How to apply and then remove after installation) Speed ​​Dial 3 extension for Google Chrome?

Question

Google Chrome

The GOOGLE CHROME shortcut page is small. There are extensions that eliminate this shortcoming, for example Speed ​​Dial 3, but after installing it, something went wrong, but I could not remove the extension. I had to remove all Google updates to the original version and update to the latest. I clarify the questions:
- Is the extension adapted for mobile devices (tablet)?
- How to remove the extension because it is not an application, but a system chrome, it cannot be removed along with the extension
