Note: Assumes internal SharePoint deployment using NTLM authentication where client machine is a member of the same domain where SharePoint is deployed
I discovered this browser workaround several years back and thought I’d post here for reference. Here is the original source:- http://www.cauldwell.net/patrick/blog/PermaLink,guid,c7f1e799-c4ae-4758-9de7-5c3e7a16f3da.aspx.
When using Firefox, avoid being prompted for logon when browsing to SharePoint sites by making the following configuration changes to your Firefox browser:
- In the Firefox address bar, type about:config then press <return>
- On the subsequent about:config page, scroll down until you locate the key named network.automatic-ntlm-auth.trusted-uris.
- Right-click the network.automatic-ntlm-auth.trusted-uris key and click Modify. Enter the name of the SharePoint site (see below) and then click OK. For multiple sites, separate each name by a comma.
