On Ubuntu 10.10 I started a 2nd instance of Firefox using the command:
$ firefox -ProfileManager -no-remote &
Created a new profile and everything works smoothly except for the fact that this instance of FF does not obey by GTK2 customizations that I have placed in ~/.gtkrc-2.0
Moreover, only SOME of the customizations are not obeyed. For example, the vertical scrollbars are supposed to be on the left, but they are on the right. The scrollbar arrows are together (Mac-like) as specified, so is the scrollbar width.
The first instance obeys all customizations with scrollbars on the left. Any ideas?
