Scripting

• On initial launch I'm seeing a 'checking compatibility of addons' screen.  It doesn't ask me to do anything and disappaers after a few seconds, but this worries me that it *might* complain about a plugin a user installed.
  Can this 'check' be avoided?
  Is it really doing anything? (eg: checking for blacklisted addons/extensions? etc)
  What's the worst that could happen here?
• In the registrry (HKLM\Software\Mozilla\Firefox\Extensions) I have two entries created by 2 other applications on the workstation each of which pointing to their respective extension/addon/plugin directory (e.g.: C:\Program Files\Application\some_directory).  When properly installed, one is listed as an Extension, the other a Plugin.  On the first launch after installation, I see two 'Install Add-on' tabs prompting me to approve each the installation.  Seeing as these extensions are allowed/trusted and required, I want Firefox to accept them without prompting the user.  Now, I'm aware of two key elements that largely govern this (and their subtle differences) but I can't seem to get this to work right:
  extensions.autoDisableScopes
  extensions.enabledScopes
  With the former set to 0 and the latter 15 I relaunch FF and while I don't get the tabs, when I go to test them, it doesn't work.  Furthermore, the Plugin is listed under Extensions which probably shoud not be.
  What am I doing wrong?
  How can I allow/trust/whitelist either specific add-ons, or add-ons within a specific location?
