Hi Emilia,

You can uninstall addons using below method.

1. Click the Customize and control menu icon on the Google Chrome toolbar and then More tools.


Navigating to More Tools

2. Select More tools from the menu.
3. Select Extensions from the side menu


4. Click the trash can icon link next to the extension you wish to remove.

The above process works well except if the extension crashes. In many cases, you won’t see it in the extension listing. It’s harder to uninstall an add-on that doesn’t show in the list. This is a trick certain malware authors use. They may also redirect you to another page.

Remove Chrome Extensions That Don’t Show

The trick to uninstalling the problem extension is twofold. First, you need to find the default folder that contains your Chrome extensions. Second, you need to find the folder containing the problem extension.

1. Close Google Chrome
2. Find your Default folder location. The location depends on your Windows operating system. You’ll need to substitute your user name where I have <username> below.
Windows XP
C:\Documents and Settings\username\Local Settings\Application Data\Google\Chrome\User Data\Default
Windows Vista – Windows 10
C:\Users\username\AppData\Local\Google\Chrome\User Data\Default

3. Within the Default folder should be another folder called Extensions. If you click that, you should see a folder for each Chrome extensions. As you can see from the screen snap below, the folder names are cryptic.

4. If you open a folder, you’ll see a subfolder with the extension’s version number.
5. If you open the folder with the version number you should be able to tell which extension it belongs. You can open the manifest.json file.

6. Open the JSON file with a text editor or code editor. I prefer the free VS Code from Microsoft, which is cross-platform.

7. If this is the problem extension, delete the folder. This will be the folder with the cryptic name. As an aside, I like this extenssion and am using it for illustration.
8. Restart Google Chrome.

Chrome Is Still Misbehaving

As I mentioned above some folks play nasty and bury their programs in ways that take more than peeking into the Extensions folder. For those cases, you might want to try a tool Google created. It’s called a Chrome Cleanup Tool and works with Windows.
According to Google, the program will scan and remove software that may cause problems with Chrome. These include:

• Pop-up ads
• New tabs that won’t go away
• Chrome homepage or search engine changed without your permission.
• Unwanted Chrome extensions or toolbars keep coming back.
• Your browser is redirected to unfamiliar pages or ads.
• Alerts about a virus or an infected device.

I hope this helps.
