This problem happens when I switch networks. I sometimes need to hop on my phone's hotspot to open a program, after which I switch back to my Verizon hotspot. When I switch from my phone hotspot back to the Jetpack hotspot, sometimes nothing happens, but other times, Firefox opens automatically without me clicking the icon, and it opens to MSN.com--even though I have never been to MSN.com and do not have it set as my homepage. So far, I have tried making my homepage a blank page in Options. When I open Firefox myself, I now have a blank page instead of the homepage, so I know it worked. I disabled the plugin from Cisco and that seemed to work for a while. Now it has started happening again; I do not understand why, and I do not want MSN as my homepage. I also do not want Firefox to open automatically without me doing anything. That's really creepy.
