How to remove all breakpoints in one step in Google Chrome? Using version 11.
[update]
There is now a feature request for this.
[update]
The feature request is closed (Dec 2011)!
This is now possible in Sources tab of Chrome Developer Tools.
Please see screen grab below and right click within the "Breakpoints" section of the left window.
Since recently (Chrome 18), you can right-click any breakpoint in the Breakpoints pane and voila! The "Remove All JavaScript Breakpoints" popup menu item!
Chrome Devtools crashed everytime I tried to access the Sources panel because of a breakpoint on a minified Javascript file.
To remove all breakpoints without access to the interface, you can do the following:
Open inspector-on-inspector : undock first inspector and hit ctrl+shift+i to open the second
On the inspector-on-inspector console, execute the following:
window.localStorage.breakpoints = [];
Close the inspectors and reload the page. Now the breakpoints are gone.
Under Sources, you can click button marked with red on picture below or use shortcut Ctrl + F8 just like tool tip is showing (activate / deactivate breakpoints). A little bit lower under 'Breakpoints' you will see all your breakpoints. If you choose to disable all, they will be grayed out.
solution here.
To purge all breakpoints open inspector on inspector (undock first
inspector and hit ctrl-shift-I to open the second) and run
"WebInspector.settings.domBreakpoints.set([])" in second inspector's
console.
new Tabs; Ctrl+Shift+J to Console; Access URL
Open the Chrome task manager and end the tab page.
Ctrl+Shift+J to Application -> Service Workers (Offiline) -> Refresh
to Sources Cancel Breakpoint
Success
Another option is to de-activate all break points using:
Ctrl + F8
In my case Uninstall and new installation of Chrome was without any success.
Also window.localStorage.clear() did not help.
My "last chance solution" is to remove entire directory where Chrome is storing its data.
First turn off your Chrome.
Then look at this path "c:\Users\ {your_user} \AppData\Local\Google\Chrome\User Data\Default\Local Storage\". Here try to delete all what is in this directory.
You can also clear all inspector settings and reload the inspector. It helped me with fantom breakpoint I could not remove in any other way. Open inspector and go to Preferences -> Sync -> Restore defaults and reload (at the bottom).
Step 1: Go to Developer tools and expand Breakpoint section
Step 2: Right click on expanded area of breakpint and there will be many options lik

I'm trying to view the emulation panel but I can't find it anywhere. Everywhere I've looked it says to open an overrides panel to find it but that's missing too. I also can't find any helpful or new answers to my question. Pressing esc only opens up console and there's nothing in settings that seems to help. Can someone please tell me how to reach it?
Instead of emulation in the drawer Device Mode is now offered for emulating other devices. It provides many benefits over the old emulation mode, such as taking into account the meta viewport tag on render. So what you see is much closer to what you'd get in real life.
I'm using 51.0.2704.103 (64-bit) on a Mac.
Cmd-Opt-i to open console.
Click the button with three vertical dots and the very top right of the Developer Tools window.
Select: more tools > sensors:
If the console draw is not already open it will open. Either way there should now be a sensors tab next to the console tab on the console draw. Click this tab and follow your nose from there.
Note that this tab had an x by it. Hitting this will hide the sensors tab and next time you use it you will need to follow the steps above again to reinstate it.
I have an issue with the Chrome developer tool.
My version is Version 46.0.2490.71 (64-bit)
According to online tutorials, I can go to Sources tab, right-click a script file and there will be Blackbox Script option to choose.
However, I see no option in my chrome. How do I enable that option since I have no knowledge about regex?
Another problem: The scripts still got debugged even though I added them to blackbox list. Weird!!
One more thing i want to ask is how I blackbox an "unlimited" amount of VM files?
Open devtools settings (press F1 once in devtools or open from the menu)
Go to blackboxing (see image below)
Add a pattern, for example:
node_modules
angular
rxjs
It uses regex syntax in case you need something more specific.
The nice part about blackboxing library/framework scripts is that it makes it easier to see in stacktraces from where the error was triggered in your own sources.
EDIT
As other pointed out, since this answer was posted you can directly blackbox a script with a right click on the source file in devtools.
However head off to the blackboxing settings UI for more control.
There's an easier way in Chrome 60 (and possibly older):
Open the source file in Chrome dev tools (in the source tab)
Right Click the column that displays the line numbers
Select "Blackbox Script"
EDIT: As svict4 pointed out, in Chrome 64, you can also right click anywhere on the script
It seems they changed from blackbox to Ignore List.
Also press f1 in devTools and find Ignore List
Not sure if Chrome has changed too, but on Chromium Edge, the option is named "Mark as Library Code" and "Mark as my Code" to disable it. You have to right click on the code and not on the file/tab. Right clicking on Line numbers works too.
At my new job I have to work with PhpStorm. I come from Sublime Text, and what bothers me most about PhpStorm is the lack of a single click preview of the files. In stead, it opens the files for editing and adds them to active tab, leaving me with A LOT of useless tabs.
I searched here on StackOverflow and Google, but I seem to be the only one who is annoyed by this. In Sublime it goes to edit mode only after a double click. Is there a setting or plugin to have it like in Sublime?
It's a native feature these days:
Settings... / Editor / General / Editor Tabs / Opening Policy > check "Enable preview tab"
on version PhpStorm 2022.3.2
Single Click To Open File
By default to open a file in phpstorm you have to double click it. I found this to be very annoying. Luckily you can change this to be a single click.
