Missing Norton Extension for Firefox 11 (using Norton Internet Security 2012)

It's my first time here in the Norton forums and I want to seek help regarding my issue. I just bought Norton Internet Security 2012 yesterday as my previous installation (Norton Internet Security 2011) was about to expire within 3 days. I uninstalled my previous version and installed the 2012 version using the CD that came with the packaging. After successful install, I noticed that my Firefox 11 browser is lacking the Norton Extension but my Google Chrome (17.0.963.83) doesn't lack it.

 

So I reinstalled my Firefox 11 browser after uninstalling it and restarted the computer. After doing so, the Norton Extension is still missing in my Firefox so I did as what I've read on other posts where I have done a couple of LiveUpdate until there is nothing left to update with, then restarted my computer. But still after doing so, the extension is still missing.

 

I tried uninstalling the Firefox 11 and installed the Firefox 10.0.2, done some few LiveUpdates and restarted the computer but still got no luck. I removed the Firefox 10.0.2 and installed the 11 again, but this time, I reinstalled my NIS 2012 from the CD (but this time while connected to the Internet so it was downloading) and did some LiveUpdates until necessary but still no luck with it. I already did what the Norton Removal Tool instructed and removed the NIS 2012 again and downloaded the one from my Norton Online Account and used the download manager. After installing, I did some LiveUpdates again until necessary but still, I don't have the Firefox 11 Norton Extension while my Google Chrome browser has it.

 

I can't think of anything else just to enable the extension on Firefox 11 so I came here out of frustration to seek help. Thanks in advance!

 

PS. I'm on NIS 2012 19.6.2.10 everytime I'm finished doing the necessary number of LiveUpdate
