thanks to Mozilla Firefox the userChrome and the userContent .css files are saved
LONG LIFE to the chrome folder and to the UI Customization !

Styled+ for Firefox Browser is (Desktop\Windows all)

 - Multiprofiles\Multieditions: 

the setup is optimized for the Stable release and Beta editions, you can have the same or different Styles on multiple profiles. For the same or different Styles on different editions just use the Setup for the Developer or Nightly or if you use the Portable version just point to the proper Profile folder location during the installation .

- the port to other OS and\or devices will be very welcome -

- Independent: actually Mozilla is not officially supporting the resurrection of the chrome folder resources therefore my "add-in&out" -

IF YOU ALREADY USED SOME PERSONAL .CSS CODES:                                                                                                        the Operations Center (OPCEN) is organized in many separated sections and the Style Manager will became the base of your personal fun, you can save the changes on the fly with a mouse click , the new backup of the chrome folder will be saved in a separated folder (the attached date and time will prevent to overwrite them)

BEST OF ALL IF YOU WAS A COMPLETE THEMES (wanna be a full styles) DEVELOPER :                                                     you can mod and replace very easily every internal image and .css code, just respect the folders tree structure and send me the chrome folder, I will send you back the new compiled "yourStyle.exe" ready to share with all the FFlovers

                                         yes all the .css codes are clearly visible and editable !
