Lazy Pins от ubunatic

Lazy Pins is a Firefox extension that prevents pinned tabs 📌 from auto-loading on browser startup. They will only load, when clicked. This allows you to keep important tabs pinned without the overhead of loading them immediately.

• Saves memory 🌱 and improves startup performance 🐎 for new windows.
• You 🫵 decide when tabs are loaded lazily by clicking 🖱 on them.
• You can also unload tabs on-demand to free system memory when needed.
