Profile directory
From GreaseSpot
The profile directory refers to your Firefox User Profile. It is located at a different path, depending on your platform:
- Microsoft Windows
-
%APPDATA%\Mozilla\Firefox\Profiles\Random Value.default
or
%USERPROFILE%\AppData\Local\Mozilla\Firefox\Profiles\Random Value.default
Note: you may need to enable displaying hidden files to seeApplication Data, or type it into the address bar.
- Apple OS X
-
~/Library/Application Support/Firefox/Profiles/random value.profile name
Note: random value.profile name is sometimes "default.dcc" - Linux
-
~/.mozilla/firefox/random value.profile name
Above, random value will usually be something like "928za141", and profile name is usually "default" if you haven't created a new profile with another name.
