Mozilla is implementing a new feature in Firefox that will protect users from attacks launched via malicious websites.
This new security mechanism can offer extra security to users in their web browsing thanks to the dynamics it implements with each website.
Mozilla is implementing the Site Isolation feature that can protect users from attacks such as Meltdown and Spectre, thanks to its security mechanism:
Site Isolation is based on a new security architecture that extends current protection mechanisms by separating (web) content and loading each site in its operating system process. With the Site Isolation architecture in place, we can provide an additional security boost to Firefox to keep you and your data secure.
That is, when it detects that the websites opened in the browser are different, a kind of bubble will be created to isolate the content of each of them in separate processes. That way, if the user encounters a malicious site, it will not be able to access content outside its “bubble” and steal user data corresponding to processes on other websites.
An extra security measure that ensures that sensitive user data, shared only on certain websites, will be kept safe during web browsing. And of course, it will also contribute to browser performance and user experience, as websites will load faster thanks to this mechanism.
This feature has been in testing for months, but now Mozilla is extending it to some of the browser versions. It is not enabled by default, so users will have to follow the steps detailed by Mozilla at this link.
