The Mozilla Foundation, the organization behind the Firefox browser, is working on adding a new feature to its browser that is similar to the Site Isolation feature that Google rolled out to Chrome users this year.....
Mozilla starts Project Fission
But Chrome won't be the only browser with Site Isolation. Work on a similar feature also began at Mozilla headquarters back in April, in a plan dubbed Project Fission.
According to Mozilla sources who spoke with Bleeping Computer, this project is still in its early stages. We were told that implementing a per-domain-process architecture is a relatively simple task, especially after Mozilla has already rolled out Electrolysis, a project that split Firefox from a single-process app to a multi-process architecture.
