Layering Issues and No Right-Click Menu

This may or may not be addressed elsewhere, but I wanted to let the devs know...I don't get a right-click menu in Firefox v19.  I have the All-In-One Gestures extension, if that matters.  (I didn't even know there was supposed to be a right click menu until I saw someone talking about it :oP)  Also, stacked images seem to get reordered.  I used Chrome to get the right-click menu that allows for reordering the items (is there no keyboard shortcut for this?) but when I exit the game and reopen, the items are in the wrong order.

Neith, could you please deactivate the All-In-One extension and see if that fixes the problem?  Regarding stacked images getting reorderded. Could you please take a screenshot right before you leave the game and another one when you return and it occurs? Also, when this occurs could you check your console and post any errors you find? - Gauss

I discovered I can gain the right-click menu even with All-In-One active by left clicking and holding, then right clicking.  As for the layering, I haven't been able to get it to happen again.

The stacked images issue should not occur again. A new z-layer update was just pushed to main. If you get the z-layer issue again please let us know. - Gauss
