Have you tried reinstalling Norton, another user reported reinstalling worked.

No, I have not reinstalled anything yet. Today I will be doing a major backup with disc image etc. So I may try a reinstall after that . I have found a link to a Norton reinstaller. I will let the community know if that worked. I know this may sound over-cautious but I have the impression that Norton's reputation is not that great! I can survive without the toolbar but you also lose the reassuring safe web browsing functionality. By the way I had no problems with an old Win XP 3rd machine which runs the 3rd Norton licence. !! So I can browse with that. It's in the same room as the Win7 machine with problems. UPDATE:: Sept 01 11.00 GMT 3 hours later: Nope! Still no change. Norton reinstalled . Toolbar still not visible in Firefox. Add-ons still shows old incompatible version of toolbar still disabled (4.1.2) Maybe a reinstall of Firefox? 5 mins later. Oh dear.!!I just fired up internet explorer.!! Guess what? There is a Norton toolbar!!

30 mins later: YAY!! After a couple of Norton Live updates and reboots with firefox 23 shut down I now have the bloody toolbar!

Any advice for Firefox 24 update welcome!!

Thanks anyway.
