Yes have checked that all correct. I previously replied but a page problem came up. I have cleared cache, run anti virus scans, anti malware, ccleaner, rebooted, run updates etc etc lol And now a clean install. Problems have been going on for a while intermittently but more so today for some reason, no updates or downloads that I am aware of.

Are you using any extension that forces a secure https connection?

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
