By using JavaScript, you can implement moving content and various convenient functions on the website in cooperation with the functions of the browser by a program that is automatically executed when the browser loads the website. However, due to the large number of functions, there are also many vulnerabilities, and privacy and security issues have also been pointed out.
Therefore, the Free Software Foundation announced `` JShelter '', a browser extension that controls browser functions to prevent harmful JavaScript behavior. 'JShelter not only provides users with the protection they need, but also supports the Free Software Foundation's philosophy of the power and usefulness of free software,' said Greg Farrow, campaign manager at the Free Software Foundation, in a statement. It will prove the validity of this and will also spark a discussion about the dangers of 'non-free' software on the web.'
According to the Free Software Foundation, misuse of JavaScript can lead to various threats to user security and privacy, such as creating
To prevent such risks, JShelter checks for each site whether the browser functions provided by the JavaScript engine and Document Object Model are permitted by the user, and provides an explanation of such functions to the user. Users can use JShelter to block unwanted privacy features, issue limited permissions like 'Reduce GPS Accuracy', or set it to return any custom value.
Michelle Lehners of the NLnet Foundation , which backs JShelter, said of JShelter, 'Browsers are probably the most important tool we rely on. But we, as users, have little control over what browsers allow and what information we share. It's an out-of-control and unhealthy internet environment for browsers, and JShelter is a great initiative to help us better understand and protect ourselves from these risks. '' he said.
In addition to the ongoing development project of JShelter, the initial release has already been released under the name `` JavaScript Restrictor '', and it can be installed for free on Google Chrome, Mozilla Firefox, and Opera.
