Mozilla Corporation has developed a built-in script blocker for mining cryptocurrency in Firefox. New development will protect users from cryptojacking.
We’re working on blocking cryptominers! Cool, but wtf even are cryptominers?
Through browsers, they can use your computer's power to make $ (cryptocurrency, specifically). That'll slow you down, drain your battery AND could rack up your electric bill. https://t.co/VqbfJT0EZK

The option of automatic script blocking for hidden virtual currencies mining was added in test browsers of Mozilla Firefox – Nightly and Beta. If the tool is tested successfully, it will be integrated into all versions of the Firefox browser.
In addition to the cryptominers blocker, the last update of Firefox has the anti-fingerprinting feature: Mozilla developers added a tool to block scripts that collect hardware configuration information and use it to identify Internet users.
The new Firefox system blocks 20 different crypto-mining scripts, including those best known as CoinHive, JSE and MineXMR, which are used to mine the anonymous virtual currency Monero (XMR). Mozilla employees are calling on all users to turn on the cryptojacking protection after the update is released on the standard version of Firefox. This can be done in the browser settings:
- go to the Firefox main menu;
- select the option “Settings”;
- go to the tab “Privacy and Protection”;
- in the “Content Lock” menu, check the box next to “Cryptominers” and “Fingerprinters”.
After protection is enabled, the browser will automatically block scripts that are in the Disconnect site list. Mozilla Corporation warns that reliable Internet portals could be blacklisted, in which case you should send a bug report.
In the Opera browser, the cryptojacking protection feature has been running since 2018. However, unlike Firefox, Opera uses the NoCoin blocker, which prevents the launch of scripts to extract digital assets.
