How to block cryptocurrency miners in your web browser

Cryptocurrency mining has been the rage ever since 2017 and people have been trying to increase their mining efficiency ever since by spending thousands of dollars on equipment that can perform these calculations faster and more efficiently.

Mining refers to the act of performing calculations that add a new block of information to the blockchain network, which results in the miner rewarded with a certain amount of cryptocurrency that their calculation deserves.

Cryptocurrency miners usually use gaming equipment because these can provide high enough power for them to make a profit over a certain period.

Although your efficiency might not be high, the amount of resources that you can generate is undoubtedly far more significant than you would imagine.

The problem mentioned above can be solved by installing an extension that prevents mining in your web browser; some of them are discussed below.
