When you select the option Help > Toggle Developer Tools, the Chrome DevTools window should open. Visual Studio Code is built with Electron, which is simply put a wrapper or container for creating desktop applications built with HTML and Javascript.
With this in mind, the Developer Tools can be especially handy if you're debugging or developing plugins, or IDE specifics for Visual Studio Code itself.

In mycase, can not find in Toggle Developer Tools from Help, but find CommandPalette(Cmd+P and type '>').

Hello, i recently discovered that you can open site in vs code using built in simple browser. But I can't open inspect tool in it to visualize paddings and margins. Is there a way to add this function, or through some extension? It would be much nicer not having to switch between ide and browser all the time
I also had to downgrade the Jupyter extension to version 2025.6 instead of 2025.7. I have VS Code version 1.103.2 on macOS. After that, the list of Python Environments was loading correctly.
For example I have "Extension" named Python in the image below that gets updated or installed by vsCode automatically
- You have to wait for the "Extensions" to be installed.
- Make sure you have an internet connection.
- make sure you have a fast internet connection so that it can be installed faster.
- After installation restart "vsCode"
If it doesn't work for you, try uninstalling the extension and reinstalling it
This is all I know and it happened to me
Hey everyone,
I'm running into a persistent issue with the Jupyter extension in VS Code and I'm hoping someone can point me in the right direction.
I'm trying to run a simple Python cell in a .ipynb notebook, but I can't execute anything because the Jupyter extension fails to start. As you can see in the screenshot, I keep getting the error notification: Extension activation failed, run the 'Developer: Toggle Developer Tools' command for more information.
What I've Tried So Far:
-
Reinstalling: I have completely uninstalled and reinstalled the Jupyter extension (and its related dependencies like the Python extension) multiple times.
-
Restarts: I have closed and reopened VS Code, and even restarted my computer.
-
New Environments: I've created fresh virtual environments (using
venv) and installedipykernelwithin them, but the issue persists no matter which interpreter I select. -
Different Files: This happens with any notebook file, even a brand new one with a single
print()statement.
I feel like I'm missing something obvious, but I can't figure out what
