I'm on Mountain Lion 10.8.5 and have Dropbox 2.10.29 installed. For some reason I can't permanently remove the Dropbox button from the Finder toolbar.
I can remove it temporarily using
Customize Toolbar or Cmd+drag it from the toolbar, but as soon as I open a new Finder window it's back again.
If I quit Dropbox from the menubar and remove the button, the button stays gone even if I open another window. The moment I start Dropbox the button re-appears.
How can I permanently remove the button (pictured below on the right) from the Finder Toolbar?
I've contacted Dropbox, but I thought I would check if somebody here would have a solution in the mean time as well.
