I'm building a custom context menu in vanilla Javascript for a web app. Using the current version of Safari (15.5) on Monterey 12.4, it works just as it should when the user right clicks (i.e. clicks using the right side of Magic Mouse), but does something different when the user holds down the control key and left clicks. The puzzle is that it seems that these two actions should be identical in their effect. (I think that one difference is that control-click generates a contextmenu event and a click event).
In contrast, Chrome (v101.0.4951.64) just produces a contextmenu event for a control-click, the same as for a right click.
I have 'Secondary click' ticked in System Preferences > Mouse > Point & Click.
Is this a bug in Safari, or something weird about my system? Any suggestions for how to work around this (just ignoring the extra click won't work, because left click on the element is used for another function)?
While debugging a web page in Chrome, my finger slipped and I pressed a combination of something (around the F12 key) on the keyboard. I got this screen:
Which is incredibly handy for developing mobile pages and actually something I've been looking for. Now I can't figure out how I got this.
So, how do I get back to this screen.
That's the emulation screen, press F12 then click on the mobile in the top left corner.
Simple, press F12 to open up the developer console.
Then, to show the device choice options:
Ctrl + Shift + M in Windows/Linux
Cmd + Shift + M in Mac
To show the ruler, go to:
Under Settings > General > Show rulers a ruler can be enabled which
will be displayed when you hover over or select an element in the
Elements panel.
All keyboard shortcuts for Chrome can be found here:

I think this question is going to be rare, hence enjoyable for some. I have two products - Salesforce's Developer Console & Google Chrome.
Google Chrome has built in hotkey - ctrl + page up/down to switch tab.
Unfortunately Salesforce's Developer Console uses the same hotkey to switch between tabs within console.
Now I will contact Salesforce support and maybe 3-6 months later they will fix the problem. I suppose contacting Google for support is ...
I have tried Shortcut Manager extension for Chrome but it does not have the option to disable the mentioned hotkey.
I was thinking wether it would be possible to overwrite the integer value in keyCode in Salesforce's script?
I've read somewhere that browser Extensions do not have such access. Not sure whether that is true, but then perhaps something like Privoxy could work?
Thank you all.
To enable and customize keyboard shortcuts:
From Setup, click Create | Apps.
Click Edit next to a Salesforce console app.
Click Customize keyboard shortcuts.
Click Edit on the top of the page.
Select Enable keyboard shortcuts.
Edit an existing keyboard shortcut or create a new one:
To edit a shortcut, click Edit next to the shortcut, type the combination of key commands to use, and click OK.
To create a shortcut, click +Add Keyboard Shortcut, type the action the shortcut will perform, a Console Event Name, which is a unique identifier, the combination of key commands to use, and click OK. For the new shortcut to work, you must send the Console Event Name to the developer who defined your shortcut’s action so that he or she can add it to the method that will trigger your shortcut.
To deactivate a shortcut, deselect Active next to the shortcut’s name. You can’t delete the default shortcuts provided by Salesforce, but you can edit or deactivate them.
Click Save.

I need to access Safari Menu options to reset browser settings. How to achieve this using Javascript.
Manual Actions are as follows
ALT + E + E
click Tab (10 times)
Click on Enter button
I'm afraid Safari isn't going to provide such API for JS at least for security reasons. I think it may be possible in Safari extensions.
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?
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:
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)
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.
chrome://settings/content Javascript/Manage Exceptions
This extension makes it faster (I am the author) : Quick Javascript Switcher
It is open source: https://github.com/maximelebreton/quick-javascript-switcher
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
The quickest way is problably this one:
F12 to open the dev console
ctrl + shift + p to open the command tool (windows)
Type 'disable javascript' and hit enter
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
The fast way:
1) just click on CTRL + SHIFT + P
2) fill the field by the 3 letters dis and will appear this box and select the item Disable Javascript
.
that's all folks!
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?)
To temporarily block JavaScript on a domain :
Click on the Button left to the address on the address bar (which says View site information)
In the drop-down next to JavaScript, select Always block on this site
Reload Page
Click the ⋮ menu in the corner of the Developer Tools, click Settings
Click on Advanced at the bottom
Click on Content Settings
Click on JavaScript
Switch off
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":
For Chrome browser
For Opera browser
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.
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.
This is the latest setting for the windows
Settings > Advanced > Privacy and security > Site Settings > Javascript > Blocked then get switch on and off
good question, i try so many way, but it is curry and boring, until i find shortcut.
alt + cmd + i, this open dev tools, unless you use pocket, that need set other shortcut.
shift + cmd + p, then input: javascript
only two shortcut, but i think safari is more convenient for that.
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.
I arrived here simply wanting to know how to disable javascript in chrome:
Right click on the website
Click "inspect"
Hit keys: ctrl + shift + p
Type: "Java"
Click "disable JavaScript"
Refresh page
It's from here
