GrabCAD Groups Feedback

I noticed that it sometimes takes several presses of the back button (in Firefox) to get back to the main Groups page after I get into a discussion.
Based on my depth, I'd expect 2-3 clicks needed to get back, but I often need twice that number.
I'll test it out in some other browsers as well.

Chrome works as expected. Firefox requires multiple presses to back out. It is almost like it reloads the page multiple times. But, I also have some scripts and other stuff blocked in Firefox, so that could be breaking something.
