manually install firebug

To install Firebug manually you have to do it differently. There are two ways to run extensions manually:

1. Extract the XPI

  1. Download the XPI file that contains the extension
  2. Locate the ‘extensions’ folder within your profile (e.g. via Firefox menu > Help > Troubleshooting Information > Show Folder)
  3. Create a new folder within the ‘extensions’ folder and call it like the add-on’s id (for Firebug this is
  4. Extract the XPI into that folder

2. Get the sources from the git repository

A detailed description for how to do that can be found on the development setup description on the Firebug wiki. It’s similar to the description above with the addition that you’ll be able to always get the latest sources.

how to make firefox work in SSO


You can configure Firefox to use Kerberos for Single Sign-on. In order for this functionality to work correctly, you need to configure your web browser to send your Kerberos credentials to the appropriate KDC.The following section describes the configuration changes and other requirements to achieve this.
  1. In the address bar of Firefox, type about:config to display the list of current configuration options.
  2. In the Filter field, type negotiate to restrict the list of options.
  3. Double-click the network.negotiate-auth.trusted-uris entry to display the Enter string value dialog box.
  4. Enter the name of the domain against which you want to authenticate, for example,
  5. Repeat the above procedure for the network.negotiate-auth.delegation-uris entry, using the same domain.


    You can leave this value blank, as it allows Kerberos ticket passing, which is not required.
    If you do not see these two configuration options listed, your version of Firefox may be too old to support Negotiate authentication, and you should consider upgrading.

You now need to ensure that you have Kerberos tickets. In a command shell, type kinit to retrieve Kerberos tickets. To display the list of available tickets, type klist. The following shows an example output from these commands:
