I just switched from Firefox brower and a thing that i miss is the feature to personalized you toolbar but specially the "Density" of the toolbar, because i use a laptop sometimes webpages makes one feel a little claustophobic, and the lack of vertical space makes me avoid using bookmark bars, i think would be lovely to be able to decrease the size.

So i started using GX recently and while getting used to it i saw that in this particular site(Streamtape.com), where you can upload/download videos, the rigth-click contextual menu does not appear when trying to save a vid, had to open a different browser for it.
