Since Monday I have been unable to load up any secure site (e.g. that starts with "https://....") in Firefox. It says it's loading, but sits there for a few seconds and then comes up with a "Problem loading page" screen. The same sites open fine in IE. These sites worked fine in FF until this week. I haven't changed any FF settings, I have cleared all cache, done a complete reinstall of FF - all to no avail. I have no addons, and all plugins are disabled. I am running Windows 7 Professional. Help! == Operating system == Windows 7 Professional
