Today we’re proud to announce the initial rollout of multi-process Firefox for Desktop to our general audience. With this, we’re taking a major step forward in improving Firefox for Desktop. Users should experience a Firefox that is less susceptible to freezing and is generally more responsive to input, while retaining the experience and features that users love.

This means when a web page is consuming a large part of your computer’s processing power, your tabs, buttons and menus won’t lock up. Wondering if your Firefox instance has enabled e10s?
