OS X right click question

[Ender17]

How do I get a right click context menu pop up from a toolbar bookmark folder in Firefox on OS X? I swear I've done it before by just doing a double trackpad tap (set to right click) but now it does nothing.

tried a new firefox profile, tried safari, tried turning off the two tap for right click, tried uninstalling MultiClutch
nothing works

Here is a picture from my Windows machine to illustrate what I want.

you cant. but if you go to your Bookmark collection in Safari by pressing the book icon on the left you can right click bookmark links. if you want to open the link in a new tab simply hold the command key and then click it.
