Here I re-post the content of the working version of the file:/* Change cursor for links that open in new window */:link[target=_blank], :visited[target=_blank],:link[target=_new], :visited[target=_new] {cursor: help;}The file is in my Win XP system as C:\Documents and Settings\<my_username>\Application Data\Mozilla\Firefox\Profiles\4bvayeer.default\chrome\userContent.cssNow, what I consistently failed to do, is to replace the cursor type from 'help' to using my own custom cursor file, by writing:cursor: url("some_valid_path_name_of_cursor_file");It just didn't work for me. If anyone manages to work this out, I'll be glad to get the details, and may be undestand what I am missing...
