I was able to reproduce this myself on Windows, it's easy and you can move rather slowly and surprisingly still see the effect.

Can't reproduce with firefox-30.0.en-US.linux64 or 29.0.1.

This must be a duplicate, see:
* bug 997681
* bug 1001362
* bug 1015756
* bug 1019615

After reviewing those bugs, I don't think this isn't a dupe of any of them, and I have reproduced on two alternate linux systems (Arch and Ubuntu), I can follow-up with sysinfo and moz user agent as required.

The closest bug is 1015756 as it may be related to the timing of the close animation, but ultimately this is a different problem as the issue here is the tab 'clicked' needs to be tracked instead of the tab under the cursor at the time the middle-click is actually processed.

Works for me on Firefox 43 and Nightly 46. 
@Reporter,are you still experiencing the issue on latest Firefox versions?

Is the same effect for 'Mozilla Firefox 43.0' on Ubuntu.

Thanks for responding. I assigned this to Firefox: Tabbed Browser so people with more experience on this matter to be involved.
