Here is how the tabs overlap the Waterfox button on my Windows 7 machine. Notice also that the minimize, maximize and close buttons have a strange gap below them.
One of the images quoted below shows that the Firefox button is shorter than the Waterfox button. Perhaps the larger Waterfox button is pushing everything down, messing up the min/max/close buttons as well.
My previous version of Waterfox didn't have this problem. When I updated, this problem appeared immediately without me changing any settings. I also tried disabling all plugins and reinstalling Waterfox. I don't remember what version of Waterfox I was using before, but it was about 6 months old and hadn't been updated until today.

Re-download the installer, I updated some things.
Don't think he meant minimized, but specifically "not maximized", as in it's windowed, not full screen. However, maximizing does not fix the problem, but merely hides it because the tabs are no longer below the Waterfox button. On mine, when maximized, the strange gap below the min/max/close buttons is still there.

There they refer to people changing their appearance settings, like title bar size, etc. But I have not done this and Firefox 18 looks fine.

Perhaps this is the problem right here. The Waterfox button is too large for the space it's supposed to fill, forcing that space to enlarge and overlap.
