How to disable JavaScript in Chrome Developer Tools?

I am trying to debug the features of a website when users disable their JavaScript. I was wondering how do you disable JavaScript for a page from the Google Chrome DevTools?

The command menu, which has been around since about April 2016, is probably faster than the older workflows that relied on going into DevTools settings: https://mcmap.net/q/73797/-how-to-disable-javascript-in-chrome-developer-tools – Clutch 21/11, 2016 at 18:51

I am adding this as a comment because it does not answer the OP question, but it answers a related question that I was looking for (I found this, but not an answer to my question). If you want to turn off only a specific script, for example a slide show, because it is impeding efforts of adjusting CSS styles in Dev tools, do the following: Go Sources tab. Navigate file tree to find the script (usually you want to choose the minimized version). Click the || pause button. Now you can go back to the Elements tab to inspect/edit CSS without HTML (& scroll location) constantly changing. – Amanuensis 18/9, 2021 at 21:13

Click the gear icon in the corner of the Developer Tools, click Settings, then under Debugger, check Disable Javascript, as shown in the following video:

It is not working for me too. @Matt did you find a solution? I am trying to avoid a page from auto reloading using javascript and chrome developer tools disable JavaScript is not working. – Preeminence 25/4, 2013 at 16:27

@Krishna: It's probably auto-reloading without Javascript. – Brashear 25/4, 2013 at 17:13

Yes. Looked at the source and was meaning to update it here a few hours back, but got held up. It is using meta refresh. – Preeminence 25/4, 2013 at 20:33

If still not working, consider Ctrl+Shift+n, Open new Chrome window in incognito mode. – Hamhung 22/9, 2014 at 2:14

@PaintyJoy, thanks for that tip. For some reason my "Disable Javascript" is being buggy when I refresh... "Incognito Mode" -> F12 > Settings > "Disable Javascript" -> Refresh works! Would love to know WHY it's not working in regular mode. I haven't found any tickets for this issue. Seems to only happen to certain users. – Multifaceted 29/10, 2014 at 19:16

@MattParkins Chrome Developer Tool seem to break every now and then ("complex" code I guess ^^). So use Alex's answer isntead https://mcmap.net/q/73797/-how-to-disable-javascript-in-chrome-developer-tools – Flummox 5/12, 2014 at 13:48

I know this is an older post, but it was the only thing that helped me with a google search of google chrome 45.0.2454.85 incognito disable javascript .. and I had to do it through DDG at that .. just wanted to note that as of a fresh install of Chrome 45.0.2454.85 the 'gear icon' does not show anywhere on the screen (in regular or incognito mode) and I had to hit F12 to get the to icon .. FYI to others that might have the same issue – Perdu 11/9, 2015 at 23:2

@txtechhelp: The question is specifically asking how to disable Javascript from the dev tools. Clarified. – Brashear 13/9, 2015 at 1:21

Can you please add a screenshot that shows the location of the "gear" icon in the lower-right corner of the Developer Tools? For example, here is a screenshot of the Developer Tools that shows there is no "gear" icon. – Threedecker 29/12, 2015 at 15:39

There is no gear icon anymore, they removed it at some point. – Matter 14/3, 2016 at 12:32

@ShadowWizard: Click the ... menu in the corner, then Settings. – Brashear 14/3, 2016 at 13:54

Yeah, they moved the cheese around. Found it in a newer answer. :) – Matter 14/3, 2016 at 14:25

You will now find the "Disable JavaScript" option on the right side in de Preferences menu. Headline is: "Debugger" – Carouse 19/10, 2016 at 11:37

It doesn't always work. I can't stop the javascript of Chrome Extensions even if I disable it both on the page and on the extension inspect view. – Khano 6/6, 2018 at 16:10

Update August 2020

Developer Tools (F12)
Click the Gear icon

Should open the Preference tab
Disable Javascript option is on the far right

Original answer

Developer Tools (F12)
Three vertical dots in upper right
Settings
Under the "Preferences" tab on the left

There will be a "Debugger" section with the option (probably on far right)

Correct, they made it heck lots harder to find, no idea why. – Matter 14/3, 2016 at 12:32

Maybe it's less important now so many web apps require JavaScript? It's so frustrating because I have to keep testing graceful degradation so I need to continually switch back and forth. – Mustache 3/11, 2018 at 16:0

Official documentation: Disable JavaScript With Chrome DevTools

There's now a command menu built into DevTools that makes it easier to disable JavaScript. This has been around as of April 2016 or so.

Open DevTools.
Press Command+Shift+P (Mac) or Control+Shift+P (Windows, Linux) to open the Command Menu. Make sure that your cursor's focus is on the DevTools window, not your browser viewport.
Type Disable JavaScript (or some version of that... it's a fuzzy search) and then press Enter.

