IE9 Javascript injection issue - javascript

I am facing some issue with Javascript injection on IE9 (>Medium-high security). In my application when user wants to add any web page to their bookmarks, they click a link, and it injects a Javascript into that page, this injected javascript grabs all details about page and redirect users to my site.
On IE9, it does not seems to be working with Medium-high security. I suspect this has to do something how IE9 handles cross-site javascript injection. But, was not able to find any relevant information.
Can someone please help or guide me to some related information.
Thanks

You may find this TechNet post useful, especially the row "Allow scripting of Internet Explorer Web browser control".
Apparently Internet Explorer doesn't allow scripts to control the web browser except on Medium-Low and Low security levels. Because of this, you won't be able to redirect the browser unless it's set to one of those two levels.
Perhaps instead of redirecting them you could add some kind of notification to the DOM and give them a link to your website?

Single Sign On (Silent Login) using iframe and postMessage while ITP (Safari)

Short:
I need help in SSO in Safari, I'm using iFrame and postMessage logic which is working fine in Chrome and Firefox (PC, Mac, Android and iOS) but the catch is in Safari. I tried Storage Access APIs and placed those in iFrame's onLoading event to check access. But the localStorage which I was used to store JWT is not persistent in the iFrame. I'm using Angular 11.
Scenario:
I'm developing few applications which uses same auth site for sso, which was working as expected as I said in short description. But when it comes to Intelligent Tracking Prevention enabled browsers as of now Safari, It blocks the iFrame by considering it as 3rd Party Trackers which is very insane since the iFrame's origin (Domain) is same with Sub-domain used in service sites.
I tried to check the access by using storage access API i.e hasStorageAccess() in window onLoad method in the iFrame's script. If has no access, I called requestStorageAccess(). I'm here not using user gesture and using button click from service site because I'm using angular for frontend framework but in order to request using button in iFrame.(Since, The policy specifies to get access works only after user interaction which is another headache for devs)
I need help to overcome this issue and fix the SSO with ITP. Any guidance is useful and I'll keep updated.
Google is working fine with their sso and services such as YouTube and Mail doesn't need login on every visit. Any idea on how they achieved.
The reason could be that Safari has the option "Prevent cross-site tracking" enabled by default and that can interfere with the SSO login and display of an embedded iframe (because it blocks some cookies).
Solution
Disable (uncheck) the option for "Prevent cross-site tracking" in the Safari configuration menu.
Tip: To achieve a better user experience, using Javascript you can detect when a user is using Safari and show him an HTML message explaining that he needs to disable that option in order to continue or use another browser like Chrome or Firefox.

Making an iframe inherit cookies from the parent in Safari

My web app extends a Google Form's functionality by loading it as an iframe, and doing other stuff outside the iframe. If the Google Form requires authentication, Google makes a "Sign In" box appears within the iframe. When a user clicks on the button, a new tab opens, and the user is re-directed to the form in the new tab.
If a user navigates away from my web app, the extra functionality will obviously not work. So, what I am looking for is: to have an authenticated Google Form load as an iframe within my web app.
I can make the user first sign in via Google Sign-In (OAuth) on my web app and then load the iframe. On Chrome and Firefox, the iframe automatically starts with a logged-in session. This is great! But, this solution doesn't work on Safari. Is this related to Safari blocking third-party cookies?
If I want this functionality to work within Safari (and other such browsers), how would I go about doing it? Will I have to use the Storage Access API? If yes, can you broadly tell me how to do it?
For now, I could just ask users to download Firefox/Chrome if they want to use my web app. Most of my users are Chrome users anyway. But, is implementing these privacy measures a part of other browsers' roadmap too? If yes, I may as well try and build a solution that will work in a year or two.
I expect so.
This needs to happen in the iFrame, so Google rather than you need to implement it.
Yes, but not until 2022, so I would hope Google forms will support this by then.

