Fission is Mozilla's project to implement Firefox site isolation: . This introduces a major architecture change in Firefox such that a unique process is allocated for the main web page and for each unique third-party iframes will be loaded iframe embedded in separate processesit, thereby safely sandboxed from the web page's content processsandboxing them and further strengthening Firefox security.
