Not possible to do the same in 3.6.13.

Note: Inbetween steps 2 and 3 in comment 0, don't release the left mouse button before right clicking.

Ed,

This also occurs if I release the mouse between steps 2 and 3, like so:

2. Click and hold the left mouse button on the Back Button until you get the
previous tabs list.
2a. Release mouse button.
3. Right-click one of the tab entries.

Actually yes, you're right, you can release the left mouse button as long as you don't move downwards before doing so.

Bug 582485 - Remove history dropdown arrow behind back button r=gavin a=sdwilsh
http://hg.mozilla.org/mozilla-central/rev/664dc9adfcf5

Left clicking and holding the old dropdown (that existed prior to bug 582485) doesn't let you create the second context menu. Only the new implementation does.
