- reading the whitish bookmark names on the black background is very unconfortable
  - the separations bars between groups of ordered bookmarks become invisible
  - when navigating down the bookmark folders tree, a number of sub-carpets may open right or left of the cursor (it changes every time I go down any given path), and the superposition of black sub-carpet roll-down menus on already opened ones is basically painful to look at, let alone to read, because of the absence of borders for each individual sub-carbet menu.

On a dual boot machine (win-xp sp3 || lx-ubuntu 14.04 lts), I run Fx (respectively 30.0 and 29.0) with the Classic Theme Restorer 1.2.0 add-on. What I discribe below applies specifically to what happens in the Linux environment. As a point of reference, under Win-xp, the Fx bookmark roll-down menu background color is a nice shade of grey (perhaps a theme dependent color). Everything is fine. Under Lx ubuntu, the same roll-down menu is pitch black with no border. The result is: - reading the whitish bookmark names on the black background is very unconfortable - the separations bars between groups of ordered bookmarks become invisible - when navigating down the bookmark folders tree, a number of sub-carpets may open right or left of the cursor (it changes every time I go down any given path), and the superposition of black sub-carpet roll-down menus on already opened ones is basically painful to look at, let alone to read, because of the absence of borders for each individual sub-carbet menu. Is there something wrong in my user config under Linux (it is identical to that under Win) , and a way of fixing / tweaking it ? Cheers. -ced.
