I have 2 chrome profiles. My aim is to control these 2 windows using puppeteer. So first, I have to open these profile windows via command line, specifying the debugging ports.
command 1: google-chrome --remote-debugging-port=9222 --profile-directory="Default"
command 2: google-chrome --remote-debugging-port=9223 --profile-directory="Profile 1"
When 1st command is executed, it opens a chrome window with the profile I mentioned. And I also get a WS URL for that browser. So I can use that in puppeteer.
Problem is while running second command. It also opens the profile, but no URL. It says "Opening in existing browser session".
I want to open more profiles and control them with puppeteer. Please help.

The Network tab in the Google Chrome Developer Tools window shows almost all http requests made, but does not seem to capture anything when the http request results in a file being downloaded.
How can I capture download requests in Google Chrome?
I am sure that your file download is happening by opening a new window. Network tab of developer tools only captures the request of current tab.
For example, following link will download the file but it will not appear in the network tab.
Click Here to Download file
Similar type of things can be done using javascript using (window.open, dynamic hyperlink/iframe), which will not appear in the network tab.
Various Javascript approach you can check here
I have observed similar behaviour in my past.
You cane check the chrome://net-internals in older version of chrome and chrome://net-export/ in the newer version of chrome to monitor any type of request being made by any instance/tab of chrome.
Note: You can check the internal events of chrome by typing chrome://net-export/ in the url box of chrome.
I have faced similar issue, and here's how I solved it.
Issue:
Debug an anchor link that download file upon clicking it.
Debugging Process:
Steps
Go to chrome://settings/content/automaticDownloads?search=download and disable auto download
Open chrome dev tools, Settings -> Global -> Auto-open DevTools for popup
Open chrome dev tools, Settings -> Console -> Preserve log upon navigation
I hope that helps.
This works without changing any settings of Chrome for a single download-request. It however does not automatically display all download-requests triggered in a different tab or window.
Trigger the download in the GUI.
Open Chrome's download history (chrome://downloads/).
Right-click your download and Copy link address.
Open DevTools, paste the link into the address bar of the corresopnding Chrome tab and execute it.
The download-request shows in the DevTools.
You can use Fiddler for a more grainy look into your network traffic:

*I don't work for fiddler
What do you mean by capture?
If you meant that nothing showed up in preview tab or in response tab, it's because the response is the actual file being downloaded.
I've recently tried downloading Oracle JDK 11 with dev-tools open in network tab and here is what I got:
I have no particular configuration in this version of Chrome (Versione 71.0.3578.98 (Build ufficiale) (a 64 bit))
As #jlvaquero said, if you're trying to get as much details as possibile, try WireShark on your own local pc.
I can see it in my case by downloading a document from google drive and limit download speed to 3G.
First step : Open with f12 the programmer toolbar.
Step Two : Go to the networking tab and locate the video in question. To help filter by clicking on media.
Step Three : If the video has no protection you can right click, click open on a new tab and download with crtl + s. If this does not work is because the video has parameters to prevent it from doing so. In that case right click again, go to the COPY session and then click copy as cURL.
Step Four : Go to your linux terminal (If you use windows turn around), if you don't have curl installed type sudo apt install curl and then paste the copied CURL command from the developer bar.
Step 5 : Before executing the command you need to add at the end of it --output video.mp4 --insecure as it is a binary. The insecure parameter is if you have problem with certificate. Wait for the download to complete and be happy!

Google Chrome has been updated to support downloads in the Network Tab
This question was asked in February of 2018, and at the time Google Chrome did not support downloads in the Network tab.
I have verified this by downloading the 64.0.3282.140 build of Google Chrome.
And then attempted to download Spotify as an example and found no event appear in the network tab.
Any Google Chrome version released in 2019 or later will capture all download requests in the Network tab.
I want to open chrome://inspect from windows command prompt.
Here my use case is I want to open the chrome browser from command prompt(using ProcessBuilder in java) and chrome://inspect link so i can see the devices attached to my system
so i tried opening chrome://inspect using this command
start chrome chrome://inspect which is not working
if I replace chrome://inspect with any url it's working.
Can any one let me know how to do this from command prompt or any other possible ways to do this
Chrome URLs can't be opened from the command line. They must be typed by a user into the omnibar.
I am making a batch file that opens chrome to a specific page. I started with the
start
command by writing the line:
start http://www.google.com
I then added the specific browser chrome to open the tab.
start chrome.exe http://www.google.com
However i noticed that google chrome has an "account feature" that lets you browse as different accounts. I tested everything i could guess but i can find a way to get chrome to open the tab as a specific user.
You can use chrome.exe --profile-directory="Profile 1" to start chrome under a specific Chrome user.
Take a look at this article over on Superuser: Resolved Superuser question
There was a very interesting response over there about how Chrome has a neat feature of adding desktop shortcuts for specific users in the Chrome User settings.
