Firefox stops responding after using it for about two days. Everything works fine for about 2 days of use, then pictures / flash stops loading, then it stops responding to clicks, and finally it gets totally unresponsive. Moreover, I can't even quit firefox then. I will have to force-quit. Has anyone observed this? This was not happening when I was on firefox 2. Now it happens now almost every two days, and gets to my nerves. Is it just happening on my system or have you seen this too?
