While Firefox continues its research to fork each process as a separate tab, a new extension named Priv8 adds the support for running sandboxed tabs in the popular browser. In one of our earlier articles we explored Firejail which runs Firefox in a sandboxed environment. Priv8 takes it to the next level.
A sandbox tab is unrelated to any other tab and you can open multiple accounts of the same service using it. A sandbox is created by adding a domain to it. The procedure is similar to adding a new site to speed dial. The user can select a distinct colour for the sandbox URL on the tab. A sandboxed tab data is persistent across browser sessions.
