Where is middle-click on tab bar to undo closed tabs in Firefox 4?
In Firefox 3.x if you closed a tab and then middle clicked on an empty space in the tab bar, it would undo the most recently closed tab. Firefox 4 no longer has this feature.
I found an Add-on that replaces this feature ("Middle click to go back") which unfortunately includes the additional "feature" of closing your current tab if you middle click on an empty space in a webpage. I thought I could get used to this, but sometimes I just miss a link and poof... there goes my current tab.

That wasn't a standard feature in Firefox 3.x versions. By default, a middle-click on the tab bar did nothing in Firefox 3.6.
Take a look at the Undo Closed Tabs Button extension here.

It has a button, a keyboard command, and a contextual menu entry for undoing a closed tab.
Or take a look at this AMO search for undo closed tabs extensions.

Thank you for pointing this out. I somehow forgot to reinstall Tab Mix Plus when I switched over from 3.x to 4. It was one of those undocumented features that Tab Mix Plus offered that I simply assumed was part of the genius that is Firefox.
