“About” Commands in Firefox
Did you know typing “about: ” plus another word in Flock will allow you to view special configuration information of the browser–some of which you can actually tweak and customize?
To try it, type “about: ” to show standard and version information. Make an effort “about: cache” to view the browser cache, or “about: plugins” to show plugin information. If you are feeling adventurous, try “about: config” to show the browser configuration configurations (but be careful when changing settings here). And for some extra fun, type “about: Mozilla” to see special things provided by the developers.
