Norton and IE9

I'm thinking of installing IE9 as it came up on my updates, but I want to check if it works satisfactorily with Norton. I have Windows Vista Home Premium and am  now using IE8. I read somewhere that it has its own security and I don't want a conflict with Norton 2011. Will I like it as well as IE8?  I read somewhere that someone lost his Favorites when he installed IE9 and that Menu was missing.
