Tabs Consuming Too Much RAM After Long Browsing Sessions (Memory Auto-Recovery Suggestion)

[mfaq12345]

Many users struggle with Firefox gradually consuming a lot of RAM after keeping multiple tabs open for long browsing sessions, especially on mid-range laptops and low-memory devices. Over time, inactive tabs continue holding memory even when they’re not being used, which slows down the browser and sometimes causes system lag. A helpful improvement would be an automatic memory recovery feature that temporarily unloads long-idle tabs while keeping their session state intact, similar to tab hibernation. This would improve performance, reduce crashes on low-RAM systems, and create a smoother experience for users who multitask with many tabs.

I really agree with this suggestion. The memory buildup from long browsing sessions is something I’ve noticed too, especially when I keep 20–30 tabs open for work. Even when I’m not actively using most of them, Firefox still feels slower over time and sometimes my laptop fan ramps up because of high RAM usage. A smart tab hibernation or memory-reclaim feature would definitely help, as long as it restores the tab instantly when clicked so the workflow isn’t interrupted. This could be a great balance between performance and multitasking, especially for users on lower-spec systems.