Use the Enable JavaScript command when you want to turn it back on.

This extension makes it faster (I am the author) : Quick Javascript Switcher

It is open source: https://github.com/maximelebreton/quick-javascript-switcher

Great tip, works superduperly — quick and simple and reloads the page too! Instant on and offness – Tojo 27/4, 2013 at 10:28

Bad thing is that it reloads the page, while I need it not to do so. – Lisk 15/5, 2017 at 7:9

@Lisk it appears to have been addressed, there is now a Auto-Refresh option. Maxime, it would be good to say in the answer that you are the author. The only big missing thing is a shortcut or documentation for it: github.com/maximelebreton/quick-javascript-switcher/issues/32 – Cloudy 24/5, 2021 at 14:10

Thanks @CiroSantilli新疆棉花TRUMPBANBAD, this is fixed. – Retroact 26/5, 2021 at 18:8

You can also run Chrome with JavaScript disabled by default by using the flag:

-disable-javascript

You would use this for example by running Chrome like this:

C:\Documents and Settings\%username%\Local Settings\Application Data\Google\Chrome" -disable-javascript

-disable-javascript doesn't work with google-chrome-stable-51.0.2704.106-1.x86_64. – Mozellemozes 16/7, 2016 at 20:44

Try --blink-settings=scriptEnabled=false instead – Negrillo 24/4, 2018 at 7:48

On OSX, I had to click the triple vertical dots, and uncheck a box in the settings section. Which can also be opened with f1

Using only the keyboard at least for Windows 10:

F12, shows Developer Tools
F1, shows Settings
tab, moves to the "Disable Javascript" check box
space, toggles the option
esc, hides Settings

On Mac OS X:

Preferences
Show advanced settings
Press the "content settings" button
Scroll to the "JavaScript" section
Check the checkbox in front of "Do not allow any site to run JavaScript"

The Chrome Quick JavaScript Switcher extension is a lot easier though :-)

Go to options (Windows: three vertical dots in the top right) -> Settings, or hit F1.
In the General section you find "disable JavaScript"

The gear icon is no longer part of developer tools. Since Chome 30.0 it is not even possible to bring it back (In Google Chrome Developer Tools, the toolbar icons disappeared. What gives?)

Full and fast instructions for Chrome browsers (Opera incl.)

The first way

If Developer Tools aren't open then press F12 key on keyboard to show the Developer Tools. In Opera browser you have to use key combination Ctrl + Shift + i on keyboard to open it.
To show the settings just press F1 key on keyboard. The Developer Tools window must be focused when you are doing it. Or if you want to open the settings with the mouse then you have to click on ⋮ button in the top right corner of the Developer Tools, then click Settings in the menu.

Then you have to scroll down the settings window to bottom and then you will see the checkbox for disabling JavaScript like follows:

Just click on this checkbox and push esc key on keyboard for hide the settings. If you want to enable it then you have to do the same way again.

The second way

If Developer Tools aren't open then open it like in the first way is described.
Press the key combination Ctrl + Shift + P (for Windows or Linux) or Cmd (⌘) + Shift + P (for Mac) to open the Command Menu. Be sure that the focus is on the DevTools window.
Type there "Disable JavaScript" and then press Enter or click it with the mouse. If you want to turn back the enanled JS then open the Command Menu again and type there "Enable JavaScript" and then press Enter or click it with the mouse. You could also write just only "JavaScript" or "Java" there and then choose it with the mouse.

If all this does not work

For some reason it is possible that it does not work. I this case open a new empty site in "Incognito Mode" and do all this there.

The quickest way

In Chrome Web Store or on Opera Addon site you can find and install extensions which do it per one click. Just search "Javascript Switcher":

Press F8 for temporarily freezing / unfreezing JS (with DevTools open).

This is very useful for debugging UI issues on elements that may lose focus if you click or press anything outside of that element. (Chrome 71.0.3578.98, Ubuntu 18.10)

Paste it: chrome://settings/content

Go to "Javascript" section and disable it.

Fratricide answered 1/3, 2018 at 14:8 Comment(1)

Could you provide more detail? The user has to go down to the JavaScript section and choose "Block". – Hawn 1/3, 2018 at 14:38

Chrome://chrome/settings/Privacy/Content settings/JavaScript

and there you can PASTE your website's URL in Manage exceptions.. and change the JavaScript priority from ALLOW to BLOCK.

alt + cmd + i, this open dev tools, unless you use pocket, that need set other shortcut.
shift + cmd + p, then input: javascript

There's a settings in chrome

open the menu from chrome, click settings > type in "javascript" in the search bar > click site settings > click javascript.

from here you can toggle javascript specifically to a site using their url. or just click the big button to allow/block it to all sites.
