What is multi-process tabs architecture in Firefox? In simple word, Firefox will open each tab in a new process, which makes the browser more stable and less resource hungry. Similar feature is already available in the latest version of Google Chrome and Internet Explorer. The multi-process tabs architecture is currently available in Nightly builds of Firefox. It is not fully implemented in the release version of Firefox. If you want to try it, download the nightly build and enable it from Firefox’s about:config page. Follow the instruction given below. Open Firefox browser, type about:config in the address bar and hit enter.In the search field, type browser.tabs.remote. Double-click on the browser.tabs.remote to toggle its value to true. Then restart your browser.
Warning: Do not try this in release version of Firefox. Your browser will crash! Now, each tab in Firefox will open in a new process. The webpage titles are shown underlined in different tabs, which mean the tabs are running in multiple processes.
