Hello Larrey, Norton Toolbar: 2013.4.2.2, see : http://community.norton.com/t5/Norton-Toolbar-Norton-Identity/Firefox-23-Support-for-Norton-Toolbar/td-p/1001655

thank you

Some users reported that you may have to run live update multiple times for it to update.

No Norton Toolbar yet! Re-stalled Firefox, updated Norton 360 many many times. No luck.

I suspect this is the problem but so far have not been able to get Norton to show me how to get there recent Norton Toolbar update.

My Firefox extension for Norton Toolbar is 2013.4.1.2 and Norton tells me they have updated it to Norton Toolbar 2013.4.2.2

If anyone knows how to get Norton's Toolbar version 2013.4.2.2 to update my Norton 360 I believe this will fix my problem????

Finally solved my problem. I had to un-install and re-install Norton 360 and when I updated and rebooted I had the latest Norton Toolbar, v2012.4.2.2

For some reason before the re-install of Norton 360 my Norton Toolbar would not update to the latest version. Norton Toolbar v2012.4.1.2 is not compatible with Firefox v23.0.1

At least now I have my Norton Toolbar with Firefox.

Great, mark solved YOUR latest reply to help others with same problem.

thank you

Corrected Post, should have said v2013 instead of v2012, sorry.
