An anonymous reader quotes a report from BleepingComputer: Mozilla engineers are working on a new section in the browser's preferences that will let users control the browser's performance. Work on this new section started last Friday when an issue was opened in the Firefox bug tracker. Right now, the Firefox UI team has proposed a basic sketch of the settings section and its controls. Firefox developers are now working to isolate or implement the code needed to control those settings [1, 2, 3]. According to the current version of the planned Performance settings section UI, users will be able to control if they use UI animations (to be added in a future Firefox version), if they use page prefetching (feature to preload links listed on a page), and how many "content" processes Firefox uses (Firefox currently supports two processes [one for the Firefox core and one for content], but this will expand to more starting v54).
