Hi how do I i prevent Firefox from going into efficiency mode. When Firefox goes into efficiency mode it be comes slow and unresponsive. if I manually uncheck efficiency mode in task manager Firefox becomes quicker and less laggy until a few seconds to minutes later it goes back into it. The performance of Firefox in efficiency mode makes it almost unusable and can take up to a minute for it to start working again.

Try to enter about:config in the address bar and set dom.ipc.processPriorityManager.backgroundUsesEcoQoS = false, then restart.
