The Mozilla Foundation plans to add a new anti-tracking feature called Network Partitioning within version 85 of the Firefox web browser, which is due to arrive in January 2021.
The feature is based on client-side storage partitioning, a new standard currently being developed by the World Wide Web Consortium’s Privacy Community Group.
Privacy researcher Zach Edwards said: The Network Partitioning feature is very technical, and can be somewhat simplified by saying: Your browser has many ways in which it can save data from websites, not just files. Link definition.
He added: These other storage mechanisms include HTTP cache, image cache, favorite icon cache, font cache along with a variety of caches and other storage mechanisms that can be used to track people across websites.
All of these data storage systems are shared between websites, Edwards says, and the difference is that the Network Partitioning feature allows Firefox to save resources, such as: cache, favorite tools, CSS files, images and more, on a basis of every website in the same group, not together. .
This makes it difficult for websites and third parties, such as advertising companies and web analytics, to track users, given that they cannot verify the presence of data from other sites in this common pool.
According to Mozilla, the Network Partitioning feature is coming to Firefox under version 85, but it will not be the first browser maker to use it.
The first browser maker to do this was Apple in 2013, when it started splitting the HTTP cache cache, Edwards said, and Apple continued this approach by splitting more user data storage systems years later, as part of the blocking feature. Traceability.
Last month, Google split the HTTP cache with Chrome 86.
Mozilla’s team expects some performance issues for the sites loaded in Firefox, but is prepared to take it up in order to improve the privacy of its users.
Most digital policymakers and strategists focus on the end of the external cookie, but there are a variety of other technologies and user tracking strategies that browsers should eliminate.
Mozilla said: Adding the Network Partitioning feature within the 85th version of Firefox allows it to better block super cookies, which are cookies that misuse various shared storage media in order to allow advertisers to track a user’s movements across the web.
