Chrome registration failed

Chrome registration is something each Firefox add-on must do to work in Firefox. While some add-ons come with the appropriate chrome.manifest file, other add-ons rely on chrome.manifest being automatically generated when you start Firefox.

Chrome registration failure can occur when an add-on has come bundled with Firefox and you don't have system rights to edit files where Firefox is installed. (Thus chrome.manifest cannot be generated.)

To prevent this error from happening again, you need your system administrator to log on with an administrator account, and run Firefox at least once.

If that isn't an option, you can disable the offending add-on.
