This bug is specifically about middle-clicking or modifier-clicking the actual button, not about what happens if you use the keyboard shortcut, or what happens if you click the button with the left mouse button without using any modifier keys on the keyboard, and this bug is specific to Firefox.

If you want to change keyboard behaviour, or want to see a change in seamonkey, or the *specific* changes I just outlined don't work for you (check in a clean profile to make sure add-ons like tabmixplus aren't changing the behaviour), file a new bug. Commenting here will not help.
