Could you please make your sync function work properly?

It would be nice if the sync function actually synced something other than just my bookmarks and my browsing history between my Firefox installations. I mean, I checked all the boxes, so theoretically it should...but no...it never does. Toolbars don't sync -- I know, for some reason that's "by design" (or laziness?) -- Settings don't really sync much (maybe a few do when the moons of Jupiter and Uranus are in perfect alignment).

Could you maybe consider syncing the various exception lists in the Settings?
