Tabs Don't Open Rated 1 out of 5 stars

I've been trying to find what's causing my tabs to hang. Saw that FFL has been upgraded, downloaded the current version. After restarting, windows stopped opening. Tabs had the url, but page remained blank, icon spinning, but not opening. Restarted twice, same thing. Once I disabled the upgraded FFL, the problem stopped. sorry for me and you about this problem.
