Mozilla has announced a new version of Firefox. The company claims it faster than ever due to a strategy called Procrastinate on Purpose. Mozilla’s system involves creating a ‘to-do’ list and performing tasks at the optimal time, unlike human procrastination or displacement activity such as washing the dishes rather than completing a tax return. Some rarely used features are de-prioritized and the page can be rendered more rapidly. The browser won’t search for alternative style sheets until after the page has loaded. It will not load its auto-fill module until there’s actually a form on the screen to use it.
Firefox will now suspend any tabs that you haven’t used for a while if your system is running low on memory approximately below 400MB. Any suspended tabs will reload when clicked. Mozilla has also indicated that the browser will skip a bunch of unnecessary work at launch if you’re using a custom theme or ad-blocker. The company hasn’t explained exactly what this involves, but presumably it means not loading elements that will be overridden by browser extensions.
The company promised earlier this year that Mozilla has added 2 major new security features to Firefox 67. The first one is to protect against fingerprinting. It is a technique for identifying specific computers using their unique combination of hardware settings. Once your device has been identified, unscrupulous advertisers can follow you around the web, without tracking cookies. The 2nd security addition gives protection from cryptocurrency miners, which usurp your machine’s resources without permission when you visit an infected website. Both features were first appeared in beta versions of Firefox in April. Now they are ready for general release.
