Firefox 69 blocks third-party tracking cookies, cryptomining by default for everyone

Mozilla has announced that from today its Firefox web browser will by default block third party cookies on Android and desktop. Now, the wait is over.

At present, Mozilla said over 20 percent of Firefox users have the feature enabled but that figure should climb sharply with Firefox 69.

A third-party cookie is set by a website other than the one you're now on, allowing them to offer features like blogs having comment system that works with Facebook account.

Besides this, third-party cookies also allow advertisers and websites to track and monitor users online behavior and interests, commonly known as "tracking cookies" using which they display relevant advertisements, content, and promotions on the websites a user visits.

While most internet users are at least familiar with cookies, crypto-miners are a more recent scourge. This profile is used to track that device across the web.

The latest version of Mozilla's Firefox browser, out now for Windows, macOS, Linux and Android, now blocks third-party tracking cookies and cryptominers by default. This is a sort of attack where crytocurrency miners use your CPU to generate cryptocurrency.

Starting with Firefox version 69.0, ETP will be turned on by default for all users worldwide as part of the "Standard" Content Blocking setting in the Firefox browser.

From now on, the "Standard" mode will also block web-based cryptominers, but the option to block domains that host scripts harvesting a snapshot of users' computer's configuration (aka "fingerprinting" scripts) will be given only to those that opt for the "Strict" Content Blocking mode.

Forward-looking: Mozilla is also working to enable fingerprinting protections by default in a future release.

The Block Autoplay feature is enhanced to give users the option to block any video that automatically starts playing, not just those that automatically play with sound.

The primary beneficiaries of this upcoming update are Macbook users, who can now expect longer battery lives while using Firefox.

With this release, Firefox will disable Flash by default in the browser and will always ask for permission before activating Flash on a web site.

Users can choose the different Content Blocking modes through Firefox's Preferences menu, under "Privacy & Security". This view also allows users to unblock trackers for specific sites.

How can I download Firefox 69?

All existing Firefox users should be able to upgrade to the new version automatically.
