Firefix 23.0.1 is freezing requiring a hard restart to the computer.
I am running an older machine, but with a fresh install of Windows 7. Until the latest update, I had no issues with the versions of Firefox since my last OS install. Now when I am in the latest Firefox 23.0.1, I get occasional freezing that will lock the entire machine and need a hard restart. I am still diagnosing, but to date the only constant I know is Firefox. I have not experienced the same freezes using IE.
Occasionally I will think the freeze is happening when I lose both keyboard and mouse control during a Firefox session, but after 1 to 2 seconds, they both return. Typically though, it just freezes. Most times it occurs while I am away from the keyboard getting coffee or something. It is so transparent, the only thing that tells me the freeze occurred (other than loss of mouse and keyboard) is the system time still being several minutes ago.
I have seen the other forum message regarding Firefox 21 and Firefox 22, but I figured I ask in a new message regarding Firefox 23.
I have done the reset to Firefox as of last night. I reloaded Ghostery as my only Add-On, which was the only Add-On running during earlier versions of Firefox. Already this morning I have had the 1 to 2 second pause, but no freezing yet. (Now Troubleshooter has been added due to this message.)

I've been wrestling with this problem for a couple of weeks (ever since Firefox updated to the latest version, I now realise) but only gradually worked out what was causing the freezes. It took a day of using Chrome (ugh!) to decide to Google "Firefox crashes PC".
Thank you for the solution! If it doesn't work, I'll report back...
