe for safari?
I think that there is a way to share local storage between first party and third party sites on Safari. (Facebook.com and Booking.com share data between different domains).
I succeeded to achieve it by removing the API and writing it by myself, But I don't want to remove the API and implement it by myself (hope that there is a small fix in order to support Safari):
Iframe.html:
window.addEventListener('cors_event', function(event) {
if(event.event_id === 'my_cors_message'){
if (event.data.options.funcName == "SetItem") {
localStorage.setItem(event.data.options.key, event.data.options.value);
}
else if (event.data.options.funcName == "GetItem") {
return localStorage.getItem(event.data.options.key);
}
}
});
MainPage:
<iframe id="target" src="iframe.html" frameborder="1"></iframe>
<script>
var target = document .getElementById('target');
target.onload = function(){
target.contentWindow.postMessage('set', '*')
}
</script>
So does someone know how can I achieve it by changing some API logic to support Safari?
Any help appreciated!
As noted by the Cross-Storage library documentation:
Notes on Safari 7+ (OSX, iOS)
All cross-domain local storage access is disabled by default with Safari 7+. This is a result of the "Block cookies and other website data" privacy setting being set to "From third parties and advertisers". Any cross-storage client code will not crash, however, it will only have access to a sandboxed, isolated local storage instance. As such, none of the data previously set by other origins will be accessible. If an option, one could fall back to using root cookies for those user agents, or requesting the data from a server-side store.
It seems that the recent updates to the Safari browser (Prevent cross-site tracking) blocks any cookies from being generated when the Matomo domain doesn't match the website it's being loaded from.
This breaks the use of iFrames for Matomo that require cookies to be set (For example the logme feature)
There doesn't seem to be any way to fix this with headers (Eg using CSP or CORS configurations).
current workarounds exist that I've found:
Disable the "Prevent cross-site tracking" setting in the Privacy settings
Redirect the visitor to the page outside of an iFrame to set the cookie - after this the iFrame can load as long as the CORS configuration is correct and the browser isn't completely blocking the iFrame from loading.
I'm not sure how many users are using iFrames that would require cookies to be set, but they would be impacted if any of their users use Safari.
You may try Store.JS. As per the docs:
store.js exposes a simple API for cross browser local storage
Some cookies are marked as HttpOnly. See Chrome developer tools > resources > cookies > http column, does a checkmark here indicate HttpOnly cookie?
If I use this code inside the debug console to get all cookies:
document.write(document.cookie)
Then it gives me everything except the HttpOnly cookies, which because my code is running inside the javascript environment and the design of HttpOnly is to hide it from the javascript environment.
Is there another option to use the Chrome console to get all the cookies?
I am hoping to get this in the same format as the above line of code produces.
There is a known issue where webkit browsers throw you a login popup with https sites under certain conditions. I notice it if my cookie is no longer valid.
I have an extension that accesses your Google sites but this login prompt thing is a bear to overcome. I can login to Goog's sites via perl/php and libcurl, save the needed cookies to a text file and go forward.
Can Safari extensions and XHR do the same? Can I save a cookie and its data to either memory or a variable? Can I use the cookie data in said variable in an XHR request? This would potentially overcome my problem.
I have a URI here in which a simple document.cookie query through the console is resulting in three cookies being displayed. I verified this with trivial code such as the following as well:
var cookies = document.cookie.split(';');
console.log(cookies.length);
The variable cookies does indeed come out to the number 3. Web Developer on the other hand is indicating that a grand total of 8 cookies are in use.
I'm slightly confused to believe which is inaccurate. I believe the best solution might involve just reiterating the code above without the influence of Firebug. However, I was wondering if someone might suggest a more clever alternative to decipher which tool is giving me the inaccurate information.
One reason might be that the other 5 cookies are HTTPONLY:
http://msdn.microsoft.com/en-us/library/ms533046.aspx
If the HttpOnly attribute is included
in the response header, the cookie is
still sent when the user browses to a
Web site in the valid domain. The
cookie cannot be accessed through
script in Internet Explorer 6 SP1,
even by the Web site that set the
cookie in the first place. This means
that even if a cross-site scripting
bug exists, and the user is tricked
into clicking a link that exploits
this bug, Windows Internet Explorer
does not send the cookie to a third
party. The information is safe.
Firefox also respects this flag (as of v2.0.0.5).
I'm pretty sure the web developer toolbar shows cookies for domain and sub-domains.
So it will show cookies for
abc.xyz.com
xyz.com
whether you are on a page of either domain
