Mozilla has released a new version of Firefox, claiming it's faster than ever thanks to a strategy called "voluntary procrastination." Unlike human procrastination (moving activity like washing dishes instead of completing a tax return), the Mozilla system involves creating a task list and performing Tasks at the optimal time. Features that are rarely used have been prioritized, which means that the page can be rendered faster. For example, the browser won't look for alternate style sheets before the page loads, and it won't load its autofill module until there's a form on the screen. who will use it If your system runs out of memory (less than 400 MB), Firefox now suspends all tabs you haven't used for a while. All hanging tabs will be reloaded when clicked. Mozilla also states that the browser will "skip a bunch of useless work" on startup if you are using a custom theme or ad blocker. You didn't explain exactly what this implies, but it probably means that it doesn't load elements that will be replaced by browser extensions.
