Enabling the Debug menu without extensions
Mar 22, 08:38 pm
Many of the extensions listed here have options to enable Safari’s hidden ‘Debug’ menu, revealing useful features such as importing Mozilla bookmarks and spoofing other browsers user agents.
To enable this without using plugins, simply quit Safari, open Terminal and write:
defaults write com.apple.Safari IncludeDebugMenu 1
Press return, and then the Debug menu will appear the next time you start Safari.
