I found a solution: renaming .Xresoources as .Xresources. Sorry for the noise
Thanks Skomoroh, the .Xresources solution worked for me for PySolFC 2.x. It's not working for me for PysolFC 3.0.0 (built in a venv on Debian 12 Bookworm). I will post again here if I find a solution

Point #3, in case you want to sort the bookmarks, text can be prepared for editing ~/.config/xfe/xferc by grep ^BOOKMARK ~/.config/xfe/xferc | sed 's/.*=//' | sort | nl | sed -E 's/ *([[:digit:]]*)[[:space:]]*(.*)/BOOKMARK\1=\2/'
+1. I worked around the full path bookmarks by creating a ~/0_shortcuts directory and populating it with symlinks
