Norton Toolbar won't work with Firefox version 41
This article is no longer maintained, so its content might be out of date.
Starting with version 41, Firefox has stopped supporting an old and fairly unstable technology called "Binary XPCOM" used by a small number of add-on developers. Mozilla has encouraged developers to update their add-ons in order to stay safe and compatible with the latest versions of Firefox (see the Mozilla blog post here and also our article Add-on signing in Firefox).
The current Norton Toolbar is temporarily not fully functional with Firefox until Norton releases a major upgrade. Norton's planning is announced on their forum including Norton's initial announcement and latest status updates).
Steps you can take:
- The standalone Norton application will continue to work without the toolbar. Use the features within the Norton application and if necessary uninstall the toolbar. Reinstall it when Norton releases a fix.
- Continue using the latest version of Firefox for the most stability and security. Do not use an older version of Firefox.
- Identity Safe users: Use Identity Safe directly in your Norton product, or visit https://identitysafe.norton.com/ in a new tab. From your Norton product or the Identity Safe site, you can view your logins and copy/paste your usernames and passwords. You can also access your address and wallet items.
