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

Question

I'm trying to do a simple test without changing any server-side code involving a cross-domain AJAX call, and I was wondering if it's possible to use --disable-web-security anymore. It seems to not work on Chrome 28.

I haven't used it since Chrome version 21; has this feature been dropped?

Solution 1

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

Solution 2

The new tag for recent Chrome and Chromium browsers is :

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

Solution 3

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!

Solution 4

This flag worked for me at v30.0.1599.101 m

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

Solution 5

This should work. You may save the following in a batch file:

TASKKILL /F /IM chrome.exe
start chrome.exe --args --disable-web-security
pause

That's from 2011 and also discusses Chrome 21-23. Their solution of killing all processes didn't work; I tried before posting. A workaround would be to download a very old version of Chrome, but I'm wondering if it's still a feature in Chrome 28.

[Fields]

That did it. I just forgot to kill one chrome process.

Says invalid agrument start

Please try this in a file batch (I should have introduced a new line before start): TASKKILL /F /IM chrome.exe start chrome.exe --args --disable-web-security pause

[Zahran]

I am not sure why stackoverflow does not allow me to introduce new line. The above script must have a new line before start and before pause.

[Mukus]

I did it in a batch file. No worries though. I can open up task manager and kill the process tree for chrome

[Phylogenesis]

A little late, but I've edited your answer as you wanted.

This is working, using only --disable-web-security doesn't.

[GrandmasterB]

On the second param, be sure to specify a path, like --user-data-dir=c:\my\data

[Cripto]

So the warning stating "unsupported command" can be ignored? It's being supported?

[a.barbieri]

let's say I want to enable web security again. How can I do it?

[inf3rno]

With the current Chrome it doesn't matter. I am browsing with enabled security while e2e testing with disabled security in a different window using Karma...

Mac one does not work. Almost tried everything after first trying the above one. --disable-site-isolation-trials -> does not work --disable-gpu -> does not work Tried opera also -> no luck

The user-data-dir flag is now mandatory when trying to disable web security, because it effectively launches a second Chrome "profile". You can run a normal ("with" web security) profile by just launching Chrome with no command line flags, and this "good" session can run at the same time as the unprotected session.

[Coderer]

In case anybody finds this in 2020 and beyond: this is no longer valid. disable-web-security now has no effect if you don't also specify user-data-dir -- you can't disable web security on your default profile.

add a " in front for the is not a recognized command error

[kay]

Anno 2020, as of Chrome 86, yes it works. The message can be ignored.

Mac command works for me on Big Sur. Not sure if it's a factor, but Chrome was not running when I entered the command. For what it's worth: Chrome then acted as if it were being installed for the first time.
