I thought it was broken in all of android-chromebook, but then I noticed I can long-press to collapse groups in Aggregator. but both in firefox itself and the embedded firefox viewer Aggregator uses, long-press and right-click do nooothing... except on the url bar. :/ this means I can't get contextmenus on links or images. sometimes the punchline to a comic is in that contextmenu. also I can't install the linux version of firefox on this chromebook, because it's cheap junk with a ridiculously small hard drive, so I'm stuck with just android apps (and only a few of them) until I can get a new one. I also have the touchpad-scroll-selects-text-instead bug, but I got around that by buying a mouse; the scroll *wheel* works.
