Hi joebike2:
You are soooo screwed.
I've actually never heard of PapauZ's instructions here not working unless there was something seriously wrong with the Firefox installation. Given that the Norton extensions stopped working in FF6 back when you still had NIS 2010, it's beginning to look more like a problem with the upgrade to FF 6.0.2 rather than with NIS 2012. Maybe a clean re-install of Firefox using the "Remove my Firefox personal data and customizations" option is in order.
If creating a new Firefox profile doesn't work now as SendOfJive suggested in message # 7, I'm not sure what solution other than a clean re-install of Firefox would work, besides just waiting for a few days to see if LiveUpdate finally delivers the patch for the FF6-compatible Norton extensions. Some NIS 2011 users have actually reported in this thread here that the Norton Toolbar just mysteriously reappeared a few days after re-installing NIS.
RichD posted some information about the Norton Removal Tool here that says in part:
The Norton Removal Tool should remove all of the Norton executable files, like .exe, .dll, .sys files, etc. However, the Removal Tool will not remove all files. The ones that remain should only be static, inert files like log files, text files, readme files, history files, .dat files, etc. These files do not really need to be removed because they are essentially inert and will not conflict with your subsequent installation of any new antivirus product. If you want to go ahead and manually delete them, you could, but it may not really be necessary.
I suppose it's remotely possible that one of these files is interfering with the delivery of the LiveUpdate patch. If you're really desperate and don't want to wait a few days to see if the problems resolves itself, you could try deleting all the residual files in C:\Program Files\Norton Internet Security after running the Norton Removal Tool in Step 7 of PapauZ's instructions. However, there might still be a few hidden files in your C:\Users\<yourusername>\AppData folder related to Symantec/Norton that would be a lot harder to scrub off your hard drive.
You'll have to take all this with a grain of salt, since I still have NIS 2011 and don't know how difficult it is to get the Firefox 6 extensions working with NIS 2012.
And just FYI, I noticed that my screenshots in a previous post aren't displaying correctly now. This happens every once in while, and they usually re-appear after a few hours.
