Lately I am noticing when I first startup Firefox, while it's loading my homepage which happens to be cnn.com, the page comes up nice. While it appears to be completely loaded there is more activity going on. So much so, that I can't click onto anything for like 15 extra seconds.
I pulled up Task Manager and don't see anything out of the ordinary running. Does anyone know what is happening? Is this normal? Do you experience the same thing? I have AdBlock Plus loaded and updated with tons of filters and I just cleaned up my system by running Malwarebytes and SuperAntiSpyware. Any ideas?
