Firefox starts and runs, then multiple sites claim "no connection" while other browsers work.

I am using Firefox and browsing, when it seems that Firefox loses the connection: sites won't load or refresh; Yahoo mail says "no internet connection." However, Internet Explorer still works during these times, and the Wi-Fi modem is active. I've tried resetting the modem, and re-starting the computer.

Running Windows 8.1.

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
