Using the about command in firefox, you can view these three important sources of information. Every firefox geek should be familiar with the use of these commands.

Firefox uses an about command system that allows you access to a lot of useful information. Here is an introduction to the three most useful about commands.

To perform one of these commands, just type the text into the address bar and hit ENTER like you would any URL.

about:plugins

This command will list all currently installed plugins in your firefox installation. Curious about which version of flash you have installed into firefox? Wondering what version of adobe reader you are using? This command will give you your answers.

This command will show you a synopsis of firefox's cache. You can also easily browse the files stored in your cache from here. This also displays your cache statistics and the directory location of cache directory.

You can focus on your firefox memory cache by using the following command...
about:cache?device=memory

You can view your cache stored to disk by using this command...
about:cache?device=disk

This starts the GUI for tweaking your advanced configuration options and user preferences.
