FF10 running well...no crashes...and CPU is at least contained now.
It does spike to 50% sometimes, but only briefly.
However, that's to be expected....I've got 8 windows, and 35 tabs open !
Firefox has always been a resource hog. 10 minute startup time, 8 tabs open - 1.5GB memory usage / 20% constant CPU usage. Dont even know why im still using this piece of crap.
I stayed with it because it has some well thought out features e.g. 'paste and search' saves a few mouse clicks day but i am now at the stage where I feel I have to take the data loss (e.g. history) just to get away from it.
I am also getting constant freezing despite a i7 950 - problem goes away on restart, this suggest to me it is a FF problem.
FF 10.0.1 came out....and cpu seems reasonable.
All of that spiking is caused by staying on pages that have a lot of Javascript. www.cboe.com is notorious for hogging the entire CPU just for quotes.
