I have seen that typing about:somekeywords in browsers address bar gives some information. What is this ? Why ? Do we have something similar for the Firefox, IE also ?
Example : Try below in chrome's address bar
about:histograms
It called "The about: URI Scheme".
It's a way for a browser to present 'about' style information.
And yes, we have it in all browsers. In a Mozilla based browser, try about:mozilla
.
yes. try about:blank
see this for original mozilla about: commands and entry on wikipedia
Those are browser pages used for several different functions. Yes, IE and Firefox both have them, as well.
Click here for some information about Chrome's about pages.
Just like "http:...", "ftp:.." and so on, the "about:..." directive represent a so called "schema", a keyword that identifies some protocol. In this case, the about schema is the protocol chrome (like any other major browsers) uses to access misc informations.
About uri scheme:
about:
is an internal URI scheme (also known as a "URL scheme" or, erroneously, "protocol") in various web browsers to display certain built-in functions. It is not an officially registered scheme, and has no standard syntax.
I simply love about:robots
