As I said, no other pages will load, and i get this same error message every time. I tried uninstalling and redownloading firefox with the same result, which makes no sense to me. Any help greatly appreciated.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
