Hi, In case you don't know, it's possible to use multiples profile with firefox. To make things simple you can use a modified shortcut to a particular firefox profile. (one with full extension, private bookmark or ...) Just do a .bat ( or maybe a shortcut should work) with this line: start E:\FIREFOX_FOLDER\firefox.exe -profile E:\FIREFOX_FOLDER\DELUXE_PROFILE Where FIREFOX_FOLDER is the installation directory, and DELUXE_PROFILE is the Profile Directory name. This way you can also make firefox like permanent. I mean even after reinstalling windows your profile will be intact if set to another partition. PS: to create profile you need to type this in RUN: firefox -profilemanager
