Every morning when I get to my PC, FF is slow to wake up and is using 50% of the CPU cycles
I leave my PC on overnight. When I get to it in the morning, move the mouse to wake it up, FF is black and slow to wake up. There are 4 tabs open. It seems to stay this way until I shut it down and restart and then it's fine all day. What is it doing upon wake up that causes this?

I remember reading some where that if you leave Firefox open for more than an hour it can use a lot of memory. Here's some troubleshooting steps to reduce memory usage on Firefox: http://mzl.la/17zWHQ2 http://mzl.la/17zWHQ2 I'd recommend closing Firefox overnight and using the restore previous session option: http://mzl.la/1dUS10H http://mzl.la/1dUS10H
B-Dubs,
I'll try that and see what happens. But the funny thing is that this just started recently and I really haven't done anything to the PC other than a few Windows XP updates.
Thanks.
B-Dubs,
Did as you suggested and sure enough, no problem this AM when I started FF. What would have caused the program to start grabbing CPU resources while sitting idle for 12 hours? Is this something that should be reported as a bug? I'm on 23.0.1.

Honestly I'm not sure what would've made it suck CPU.
There's this help article on reducing CPU usage: https://support.mozilla.org/en-US/kb/firefox-uses-too-many-cpu-resources-...

Thanks for trying B-Dubs. I've contacted a moderator.
You're welcome and I hope you find an answer to your question.
B-Dubs,
It appears that by leaving a Tab open overnight with the Wall Street Journal Market Data is causing the problem. When I close that Tab and come back to my PC next morning, all is fine. That particular page updates automatically with market data about every 10 minutes. What would cause it do do what it does to me?
Hi jbacinti, Firefox 21-22 had a problem waking from sleep on Windows 7: Firefox tabs were blank and took forever to redraw, even though you could switch tabs and open news ones immediately. Killing Firefox (e.g., using the Task Manager) and restarting it was the only quick workaround. That bug was fixed in Firefox 23 -- or thought to be fixed. (Example: FF 21.0 Unresponsive after Sleep - Windows 7.0)
One hypothesis for why Firefox was sluggish waking from sleep was queued script operations. I don't know whether that was proven, but reloading the page would re-run the scripts in the page.
In your scenario, did Windows go to sleep or just save battery by turning off the screen and perhaps spinning down the hard drive? This might create the conditions for a different or related bug.
Windows did not go to sleep and my PC is a desktop with power saving turned off. When I move the mouse to turn off the Screen Saver, both open programs, FF and T-bird, have an all black screen within their respective borders. Then slowly the windows are painted as they should look. Hope this helps. I am running 23.0.1.