Steps:
Click the gear icon.
Make sure 'Autoscroll to Source' is checked
Make sure 'Autoscroll from Sourcce' is checked
http://www.ryanwright.me/cookbook/phpstorm/single-click-open-file
There is no such functionality currently available. I may only suggest to use View | Quick Definition to preview files.
Other than that: https://youtrack.jetbrains.com/issue/IDEA-130918 -- watch this ticket (star/vote/comment) to get notified on progress.
Welcome in late 2019 - we got a plugin for this now:
Plugin: https://plugins.jetbrains.com/plugin/12778-quick-file-preview
Plugin Source: https://github.com/SeeSharpSoft/intellij-file-preview
IntelliJ Issue: https://youtrack.jetbrains.com/issue/IDEA-130918
Don't forget to disable the "Autoscroll to Source" Feature, to get the full advantage of the plugin!
The closest you'll get right now is to enable 'Scroll To Source', however this will actually open the file in another tab, it will not be a preview.
Open the Project, Favorites, etc. side bar (cmd + 1 or ctrl + 1)
Click the gear in the top right
Select 'Scroll to Source'
Note 'Scroll to Source' can be enabled at the same as 'Scroll from Source', just make sure if you click on one file you wait until the sidebar catches up to click another, otherwise the sidebar will autoscroll back and forth between the two. You'll have to click one of them to break that loop.

This is now available as a native feature in the latest version: 2020.3!
See this comment on the YouTrack link someone posted above https://youtrack.jetbrains.com/issue/IDEA-130918#focus=Comments-27-4500169.0-0
Also on the 2020.3 feature list under User Experience there's a mention of "preview tab" here https://blog.jetbrains.com/idea/2020/12/intellij-idea-2020-3/
When I add mouse event breakpoint, devtools always jump into extension's JS.
Is there any way to point to my mouse event code directly?
The only way to disable the script (e.g. to avoid side-effects) is by disabling the extension (for instance, by using incognito mode if the extension is not enabled in incognito mode).
If you don't mind the scripts to run, but want to ignore extension code, then you can use the script blackboxing feature of Chrome's devtools.
If you never develop extensions and aren't interested in stepping through it, then open the settings menu of the devtools, click on Blackboxing and then the "Blackbox content scripts" checkbox:
If you only want to selectively ignore files, then you can also right-click on the source of the file that you want to ignore, and click on the "Blackbox Script" contextmenu option. To remove the pattern, go to the "Blackboxing" settings panel as shown before.
I think the simplest way is to open an incognito window (Ctrl-Shift-N) (or Cmd-Shift-N for mac) and debug in there, because then there will be no extensions loaded (by default).
I know what you mean by this question: when debugging, and doing something simple like pausing execution, you always find it breaks into one of the extension's codes instead of the current webpage's code.
open developer tools, then go to settings and then click on ignore list, and check the checkbox for add content script to ignore list, then add this to the ignore list: ^chrome-extension://
If you're using Google Chrome (or any Chromium-based browsers), simply run a new browser instance with a fresh user's data directory.
On Linux:
google-chrome --user-data-dir=$(mktemp -d)
This way, all extensions will be disabled without having to manually switch off/on them.
I like to use Profiles for that.
While changing into incognito mode might help you to disable most of the extensions, some of them might be allowed and still run. For example I have DarkReader and Ublock enabled in incognito mode.
My favorite workaround is to use a "Guest" profile or to create a profile that you can use for debugging. I think it is easier than creating a Framework Ignore List inside of devtools.
How to create a profile: https://support.google.com/chrome/answer/2364824
Example: My debugging profile
First off you should probably review the tutorial on how to debug chrome extensions here:
http://code.google.com/chrome/extensions/tut_debugging.html
When in doubt, you can always use the debugger keyword directly in the JavaScript code where you want to launch the debugger from, like so:
element.addEventListener("mouseover", function() {
debugger;
// some JS handler code...
});
Depending on if your JS is in a popup, background page, or in a content script, you will need make sure you launch the dev tools from the right place.
For a popup, you need to right click on the extension icon and "Inspect Popup" and then from the JavaScript console you would need to run location.reload(true)
For a background page, you need to go to the extensions settings page, chrome://settings/extensions, turn on developer mode, expand the extension in question and click the background page link.
The content script should be visible directly from the page it is loaded onto.
In Chrome, you can edit your resources in line and Chrome will generate revisions of that resource. Here the documentation: http://code.google.com/intl/en-US/chrome/devtools/docs/elements-styles.html#persist
Sadly, it's not working here, and I don't know how to enable it. It is not possible to expand the file in the resource tab to see the revisions.
Using Chrome 15.0.874.121 on MacOS here. A colleague of mine tried the developer channel, but it's still not there. But I saw a demo of it at the Google Developer Day.
This works in 15.0.874.121 as well -- just double-click on a text content of a CSS or JS file in the Resources panel, type something and press Cmd+Enter. You will see the lines that you added displayed with a green background, and the edited resource on the left will become expandable.
Alternatively, the Dev channel has an "Edit" button (a pencil with dots) below the resource contents if the resource is editable. You can click it to toggle the resource editing.
It works fine on ToT and on dev channel 17.0.942.0 dev.
The scenario.
open inspector's Scripts panel
start editing with double click
save the revision with Cmd+S
optional exit from editing mode Shift-Enter
open Resource Panel
click on the right arrow symbol close to edited file.
