i'm having this issue since ever, i think, i never had the options for private browsing on taskbar's context menu, i always missed that feature on iron, since i had it on firefox (i use them both) thing is yesterday i installed iron on a friend pc and i get a surprise since i saw that in fact that feature do exist, since when, well i don't know, i uninstalled my iron deleted all files that may remain on the hd, just to make a clean install and still it's the same, i can't get that feature, so i wonder if somebody can tell something about this. i already googled it but i found nothing.
p.s. excuse my bad bad bad english. i will attach 2 images so you can get an idea of what i'm talking about