Open Mozilla Firefox Browser using JavaScript

My Application would default start with Google Chrome. When User access one of the Menu Option , I would like to Open
That URL with Mozilla Firefox Browser. Not Google Chrome.
Can someone please help me on the same? Is this possible to Open explicit browser from JavaScript?
Thanks , Niraj Salot.
Which browser is opened is dependant on the users OS (if the browser is present, which browser is their primary etc etc), as such it's not something that can be done through a browser.
It would also be a massive security risk as if a browser could open an external application it would be open to exploits and abuses pretty much from the get go.
About the only permissiable way would be create a plug-in for Chrome which could request from the user if they would like to open the link in another browser, but then thats a alot of work for this.
You'd be better off checking what browser is being used (again since you have no control over which one the users are using) and politely ask that they open the link in firefox.

Linking users to chrome flags page

I've created a site that utilizes the new Web Midi Api, native in Chrome Canary.
Since web midi isn't enabled by default, I would like to simply direct my users to chrome://flags/#enable-web-midi where they can enable midi.
I discovered that using an anchor tag isn't allowed, nor is window.open("chrome://flags"). I'm wondering if there is a Chrome expert out there who could steer me in the right direction.
I want to make this enabling step as easy as possible for my users.
chrome.tabs.create({url: "chrome://flags#enable-web-midi"});
This does not require any permission. (This assumes you are developing a Chrome app, if you are making a normal site, then I don't think it's possible.)
Details on chrome.tabs.create.

Is there a setting in FireFox to allow the parent document access to the DOM of an IFRAME on another domain?

Notice how Firebug can access the DOM of cross domain iframes and even allow you to modify them? I'm wondering if there is an firefox addon extension or a config setting that will allow a page on our intranet to do this.
Longer explanation:
I have a two "kiosks" in our reception area that the public can use. As we're running in kiosk mode (fullscreen, no chrome), I have created a small web application consisting of a menu and an IFRAME. The menu allows users to browse to approved sites and also perform actions like printing. It also gloms onto requests for popup windows and instead overlays them in a modal iframe rather than allowing the browser and OS chrome to be exposed - breaking the "kiosk" experience.
Obviously, this works perfectly on anything internal because it's all on the same domain. It gets trickier when browsing external sites because the XSS protection kicks in and you can't see the DOM inside the IFRAME.
I have also tried using a web-based proxy server on the same domain (PHProxy for example), which works okay, but there are horrible edge cases where it doesn't work - a big one is the CAPTCHA on our website forms. So that's pretty much not an option for me.
Basically I think the only solution that will work for me is to modify the browser in some way using a security setting or an addon. Any ideas?
Thanks guys very much for you time and consideration. It is VERY much appreciated.

There is a way for unpriviledged JavaScript code (loaded from a web page) to request more privileges in Firefox. This is an old, non standard API that prompts the user for permission and if accepted allows the JavaScript to do things normal JavaScript cannot. One of these things is to bypass Same Origin Policy.
Sample code:
try {
// ask user for permission
netscape.security.PrivilegeManager.enablePrivilege('UniversalBrowserRead');
} catch (e) {
// user refused permission
alert('Permission "UniversalBrowserRead" was denied.');
}
//Should now be capable of bypassing same origin policy if user accepted
Since the kiosk browser does not restart (I suppose) very often, the dialog just has to be accepted once. Not sure this is the most elegant solution but might work, at least for now (the API is old and might disappear).
Here is a link for more details: http://www.mozilla.org/projects/security/components/signed-scripts.html#privs-list
While looking for the exact privilege name I found this page about Security Policies in Firefox. This would be a much nicer solution. I have never used it, so I cannot give more info, but here is the link, might be a good place to start looking:
http://www.mozilla.org/projects/security/components/ConfigPolicy.html
Hope this helps!
I found an addon called CrossDomain. The addon hasn't yet been updated for newer versions of Firefox. In the end, I solved this whole problem by writing an HTA and using the internet explorer rendering engine - which made my IT manager happy :). Here is the link to CrossDomain in case this helps someone one day. Thank you everyone for your submissions.

Why not use Greasemonkey, it will allow you to run your script on any page.
