In a previous post I created a tutorial for how to stop SharePoint from prompting for credentials in Internet Explorer, but what if FireFox is your default browser?
Unfortunately, it is not as easy to add a trusted intranet site in FireFox, because the option doesn’t appear in the Setting menu. Additionally, FireFox uses a prefs.js file to store user preferences, and this file should not be edited. You can, however, overwrite these preferences with a user.js file.
Here are the steps you should follow to add a trusted intranet site in FireFox:
- Click on your windows Start button.
- On the Start screen select the Search icon.
- Paste the following in the searchbox: %APPDATA%\Mozilla\Firefox\Profiles\ and push the enter key.
- Your FireFox Profile folder should display. Open the folder.
- You should see a file called prefs.js. Right click on the file and go to Copy.
- Right click on an empty place in the folder and select Paste. You should now have a new file named prefs_copy.
- Right click on the prefs_copy file and click Rename.
- Type the word user and press enter.
- Double-click the user.js file to open it. Select and Delete ALL of the contents, and replace the contents with the following:
// authenticate intranet sites
- Update “yoursite.com,anothersite.org” with the name or names of your SharePoint intranet site and Save the file.
