Firefox uses the chrome:// protocol to store internal schemas. This is used to keep track of the different Firefox features and how they are related. This helps Firefox to be more organized and easier to use.


Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites.

The Question

SuperUser reader ChocoDeveloper really wants to know what the deal is with Firefox and the “chrome://” schema:

It is a rather curious designation, no? It’s almost like finding out that the secret configuration menu on your new Ford truck has the password “Honda”. What’s the story?

When I want to configure an addon, for example Ghostery, the tab shows a URL like this one:

chrome://ghostery/content/options.html

What does it mean? Does it have something to do with the Chrome browser?

The Answer

SuperUser contributor Mark Henderson clears things right up:
