I wrote a Chrome extension, that uses local storage.
When I open chrome://policy/ in the browser I can see my extension's data according to the its ID, however, when I change the value manually in the registry it DOES NOT get updated automatically. Instead I have to click on the "Reload policies" button.
My extension uses this data and has to be updated.
How can I refresh chrome policies from my code? (As if the user would click on the "Reload policies" button.)
Thanks!
For Windows, even if you're just managing the information in the registry and not via GPO, you force the updates to be reflected in Chrome with:
gpupdate /force

I would like to replace a javascript file in my Google Chrome cache such that when I reload a website it will run my modified script. I could do a whole setup with puppeteer instead but it would be just way easier if I could just replace the cached file. However, I cannot seem to locate my cache or any info on wether this is possible since the data might be encrypted or encoded. Alternatively is there an extension that would let me do this?
You can replace a JavaScript file in your Google Chrome cache by following these steps:
Open Chrome and press F12 to open the developer tools.
Go to the "Application" tab in the developer tools and select "Cache" from the left sidebar.
Find the JavaScript file you want to replace in the cache and select it.
Right-click on the selected file and choose "Delete" to remove it from the cache.
Refresh the website to reload it and run your modified script.
To run the modified script, you can use the "Sources" tab in the developer tools to open the file and paste in your changes.
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.
I used to be able to disable windows integrated authentication by updating the settings in IE. Recently this no longer works. Has something changed in recent versions of chrome? Is there a new way to turn this off?
Chrome version 46.0.2490.71
I used to use this setting in IE
Internet Options -> Advanced -> uncheck 'Enable Windows Integrated Authentication'
I got this response from an internal admin and it seems to work.
I think the best we came up with was to create a shortcut to
chrome.exe on your desktop and modify the target of the shortcut to be
something like:
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --auth-server-whitelist="_"
Edit: Corrected the path for misplaced backslashes. Note also the (x86), just in case.
Expanding on Daniel Trimble's answer, which worked for me:
I would like to help more people find this useful answer by adding a little more context. What is Integrated Windows Authentication, and why would you want to disable it?
Basically, Integrated Windows Authentication allows a browser such as Chrome to access credentials that are stored on your computer (for example, the password you use to log into your office computer) and use those same credentials to log you into a website (for example, a password-protected portion of your company's website). This occurs behind the scenes, without a visible password prompt.
The problem is that you may not want to be automatically logged into a particular website.
Example: I like to use Chrome as a test browser to see the "public" view of my company's website. Generally I log into our site in Firefox or IE, make changes there, and then view the site in Chrome to make sure my changes were "published" as intended.
Suddenly, one day, I could no longer stay signed out of my company's website in Chrome. Whenever I navigated to a password-protected page, instead of giving me a login prompt, Chrome would automatically sign me in to Microsoft SharePoint (my company's content-management system) and show me the "logged in" version of that page.
If something similar is happening to you, there are other, more obvious things you should try first. Start by clearing your saved passwords (Chrome menu button > Settings > Show advanced settings > Passwords and forms > Manage passwords).
Clearing my saved passwords didn't work for me, so I tried other things: cleared the cache, removed all cookies, reset Chrome's settings, uninstalled and reinstalled Chrome. I even visited a password-protected page in an Incognito window, but Chrome still signed me in automatically.
Finally I found this Stack Overflow page, which solved the problem. (Thank you, Daniel Trimble!) Integrated Windows Authentication was the culprit. IWA used to be turned off by default in Chrome; you had to enable it via a checkbox in your Internet Options (shared with IE). At some point in the recent past, Google apparently decided to enable IWA by default. The unfortunate part is that they did not provide an option under Chrome's Settings panel to disable it. At least there's this workaround!
How to disable Integrated Windows Authentication (IWA) for Chrome via Windows' Control Panel:
(This applies to both Internet Explorer and Chrome since Chrome uses system settings that are managed using Internet Explorer.)
Press Windows' Start button, type "Internet Options" to search, and click the one result, from the control panel
Go to the "Security" tab
Select "Local Intranet" and click on "Custom Level" button
Scroll to the "User Authentication" section at the bottom of the list and select "Prompt for user name and password"
Click Ok, Apply, and Ok to save changes
Close all instances of the IE browser to make the changes effective. Launch the browser again and access the application. A basic authentication challenge will be served.

I found out we had a windows policy that set the following registry key:
HKEY_CURRENT_USER\Software\Policies\Google\Chrome\AuthServerWhitelist
Deleting this key made Chrome prompt for a username and password for me.
More information about the registry keys.
Great and all the above answers work perfect.!
To add more -- I found that google chrome (version 68.0.3440.106) has the GUI option for Windows integrated authentication, just like in IE, this worked for me :)
goto chrome://settings/
Show advanced settings...
In the "Network" section, click on "Change proxy settings..."
Chrome opens the internet properties window
in the security tab
Select Local Intranet and Click on "Custom Level" button
Scroll to bottom of the window to User Authentication section, select "Prompt for user name and password"
Click Ok, Apply and Ok to save changes.
close existing session and start a new chrome session.
I'm looking at the offscreen-tabs experimental API here.
Then I tried to enable this but I don't see it in the chrome://flags/ part of the browser. Has it been removed from the browser as an experimental API or has it become a real API?
Yes Chrome OffScreen Tabs API was deleted from chrome extensions code base on 13 Dec 2012 as shown in this Patch / Changelist. This Chrome Issue asked to delete the specific API.
Chrome Extension Dev Page for Offline Tabs API also gives 404 that means corresponding document was also removed.

Chrome will open a new tab, and ask you to reset your settings. Click Reset.
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.
