Fix problem: Google Chrome uses a lot of processor (CPU) when I visit a website
A new trend on the internet is that of using websites to mine cryptocurrencies without the knowledge of their visitors. As a result, the visitor's web browser gets slow, and the web browsing experience becomes incredibly frustrating. If you use Google Chrome and your computer's processor usage goes up a lot, when visiting a specific website, then you must read this article. We explain why this issue occurs and what you need to do, to protect yourself:
The problem: The CPU usage of Google Chrome goes up when I visit a particular website
In the last few months, many users complained about this problem: when you try to visit a specific site, the processor (CPU) usage of Google Chrome shoots up to a large percentage like 45%, 75%, 90% or more. The computer or laptop being used gets louder because the ventilation kicks in to cool the processor. This also leads to increased power consumption.
When you close the tab with that website, everything goes back to normal. This recently happened to us too, on a website or two. Below, you can see the CPU usage of Google Chrome, with only one tab open and one website loaded.
This is a lot if you ask us, especially when using a powerful desktop computer, with plenty of CPU power.
Why does this happen? Because of cryptocurrency mining!
It is not moral, but there are no laws against this practice, yet.
How to fix the problem: Install No Coin for Google Chrome
No Coin is an open-source project that was created by Rafael Keramidas. It blocks cryptocurrency mining automatically so that you are protected from this practice when browsing the web. Opera has this tool built-in, while Google Chrome has a No Coin extension that anyone can install. In Google Chrome, go here, and then click or tap "Add to Chrome."
Confirm that you want to add this extension to your browser by clicking "Add extension."
You are informed that No Coin was added to Google Chrome, and you can see its icon near the address bar on the top. You can see it highlighted in the screenshot below.
When this icon is displayed in Google Chrome, you are protected from cryptocurrency mining, because this extension automatically blocks the scripts and the ads that are used for this practice.
Does No Coin work, for real?
To make a quick test, we visited the same website that does cryptocurrency mining, after No Coin was added to Google Chrome. You can see, that the processor usage decreased from 45% (in the first screenshot) to 3% (the screenshot below). That is a considerable improvement that leads to an excellent user experience.
