FirefoxShell

The web browser is now becoming an OS.

There should be a shell for for it.
Imagine having a textbox at the bottom of firefox with a blinking
cursor next to '$' where user can type commands.
It should have all the functionalities like variables, environment
variables, loops, pipes, redirection along with commands.

It should at least support following commands:
1. echo $content
Displays the content in text format.

2. echo $url
shows url or current page.

3. lslinks
lists all the links in the page

4. open N
where,
N = 0, if you want to open the page in current window
N = 1, ................................new window
N = 2, ................................new tab

5. pwd
whould display the current location. For example
http://groups.yahoo.com/group/letideasflow/

6. cd
without an argument should take you to home page.
with "..", it should take you to one upper level
if pwd is "http://groups.yahoo.com", then "cd xyz" should take you to
"http://groups.yahoo.com/xyz"

It should also support: grep,sed,awk etc.

What do you say?
Am I running a high fever?
