Here’s a helpful video I created for toggling JavaScript on or off in Chrome. It’s especially useful for debugging or increasing security in specific situations:

JavaScript is responsible for most of the interactivity on the web — think dropdown menus, form submissions, dynamic ads, and interactive charts. Most of the time, you want it enabled. But occasionally, disabling it can help with troubleshooting or speed.

In the video, I guide you through the steps:

  1. Open Chrome and go to:

arduino

CopyEdit

chrome://settings/content/javascript

  1. You’ll see the default setting is “Allowed.” You can toggle it to “Blocked.”

You can also create exceptions, allowing or blocking JavaScript only for specific sites. This is great if you want tighter control — for example, keeping JavaScript disabled on unknown sites but enabled for trusted platforms like Gmail or YouTube.

One note: disabling JavaScript breaks a lot of sites. Pages may not load correctly, buttons won’t work, and content could be missing. I show a couple of real examples in the video so you know what to expect.

I’ve used this feature during troubleshooting sessions or when trying to isolate issues on page load.

Do you usually leave JavaScript on or tweak it depending on your tasks?
