Firefox, according to its own Task Manager, shows the browser, not extensions, or particular tabs, using 9GBs of RAM, and 95-120% CPU Usage! This is causing everything to work, as if underwater, typing is slow, hesitates, etc, and opening new tabs sometimes doesn't even happen, and I have to try multiple times, etc. There is no reason Firefox should be using over 100% of my iMac's CPU. Meanwhile, nearly every single open tab is showing less than 1% CPU usage...

I really do want to use this browser, but this kind of memory sucking usage is making really difficult to continue doing.
