[Solved] Firefox asks intranet password

I have installed firefox and set it as my default browser. When my laptop is connected to my company LAN and when I happen to open an internal URL, firefox always prompts for password.

I did the following and now firefox does not ask for password.

1. Open the firefox tab and type in the address bar - about:config
   
2. Click on I'll be careful, I promise! button.
   
3. Find network.automatic-ntlm-auth.trusted-uris in the list
   
4. Type the internal website URLs as a comma separated string and click OK

Setup Firefox in Ubuntu 12.04

It was surprising to know that there is no direct way to install firefox in Ubuntu. No worries, I'm not a Windows user!
After I installed Ubuntu 12.04, I have installed firefox, in a not so direct way(double click a .deb, I meant). I'm listing below the steps to get the latest build of firefox setup.

1. Download firefox from www.mozilla.org
2. Extract the firefox-_____.tar.bz2 to a directory firefox
3. Run the following command in terminal, to move the directory into /opt/
   sudo mv firefox /opt/firefox
4. Using the following command, take a backup of the default firefox symbolic link in /usr/bin/ directory
   sudo mv /usr/bin/firefox /usr/bin/firefox_backup
5. Create a symbolic link in the /usr/bin/ directory that points to the newly downloaded firefox binary. Use the following command
   sudo ln -s /opt/firefox/firefox /usr/bin/firefox

The firefox browser is installed on the machine now. We need to do the sync setup, plugins setup for the firefox to be fully functional.

1. Open Tools > Setup Sync and follow instructions to complete the sync setup
2. Install Adobe Flash Player plugin. This is needed to play video files in youtube. Use the following command to install
   sudo apt-get install flashplugin-installer
3. After that install Adobe Flash Player, visit the url www.adobe.com/software/flash/about/ to ensure that the plugin is installed
