I guess I enjoy being in the tech minority: a Linux user in a Mac/Windows world, a Firefox user in a Chrome/Edge world. Detractors often cite Firefox as being a memory hog. Nice to see Mozilla taking that seriously although projects like Electrolysis and Servo which aim to thoroughly modernize the aging browser will do far more to address that complaint in the long run. In the short term being able to tweak the browser in this way isn’t a bad stepping stone.
Mozilla engineers are working on a new section in the browser’s preferences that will let users control the browser’s performance.
