You put windows nt, but your build id says windows 7. What are you using?
I dodn't put NT anyhere knowingly, the build ID is correct. It's Windows 7 64-bit. I'm using the normal 32-bit version of Firefox though.
ok, changing platform to x64. There is only one version of ff for both x32 and x63.
I am not seeing any cpu spike on this page. Either scrolling or not. CPU usage stay normal. Is it still happening with 3.5.6 or later in a new profile?
Can't reproduce with current FF version.
