Mozilla Firefox is one of the oldest browsers on the internet. The non-profit foundation, Mozilla, is known to release new versions of Firefox every once in a while. It is famous for its user extensions, which rival the likes of Google Chrome in terms of quality as well as quantity.
Once considered as a memory hog, Mozilla has steadily changed Firefox’s image and memory consumption and now it is one of the most optimized browsers on the internet.
Recently, the company launched Firefox 88, improving things on many fronts and introducing numerous new features. The most notable feature is the addition of PDF forms, which now supports JavaScript and even allows it to embed in PDF documents.
Even Linux users have a reason to rejoice. In case you are using a Linux based distribution on a laptop or a device with a touchpad, you can smoothly use the pinch to zoom gesture. Another handy feature is the ability to localize margin units when front printing.
Mozilla Firefox has also taken user privacy to the next level, with users now protected against cross-site privacy leaks. The browser is now able to isolate the window name and the date, preventing other tabs from eavesdropping.
According to Mozilla,
The window.name property of a window allows it to be able to be targeted by hyperlinks or forms to navigate the target window. The window.name property, available to any website you visit, is a “bucket” for storing any data the website may choose to place there. Historically, the data stored in window.name has been exempt from the same-origin policy enforced by browsers that prohibited some forms of data sharing between websites. Unfortunately, this meant that data stored in the window.name property was allowed by all major browsers to persist across page visits in the same tab, allowing different websites you visit to share data about you.
Privacy Protection enabled by default in Mozilla Firefox 88
In case you are wondering how to enable the new feature, Mozilla states that starting with Firefox 88, it will be enabled by default.
To avoid unnecessary breakage, if a user navigates back to a previous website, Firefox now restores the window.name property to its previous value for that website. Together, these dual rules for clearing and restoring window.name data effectively confine that data to the website where it was originally created, similar to how Firefox’s Total Cookie Protection confines cookies to the website where they were created. This confinement is essential for preventing malicious sites from abusing window.name to gather users’ personal data.
