When I logged into my main Verizon page, I got this message:
You are using an outdated browser that verizon.com does not support. For a better experience, please use a supported browser.
It is at the top of my screen right now. But when I look at the supported-browser link, it says Firefoc 3.x is supported and I am running Firefox 3.6.11 that is a supported browser. So something is wrong with your system that mis-identifies my browser.
verizon.com supports Microsoft® Internet Explorer 7.x and 8.x, as well as Mozilla Firefox™ 3.x on the PC.
