How to Access Advanced Settings and Information for Your Chrome or Firefox Browser

Both Firefox and Chrome have pages with information and advanced settings that are available from the address bar by entering “about:X”, where X stands for a variety of possibilities.  A list of the possible entries can be obtained in either browser by entering “about:about” in the address bar (without quotes and with no spaces). Below are capsule lists of the available items for the “about” function. Take a look at some of these and you will be surprised at the kind of information that can be found.

Since both Chrome and Firefox are updated frequently, this list is subject to change. The entries below apply to Chrome 36 and Firefox 31.

The list is tremendous. Only if you have elaborated what each term meant in a more simple way. Though its easy to decipher when you type each term in the search box, I'd love to have a tutorial. When I searched for Chrome advanced settings, I found your page first on Google. Cheers up!

There is some cool information there. The plugins was useful since i cant find how to get there besides clicking on the plugins link on this page.

This is an okay list, but for most users, it is useless. It would be nice if you could point us to some information to use these settings. I have used some config settings before, with instruction from this and other sites. Thanks for the past information you have given. Colin

I tried with Chrome, because I would like to change the print function. This did not work. Nothing interesting and/or nothing new also with about:config and about:settings

Great list of Firefox about: features. Thanks. Lots of info and choices therein. One question: Where are the various about: files kept so I can back them up?

Whoops, never mind. I found it, along with every other .js file on my computer. I guess that's a file extension that everyone uses.

I'm running Chrome 16 beta (using the beta channel for a long time without incident) and find this "about:" list quite useful. The info available here would take lots of web searches and various utility runs to determine the interesting and sometimes useful data presented.

I've had a look at a few of these in Chrome and although this info might be fascinating to the programmers at Google, it's of no interest to me as an end-user. What do you think I might do with any of this?
