For the past two years, Mozilla has strengthened Firefox protections against tracking Y "Enhance Tracking Protection »is in charge of it in Firefox and automatically protects user privacy while browsing the Internet.
Block many trackers that follow the user everywhere online to collect information about their browsing habits and interests. TIt also includes protections against malicious scripts, such as those that drain your battery or use system resources for cryptocurrency mining.
Firefox uses a list of known trackers provided by Disconnect. By default, Firefox blocks the following types of trackers and scripts:
- social media trackers
- cross-site tracking cookies
- fingerprint detectors
- cryptocurrency miners
These trackers are hidden in ads, videos, and other content on the page. Blocking them can cause some websites to malfunction.
This type of work by Firefox is not new, Ya que in version 63 (which was released in 2018) came with improved tracking protection, blocking cookies and access to storage from third-party trackers.
Later in Firefox 65 (released in January 2019) Added content blocking controls with three options for the blocking feature:
- Standard - The default, where Firefox blocks known trackers and third-party tracking cookies in general.
- Strict - For people who want a little more protection and don't mind that some sites don't work.
- Custom - for those who want full control over which trackers and cookies they want to block.
For version 69 that arrived in September, many aspects have been improved with tracking protection enabled by default and cryptocurrency mining blocked by default.
After all this journey, the new Enhance Tracking Protection 2.0 that Mozilla has started in Firefox will introduce several improvements.
Last year Mozilla enabled ETP by default in Firefox, because the publisher felt that you don't need to understand the complexities and sophistication of the ad tracking industry to be safe online.
ETP 1.0 was your first big step in making this commitment a reality. with users. According to the publisher, since it enabled ETP by default, Firefox has blocked 3,4 trillion tracking cookies. With ETP 2.0, Firefox brings an additional level of privacy protection to the browser.
Since the introduction of ETP, the technology of the advertising industry has found other ways to track users: creating solutions and new ways to collect your data to identify you while browsing the web.
Redirect tracking bypasses Firefox's built-in third-party cookie blocking policy by taking you through the crawler site before entering the website of your choice. This allows you to see where you are coming from and where you are going.
Here's how Mozilla explains it:
Let's say you're browsing a product review website and clicking a link to buy a pair of shoes from an online retailer. A few seconds later, Firefox goes to the retailer's website and the product page loads. Nothing seems out of place, but behind the scenes they kept using redirect tracking »
Enhanced Tracking Protection 2.0 tries to solve this problem checking if cookies and site data from these trackers should be removed.
The feature prevents known trackers from accessing information by deleting cookies and site data every 24 hours. Since you look like a new user the next time you visit the tracker (after 24 hours), you cannot create a long-term profile of their activity.
“With ETP 2.0, Firefox users will now be protected against these methods as it checks to see if cookies and site data from these trackers need to be removed every day. ETP 2.0 prevents known trackers from accessing your information, even those that you have inadvertently visited. ETP 2.0 clears cookies and site data from tracking sites every 24 hours.
Ultimately, Firefox tries not to delete the cookies of the services with which it interacts, like search engines, social networks and email account.
The browser does not touch the sites that have been interacted with in the last 45 days, even if they are trackers so that you do not disconnect from the sites you visit, so that you are not crawled indefinitely based on the sites you visited only once.
