Google has decided to prohibit the placement of extensions, aimed at cryptocurrency mining, in the Chrome Web Store. As stated in the official blog of the browser, the decision was made in order to protect users from crypto-jacking.

The ban entered into force on 2 April. All store-built extensions will be removed by the end of June 2018.

“Until now, Chrome Web Store policy has permitted cryptocurrency mining in extensions as long as it is the extension’s single purpose, and the user is adequately informed about the mining behavior. Unfortunately, approximately 90% of all extensions with mining scripts that developers have attempted to upload to Chrome Web Store have failed to comply with these policies, and have been either rejected or removed from the store,” James Wagner, Extensions Platform Product Manager of Google, said.

At the same time, the message states that the ban will not affect other extensions related to the blockchain technology and cryptocurrencies.

Earlier, Google announced that it changes its advertising rules and will prohibit advertising of cryptocurrencies and ICO starting from June. As stated in the company's official blog, it will become part of company's efforts to counteract unregulated and often fraudulent financial products. Similar measures in January were taken by Facebook. The Facebook's ban will affect ads of crypto-exchanges, wallets, binary options and other high-risk financial instruments, as well as trading advice.
