Where does Mozilla profile located?


On Windows the profile data is per default located in:

Mozilla SeaMonkey

%APPDATA%\Mozilla\Profiles\[profile name]\[random string].slt\

On a English Windows 2000/XP that’s normally:

c:\Documents and Settings\[Windows Login Name]\Application Data\Mozilla\Profiles\[profile name]\[random string].slt\

Mozilla Firefox

%APPDATA%\Mozilla\Firefox\Profiles\[profile name]\

On a English Windows 2000/XP that’s normally:

c:\Documents and Settings\[Windows Login Name]\Application Data\Mozilla\Firefox\Profiles\[profile name]\

Mac OS

On Macintosh the profile data is located in For Mac OS 9:

system disk::Documents::Mozilla::Profiles::[profile name]::[random string].slt

For Mac OS X:

Mozilla SeaMonkey

~/Library/Mozilla/Profiles/[profile name]/[random string].slt

Mozilla Firefox

~/Library/Application Support/Firefox/Profiles/[random string].default/


~/Library/Application Support/Camino/


On Linux the profile data is located in:

~/.mozilla/[Linux Login Name]/[randowm string].slt/

What is the [random string].slt all about?

As an extra security measure Mozilla adds a random string to the path of the profile. This makes it a bit harder for vira/etc to obtain the path of the profile. For more information see bug 56002.
