FSF Announces 'JShelter' Browser Privacy Extension to Block Fingerprinting, Tracking, and Malware

Sunday October 3, 2021. 01:34 PM , from Slashdot
This week the Free Software Foundation (FSF) announced JShelter, 'an anti-malware Web browser extension to mitigate potential threats from JavaScript, including fingerprinting, tracking, and data collection.'
The browser add-on — supported by NLnet Foundation's Next Generation Internet (NGI) Zero Privacy & Trust Enhancing Technologies fund — is currently 'in development and the first release is available.'

This browser add-on will limit the potential for JavaScript programs to do harmful actions by restricting default behavior and adding a layer of control... Accessing cookies, performing fingerprinting to track users across multiple sites, revealing the local network address, or capturing the user's input before they submit a form are some examples of JavaScript's capabilities that can be used in harmful ways. JShelter adds a safety layer that allows the user to choose if a certain action should be forbidden on a site, or if it should be allowed with restrictions, such as reducing the accuracy of geolocation to the city area. This layer can also aid as a countermeasure against attacks targeting the browser, operating system, or hardware levels... [The extension] will ask — globally or per site — if specific native functions provided by the JavaScript engine and the Document Object Model (DOM) are allowed by the user. It will also link to an explanatory page for each function, to raise awareness of related threats. Depending on the function being addressed, the user will have the option to allow it, block it, or have it return a custom value...

'Our browsers have become perhaps the most critical of tools we depend on, and yet the browser environment is far from healthy,' says Michiel Leenaars, director of strategy at NLnet Foundation and coordinator of NGI Zero. 'Dominant corporate behavior from a small amount of actors has been aggressively reshaping the evolution of the Web, and that is starting to wreak havoc. Despite an enormous systemic dependency, we as users have very little control over what browsers allow and share — leading to significant risk as the most powerful tools in the shed are essentially left unprotected for every casual Web site to abuse. JShelter is a great initiative to help empower us all, to help us gain better understanding and to better safeguard ourselves from obvious and otherwise unavoidable harm.'

The effort is part of a larger, multi-year campaign from FSF on JavaScript on the Web started in 2013, which among others includes the development of GNU LibreJS and outreach to users and developers about nonfree software inside the browser. The GNU LibreJS extension detects JavaScript web labels and assists users with running only JavaScript distributed under a free software license, according to their ethical convictions and individual preferences.

'JShelter will help protect users from critical threats now, and contribute significantly to progress on the necessary longer-term cultural shift of moving away from nonfree JavaScript,' said Ruben Rodriguez, former FSF chief technology officer.

'This is a project I've been looking forward to for years, tired of dealing with all kinds of potential antifeatures in the browsers I use and distribute, and having to figure out some countermeasure for them with configuration changes, patches or extensions. Being able to wrap the JavaScript engine in a layer of protection is a game changer.'
