Aurora 17.0a2 work-around Rated 4 out of 5 stars
For those who cannot open the 'addon' page in Firefox Aurora 17.0a2 with Tab Mix Plus enabled, make sure to open the Add-Ons page in the very first tab, then it'll work.
Now as for what opens multiple tabs whenever I click an external link, that's for me to figure out. ;)
