Mozilla is currently testing a major new security feature for its Firefox browser which will separate every website into its own process.
Site Isolation is designed to prevent Spectre-like side-channel attacks in the popular open source browser.
In a blog post, Anny Gakhokidze, a Senior Platform Engineer at Mozilla working on Site Isolation, explains that it builds upon a new security architecture that extends current protection mechanisms of the browser by making it load each site in its own operating system process.
