While using the browser, an alert came up for a security update. I did it and it closed/reopened the browser and while reloading all the tabs I had open, none of them were able to connect and kept coming up with a warning that it wasn't fully complete or something.. so I closed it and opened a new browser and it wouldn't load (firefox would open, but "problem loading page" happened.) I rebooted and still the same, mind you AIM and Internet Explorer still worked, so it wasn't/isn't the internet. I uninstalled and reinstalled, rebooting after both, and still nothing's working.
In the settings, it says the newest update was today and it was done successfully. When I go into "help" and check for updates, it comes up with "there were problems checking for, downloading or installing this update. Firefox could not be updated because: AUS: Update XML File Malformed (200) You can update Firefox manually bu visiting this link and downloading the latest version: (link to mozilla)"
Since I've already reinstalled the newest version, I don't know what the problem is, anyone?
