I have recently been suffering from some lockups and crashes. The need for a task manager was incredible and I lamented the lack of one.
How wrong I was. The hot key is Esc+Shift. Well. I feel stupid.
What I discovered using the task manager was that Adblock Plus was eating my RAM. Google Drive Sync, the ability to use and edit drive documents offline is also chewing on my memory.
As valuable as I find Adblock, I decided it to turn it off.
We shall see what happens.
