Tab Memory Monitor od R0xuwan

Tab Memory Monitor helps you keep Firefox running fast by
showing real-time memory usage and letting you sleep unused tabs.

Features:
- Live graph showing JS heap memory over the last 60 seconds
- Memory cards showing current usage, peak usage, and open tab count
- See which tabs are active and which are sleeping
- "Sleep inactive tabs" button to instantly free memory
- Auto-sleep toggle that automatically suspends tabs inactive
for X minutes
- Adjustable timer slider from 5 to 60 minutes
- All settings saved automatically

Why use it?
Too many open tabs slow Firefox down. Tab Memory Monitor gives
you a live view of memory consumption and lets you reclaim it
instantly — without closing tabs you still need.
