Weird tab automatically opens
Sometimes when I go to a site with social networking buttons (i.e. FaceBook, Twitter, Google+), a weird new tab opens up with a small button on the upper right corner. I suspect that it's an add-on problem; but because it occurs randomly, I cannot single out which add-on causes this weird behavior, nor can I provide an snapshot attachment immediately.
Note, The extensions Download Helper, DownThemAll, Fullscreen Homestarruner, TabMixPlus, and TACO were disabled at one point when this issue occurred.
If anyone reading this does not have this problem, please list the add-ons you use that are also on the Troubleshooting Information list so that I can rule them out.

Turns out it opens in a new tab because tabmixplus, but even when I change the settings, it can still appear whether it's in the current tab or in a new window.
