In an effort to prevent malicious sites from using your computer’s processing power to mine cryptocurrency without your knowledge, Google is blocking all extensions that include mining scripts in the Chrome Web Store.

Google says it previously allowed extensions that mined currency, as long as they were designed specifically for the purpose and explicitly stated their intended use. However, since it’s found that about 90 percent of extensions that include mining scripts don’t follow its rules, it’s banning mining extensions entirely.

Mining can negatively impact system performance as it takes up significant CPU power to run the rigorous calculations needed to mine the digital tokens. Companies and hackers have also been known to plant backdoor coin mining scripts in public websites to appropriate computational power from unsuspecting browsers.

Google’s extensions platform product manager James Wagner said:

“The extensions platform provides powerful capabilities that have enabled our developer community to build a vibrant catalog of extensions that help users get the most out of Chrome. Unfortunately, these same capabilities have attracted malicious software developers who attempt to abuse the platform at the expense of users.”

Wrapping up:
Therefore, this policy, the company said, aims to ensure that Chrome users can enjoy the benefits of extensions without exposing themselves to hidden risks.

On a related note, existing extensions that mine cryptocurrency will be de-listed from the Chrome Web Store in late June.
