One of the things I like the most about my Firefox config is this tricky to hide bars and maximize content. Putting together the sources [1] [2] [3]:
- Go to
~/.mozilla/firefox/<profile>on Linux,~/Library/Application Support/Firefox/Profiles/<profile folder>or~/Library/Mozilla/Firefox/Profiles/<profile folder>on OSX,%appdata%\Mozilla\Firefox\Profiles\<profile folder>on Windows - Create directory chrome if it doesn't exist
- Create file
userChrome.cssinside if it doesn't exist. - Add this text to the file:
@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");
