This is driving me mad. Bloody computers. I'm running Firefox 3.6.24 on Vista and am unable to access certain web sites such as Megaupload and Imagebam, I get a "Problem Loading Page" message with the following info;

The connection was reset

The connection to the server was reset while the page was loading.

* The site could be temporarily unavailable or too busy. Try again in a few
moments.

* If you are unable to load any pages, check your computer's network
connection.

* If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.

Does anyone know why this is happening? Help please!
