412 How to remove bad extensions in Chrome

Print Friendly, PDF & Email

Like most of the computer users around the world, I use Google Chrome as my default web browser. And I use a few extensions. But not all extensions are good – here’s how to check it and remove the ones you don’t want.

Google Chrome


An extension is just a little piece of software that runs inside Chrome to perform some specific task.

One example of an extension that I install on all of my client computers is the uBlock Origin extension. It’s an ad blocker. so that when you use Chrome to visit a website, it prevents the ads from being displayed.

There are thousands of extensions that perform little tasks like that, and in general they make using Chrome and browsing the internet more efficient.

But sometimes there are malicious extensions that can get into Chrome. These are not viruses, but they are annoying. They might change your default search engine from Google to Yahoo or something else. They might even change your default browser from Chrome to some other browser. Or in some really bad cases, they might just run in the background mining cryptocurrency – this means that the creator of that extension is making money, and they’re using your computer’s processing power to do it, around the clock. And this means your computer would probably run much more slowly.

So it makes sense that you would want to check and see what extensions are installed in Chrome, and get rid of the ones you don’t use or want. Here’s how you do that.

Open Chrome, and click the 3 dots in the top right corner. Then go down to “More tools” and in the new menu click on “Extensions”:

That will take you to a screen that will show all of the extensions that are currently installed in Chrome. They are displayed like this:

For each one, you have the option to turn it off (by sliding the switch to the left), or click the “Remove” link to get rid of it completely. If you see extensions that you know you don’t use, just remove them. If you’re not sure about one of them,  you can turn it off and see if it affects anything you do in Chrome. If needed, you can go back in and turn it back on.

I recommend only having extensions installed that you are actively using. Too many extensions will slow Chrome down. I had one client who couldn’t understand why Chrome was so slow – and when I checked, there were 80 extensions installed. And the client had no idea how any of them got there!

To keep Chrome running efficiently, get rid of those unwanted extensions!

Very helpful reminder! I removed several extensions that I never use and completely forgot.

There is also a helpful “update” button which, obviously, will update your exensions.
