let me know how it goes

You may need to update to a 2012 version of NIS to get Firefox 8 compatibility.

I use Norton 360 as well and had to enable the two Norton add-ons (see below) when I upgraded to Firefox 8.0:

• Norton Toolbar 2011.7.3.6; and
• Symantec IPS 3.2.

In your case as well, since you've used it before, the add-ons may still be installed, you just need to enable them, like I had to do. Firefox 8.0 automatically disables add-ons.

To see if the above add-ons are still installed, you can:

• go to \Firefox\Add-ons;
• click on Extensions;

...and you should find them there. If not, you will have to install them. You can use the links that Swarnava and the-edmeister have provided above.

Thanks! I did what you suggested and my Norton Toolbar is again active and the Auto Fill feature is working again. Thanks for your help!

I had the same problem before, but i figured it out. This answer might be a bit late now....

           1. Open the Norton program.
           2. Scroll under PC protection and select Run Live Update
           3. Repeat step 2 until there isn't anymore updates available.
           4. Restart the PC
           5. Open Firefox browser
           6. If the toolbar isn't there, press Ctrl+shift+A
           7. Under extensions enable the Norton toolbar.

Thanks for your reply, Pandy_Yang. The problem was resolved - everything is working okay.
