Does --disable-web-security Work In Chrome Anymore?

This flag worked for me at v30.0.1599.101 m enter image description here

The warning "You are using an unsupported command-line flag" can be ignored. The flag still works (as of Chrome v86).

Check your windows task manager and make sure you kill all chrome processes before running the command.

The new tag for recent Chrome and Chromium browsers is :

--disable-web-security --user-data-dir=c:\my\data

Try this :

Windows:

Run below commands in CMD to start a new instance of chrome browser with disabled security

Go to Chrome folder:

cd C:\Program Files (x86)\Google\Chrome\Application

Run below command:

chrome.exe --disable-web-security --user-data-dir=c:\my-chrome-data\data

MAC OS:

Run this command in terminal:

open -n -a /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --args --user-data-dir="/tmp/chrome_dev_sess_1" --disable-web-security

Hope this will help both Windows & Mac users!
