To remove offline extensions from Chrome, you need to follow these steps:
1. Open Google Chrome browser and click on the three dots at the top right corner
2. Click on More tools and select Extensions from the drop-down menu
3. Look for the extension that you want to remove and click on the Remove button
4. If the extension is grayed out and says "Installed by enterprise policy," then it means you cannot remove it. This usually happens if your computer is managed by an IT administrator, and the extension is pushed by a policy.
5. Once you click on the Remove button, you’ll get a pop-up asking for your confirmation. Click on Remove to uninstall the extension from Chrome.
Note: If you want to install or remove extensions that require a restart of the browser, make sure to close and reopen the browser after installation or removal.
