Mozilla has released Firefox 10, and we have released a Norton Toolbar Compatibility Update to ensure compatibility between Firefox 10 and the Norton Toolbar. This update will be distributed to Norton 360 v5 via LiveUpdate.
For this update release, you will need to be running Norton 360 v5.2. We recommend that you run LiveUpdate and reboot until you are running this version, then run LiveUpdate again to receive this Norton Toolbar Compatibility Update.
To check if you've already received the update, launch Firefox and click Tools > Add- ons and select the Extensions tab. The versions for this compatibility update are as follows:
Norton 360 v5 (5.2) Norton Toolbar: 2011.7.5.2
Symantec Intrusion Prevention: 10.1.0.68 - 1
You may need to click on Enable in the Tools/Add-ons/Extensions section of Firefox, and then restart Firefox.
NOTE: If you are not able to update to Norton 360 v5.2, we recommend that you update to version 5.1 (Standard or Premium - free update with valid subscription) then run LiveUpdate to receive the 5.2 patch. Once that's installed, you can run LiveUpdate again to receive the Firefox 10 compatibility patch.
