Hi, My Linux Mint (a Debian/Ubuntu flavor) when first seen, the Mozilla Firefox 6 Start Page was great. However, when moving away to other sites and then clicking home the response was Alert - "The URL is not valid and cannot be loaded." Having trying everything (apart from using a large club!) I am lost. Any suggestions team? Mark

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

Thanks cor-el, I removed the the default theme, however, it did not alter the problem. But when you said made me think about Firefox and plugins specially designed for Debian/Ubunru/Mint. I found the cause a Ubuntu plugin with two extra connections. Once removed it was fine!! Thanks everyone
