When I open my browser, it immediately displays this error message. No matter what web site I navigate to, I get this message. I have no problems with Internet Explorer, so I know this is limited to Firefox. I've been gone for the past 5-6 days and just got home. It worked fine 5-6 days ago. The only change I noticed was that it installed an update to AdBlock Plus. Not sure why that would matter, but I uninstalled AdBlock Plus just to be sure. It didn't help- error is still occurring. I also tried uninstalling and re-installing Firefox, but that didn't help either. Anyone know why this is happening and what I can do to fix it? Thanks!
