This has been going on for around 5 days: most times when I start up the computer, pages refuse to load and I receive message 'Firefox is configured to proxy server that is refusing connections.' It's not only Firefox, though, because Chrome and IE don't load either. Occasionally, the connection 'quits' and I get that message when I'm working online. The only way I've been able to temporarily fix the problem is by doing SystemRestore when this occurs- but it gets awfully time-consuming and inconvenient. The internet company said to contact Microsoft, but Microsoft's advice was similar to a family member's: change proxy settings. That didn't work either. Anybody have knowledge/advice about this?
