The next version of Mozilla’s browser, Firefox 85, will arrive in January with a new feature that will improve users’ privacy by more effectively combating the action of crawls that can be found on the web.

After Safari and more recently Google Chrome, Firefox will incorporate network partitioning. A feature being developed in a group on privacy of the World Wide Web Consortium as a new standard to make it difficult for third party services to track without users being practically aware of it.

The new feature is intended to make it more difficult for third parties to track

Very simply explained, network partitioning consists of distributing the information that a browser stores as it is used to access different websites: image cache, font cache, favicon cache, HTTP cache… If previously this data was saved in a single space and someone accessed it, they could see the rest of the saved data. Now it won’t be exactly like that.

This new feature will create spaces for each of the websites you visit. In this way, a given service hosted on a given website will only be able to see the information enabled for that website, that is, its own information. The tracking, therefore, is difficult.

This partitioning system, although similar to that already present in Apple and Google browsers, is more ambitious. This may mean that some performance is lost, as happened to Chrome with Google fonts, but Mozilla is willing to assume these inconveniences due to the benefits of the feature for users.
