Extensions are helpful additions that you can use to make Google Chrome better. Every Google Chrome user can extend Chrome with useful extensions.

However, extensions can also make Google Chrome slower or stop working altogether. In addition, there are also a lot of malicious extensions available for Google Chrome. Unwanted extensions can then in turn, modify the Google Chrome home page or change the search engine undesirably.

So in some cases, you may not want to add new extensions to Google Chrome. Blocking Google Chrome extensions then offers a solution. In this article, I will explain to you step by step how to prevent Google Chrome extensions from being installed.
