Firefox is catching up on Chrome. The Mozilla Foundation has just announced that the security feature Isolation site is now being tested on Firefox, and can be activated in the Nightly version reserved for testers.
This function allows you to isolate the pages and iFrame websites. Thus, a malicious site cannot attempt to steal or modify the data of another site. Google has taken a lead in this area since the Site Isolation function is present in Chrome since version 67.
The arrival of the function in Firefox required two years of code rewriting, as part of a project called Fission. It represents an asset for the safety of the users but risks increasing the memory consumption of the browser. The stable version should be available in the first half of next year.
