Edge and Chrome have a automatic sleeping tab feature where after a certain amount of time of you not using a tab, the tab goes to sleep to help preserve memory, and when you click back on the tab it wakes up. Firefox needs a feature like that. Chrome and edge have it that the tabs go to sleep after a certain amount of time (1-2 hrs). While Firefox relies on addons for that kind of stuff which i find is annoying. it should be also default. It would be really nice is Firefox would add this feature because i want to be a forever Firefox user, and this would really benefit not just mine, but Everyone's Firefox experience! Thanks for considering my idea!
