I installed Saucy a couple of days before release and have been experiencing this more and more frequently. To the point that I have now ditched Firefox and am using Chromium instead. Version 26 update didn't help, nor did putting cache into RAMfs. Possibly loading multiple flash players triggers the hard freeze (only way out is to kill the application) but I have not been able to properly report a bug with apport.
