Recently there have been pornographic pop-ups on my computer. They have all been on Mozilla Firefox. Normally I ignore these and exit out of them. But the last one was so horrifying that I need to write to you. Something needs to be done. This pop-up was not only porn, but the women seemed to be held down, without a choice. Whether or not this is real, I am still sick just thinking about it. If there are any sites to block pop-ups, please let me know, or I am switching my browser. Thank you.
