When viewing http://devblogs from Firefox, you are presented with a username/password prompt. This is due to some images that are presented on the main devblog page that are stored in vsweb. Vsweb is running on SharePoint and requires Windows Integrated Authentication. Internet Explorer recognizes that vsweb is on the local internet and automatically sends your credentials, while Firefox needs to prompt. You can easily mimic this behavior in Firefox and avoid the prompt each time you re-visit devblogs by adding vsweb to the list of trusted URIs for ntlm auth. Here’s how to do so:
- In Firefox, type "about:config" the address bar.
- Scroll down to the setting "network.automatic-ntlm-auth.trusted-uris" and add "http://vsweb"to its value.
