Problems with TabMixPlus and Firefox 17 Rated 5 out of 5 stars

This is the one of best addons ever, but I found at least 2 problems:
Sometime Firefox opens 2-3 links instead of one; Addons configutation menu is not working from main menu, only from about:addons.
Turning TabMixPlus resolves both problems.

This review is for a previous version of the add-on (0.4.0.3).
