Over the last few months, the developers of Firefox have been slowly rolling out technology that will bring the browser up to par with competitors when it comes to speed, security and reliability. Others like Chrome, Safari and Edge are already designed using multi-process, to separate tabs, add-ons and even rendering from the main browser. As it stands, Firefox 50 users with extensions approved for multi-process are already using the technology, which the team says has increased responsiveness by 400 percent, and 700 percent while pages are loading.
