I use windows 8. as I use firefox through the day, it's memory usage keeps climbing. After 1-2 days it goes to 1-2 GB and starts not responding. I usually have 8-10 tabs open. I have the latest version. If I watch the task manage, the memory usage climbs while I watch it.

Maybe consider updating to Windows 10? It has better memory management.
