There are a number of things people don’t need to have happened, while they are browsing the internet. They supposedly don’t need a sketchy website to identify and track them. People obviously don’t need a webpage to use their computer’s hardware and electricity to mine crypto-currency that they don’t get any cutoff. Mozilla is now tackling these issues with a new security tool within the Firefox browser.
New security tools aren’t here for the wide-release version of Firefox yet. Mozilla already launched on both Firefox Nightly 68 and Firefox Beta 67. They aren’t enabled by default, but Mozilla has planned to eventually have them turned on automatically in all versions of Firefox. Scripts can identify the hardware in your computer and device configuration information in the case of fingerprinting to create an identifier for you that is independent of cookies.
So, clearing the cookies from your browsers won’t trick the sites, since they’d be able to check your computer’s details again using the scripts and recognize it from the previous visit. Crypto-jacking scripts, meanwhile, can be detrimental to your online experience, as they’ll use your computer’s processing power and your battery or electricity to mine crypto-currency. It can be harmful to your computer while also slowing down the performance of other tasks.
The new security tool of Firefox works by blocking these scripts. Mozilla has worked together with Disconnect to identify domains that serve these fingerprinting and crypto-jacking scripts. If they are detected, Firefox’s Content Blocking protections will stop them from running. Firefox users can enable these security tools in Firefox Nightly 68 and Beta 67 within the Firefox main menu > Preferences > Privacy and Security. Select Custom under Content Blocking, and checking Crypto-miners and Fingerprinters.
