Unwanted URL bar movement Rated 5 out of 5 stars
In large icon mode clicking on the forward/back button produces a back and forth shift in the URL bar by a few pixels at the right end of the bar. Doesn't happen with small icons which btw defaults to the blue hover color.
I've had this behavior with many versions of Australis as well as different versions of Fx. Currently I'm on 21.0a1.
This is default behavior in newer versions of Firefox. I'll write up a custom user style to disable this feature. You can also add a space between the buttons and the address bar if it really bothers you (more than some weird space does). Thanks for reviewing!
