High CPU usage by an extension, but which extension?

[fencegeek55]

Description of the issue:

Brave browser has suddenly started using over 30% CPU.

I have narrowed down the source to an extension, as I see in the Task Manager of the Brave browser. However, the task does not clearly name the extension. Rather, it shows as a Service Worker of the extension. How do I identify the extension name?

How can this issue be reproduced?

You will need to have the same extension installed.
I have attached a screenshot of Brave’s Task Manager showing the Service Worker consuming high CPU usage.

Expected result:

Once the extension is removed, the high CPU usage should go away.

Brave Version( check About Brave):

Brave is up to date

Version 1.76.74 Chromium: 134.0.6998.89 (Official Build) (64-bit)

I figured it out. I clicked on the burger icon at the top right of the Brave window, selected Extensions, and then Manage Extensions. You will see all the extensions you have installed. Next, toggle the switch on for Developer mode. Now, the service worker IDs get displayed for every extension you have installed.

I hope this helps others.

Searching for that extension string seen in the service worker will tell which extension is which also
