Pull out the hidden pages of Firefox Firefox browser

Many people have IE's startup page set to "About:blank" to speed up the start of IE, of course, Firefox also has a similar function, sorted from the Internet as follows:

About: With no parameters of the "about:" command to start Firefox will show Mozilla "about ..." information, followed by the help of the menu selection-about the effect, strictly speaking it is not a hidden page.

About:buildconfig Obviously, this will show the build platform configuration and parameters.

About:cache displays information and statistics about the user's disk cache, including the directory where the cache resides. Firefox, by default, does not allow users to view cached pages.

About:config There are many settings options, once the error browser settings will not work, so users should be careful to set.

About:plugins This parameter will display information on all plug-ins installed on Firefox.

About:credits shows a list of all the people who contribute to Firefox's development, and the user can vote.

About:mozilla strange thing happened, this will show "Mozilla book", but actually did not show any actual book.
