Firefox 69 blocks 3rd-Party Tracking Cookies and Cryptominers By Default


Mozilla has enabled the “Enhanced Tracking Protection” feature by default in the new version of their web browser, Firefox 69 for Windows, Mac, Linux, and Android.

The company had already enabled the “Enhanced Tracking Protection” setting by default in June this year, but it was available only for new users who downloaded and installed a fresh Firefox. The remaining users had options to either enable the feature manually or wait for the company to activate it for all users.

The Enhanced Tracking Protection will automatically be turned on by default for all users as part of the “Standard” setting in the Firefox browser, blocking known “third-party tracking cookies” and web-based cryptocurrency mining scripts.

Firefox Blocks Third-Party Tracking Cookies

Cookies are usually created by a web browser when a user visits a website. It helps the site to remember information about your visit, that includes your login information, preferred language, items in the shopping cart etc.

While a third-party cookie is set by a website other than the one you are currently on, thereby letting them to offer features like blogs having comment system that works with Facebook account.

The third-party cookies also allow advertisers and websites to track and monitor user’s online behavior and interests, known as ‘tracking cookies’ using which they display relevant advertisements, content, and promotions on the websites a user visit. This has caused serious privacy concerns among Internet users.

In order to find out which third-party cookies are being used for tracking, the Firefox web browser depends on an open-source anti-tracking tool called Disconnect that lists known third-party trackers.

Firefox 69 will now block all known third-party tracking cookies by default that collect and keep data about the users’ activity across multiple sites or applications.

Firefox Blocks Cryptocurrency Miners

Web-based cryptocurrency miners are largely misused by hackers and also by websites and mobile apps by using the CPU power of your PCs to secretly mine cryptocurrencies—often without the user’s knowledge.

Firefox 69 also blocks web-based cryptocurrency miners by default, thereby preventing draining your CPU usage and battery power of your computers.

This feature was already available in previous beta versions of Firefox, but now it has become standard to all.

A type of script which also tracks your activity on the Internet are Fingerprinting scripts. However, in the new standard Mode of Firefox, there is no option to block fingerprinting scripts by default.

But the users can block fingerprinting scripts by enabling the “Strict” Content Blocking mode through Firefox’s Preferences menu, under “Privacy & Security.”

Disabled Adobe Flash by Default

Firefox 69 also disabled the Adobe Flash Player by default and will now it will ask for the user’s permission before turning on Flash on websites.

Mozilla has removed the “Always Activate” option for Adobe Flash plugin content from its browser, which suggests there is no longer a need to identify users on 32-bit Firefox version on 64-bit operating system version, reducing user agent fingerprinting and providing a greater level of privacy.

The users can also block auto-play videos that automatically start playing without sound, numerous performance and UI improvements on Windows 10, and better battery life and download UI on macOS.

Those users who haven not downloaded Firefox 69 for your desktop can do so now from the official website. All existing Firefox users gets upgraded to the new version automatically.
