Firefox Opens 1,691 Tabs in 15 Seconds

By HTMLGoodies Staff

Mozilla developer Dietrich Ayala recently conducted an unusual test where he timed how long it took various iterations of the Firefox browser to open 1,691 tabs, which Ayala admitted was "ridiculous numbers of tabs." The two most recent versions, Firefox 55 and 56, needed just 15 seconds to complete the task. By comparison, Firefox 51 needed almost 8 minutes to do the same work.

In addition, the latest Firefox builds used dramatically less memory when opening the tabs. Ayala said the improvement was due in part to Mozilla's Quantum Flow project.
