Is Firefox the fastest browser?

Browse faster

Every computer program you run takes up some memory. If your computer is low on memory, this can cause… a…… significant………… slow down. Firefox aims for a balance – using enough memory to let you browse smoothly and leaving plenty of memory to keep your computer responsive.

Multi-tasking with multiple tabs

Firefox is a multi-process browser, which means that your tabs stay fresh and won’t take forever to reload. With 86% less lag time, you can switch quickly between tabs even when your little inner voice says you have waaay too many tabs open.

Faster gaming

We led the tech to run 3D games at near-native speeds, and now Firefox is bringing even better performance to online gaming. Our powerful browser reduces lags, speeds up ping times and optimises overall gameplay through faster, leaner browsing.
