Can't update IDSafe for FF18 no matter what

FF18.0.1 version extension page says that Norton Toolbar 2013.1.0.32 is not compatible with FF18. Toolbar is part of Norton 360 version 20.1.0.24 but no matter what I try, the toolbar stays that 2013.1.0.32 version and will not be updated to versions mentioned in this community that should be supported by FF. How can I update it to newer version. I DON'T WANT the solution Norton support usually offers for every problem... Uninstall, clean and reistall. I dont want to recreate all backup series etc. which can't be backuped
