It has ‘Workspace’ section. 2) in this section you need to click on ‘Add folder’ item. It will show folder selection dialog. 3) After selecting a folder you will see an info … Read more
If you detach the Dev Tools (icon next to x in the top right corner) in a separate window, and press Ctrl+Shift+I while Dev Tools window is focused, you will invoke the Dev Tools for the Dev Tools window. As far as I am aware, it’s not possible for a docked configuration.
Click Network, WS, select the original HTTP connection and then click the Frames tab. Be aware that the content of this tab may be hidden by another pane, so you need to drag the bar down to see the WebSocket frames.
This worked for me: Go to Inspect → Settings (Symbol) gear → Uncheck Enable JavaScript source maps and Enable CSS source map. Refresh. (Note: Deactivate Adblock if the above process did not work.)

As mentioned in a comment before: In Chrome, red dots usually represent non-printable special unicode characters. Please check your server side code to prevent outputting those characters

Some browsers may have some of this info available to browser extensions as part of their developer tools support, but that would require the installation of a custom extension, not something that could be done … Read more
You may be looking for the “Event Listener Breakpoints” section on the right side of the Debugger area. Open that up and select the click event under “mouse”. See the screen image. Then click on the button in the app and you will immediately be taken to the code being executed.
If the hover element is triggered by JS (if triggered by CSS :hover, see gmo’s answer), you can inspect it if you pause script execution. This is a much simpler way of freezing the DOM than the other answers suggest. You can pause script execution without losing the hover element as follows: 1. Via a … Read more
