We have released a compatibility update to bring Firefox 7.0 support to Norton AntiVirus/Norton Internet Security 2012 (19.1.1) and 2011 (18.6) and Norton 360 5.1. To get the update, simply run LiveUpdate from the Main User Interface of your Norton Product. A reboot will be required after the update has been applied. If you are unable to get the patch, here are a few steps you can take to download the patch:
- Run LiveUpdate continuously until it tells you that there are no updates available.
- Reboot your computer, and then run LiveUpdate. The update may have already been applied by Automatic LiveUpdate.
- Please check the Norton Update Center to ensure you're running the latest version of Norton Internet Security or Norton 360. Most customers with a subscription will be eligible for a free update to the latest version.
If you are unsure whether or not you've received the update, please check that the following file has been updated to the listed version:
