move 2711 to 2600s
2711 is about web extension data and does not fit in the 2700s is all about websites' persistent data, i.e items that sanitizing and Storage Manager deal with. Dumping in 2600's which is getting a revamp later

 A `user.js` is a configuration file that can control hundreds of Firefox settings. For a more technical breakdown and explanation, you can read more on the [overview](https://github.com/ghacksuserjs/ghacks-user.js/wiki/1.1-Overview) wiki page.

 ### ![](https://github.com/ghacksuserjs/ghacks-user.js/blob/master/wikipiki/bullet01.png) ghacks user.js
-The [ghacks user.js](https://github.com/ghacksuserjs/ghacks-user.js/blob/master/user.js) is a template, which, as provided, aims (![](https://github.com/ghacksuserjs/ghacks-user.js/blob/master/wikipiki/exclamation.png) with [extensions](https://github.com/ghacksuserjs/ghacks-user.js/wiki/Appendix-B:-Extensions) <sup>1</sup> ) to provide as much privacy and enhanced security as possible, and to reduce tracking and fingerprinting as much as possible - while minimizing any loss of functionality and breakage (but it will happen).
+The `ghacks user.js` is a **template**, which, as provided, aims to provide as much privacy and enhanced security as possible, and to reduce tracking and fingerprinting as much as possible - while minimizing any loss of functionality and breakage (but it will happen).

-We aim to INFORM and give you CHOICES. No one size fits all, so customize it! And not all sites have the same requirements, so use [profiles](https://github.com/ghacksuserjs/ghacks-user.js/wiki/2.3-Concurrent-Profiles) with custom versions. We won't set you wrong.
+Everyone, experts included, should at least read the [implementation](https://github.com/ghacksuserjs/ghacks-user.js/wiki/1.3-Implementation) wiki page, as it contains important information regarding a few `ghacks user.js` settings.

-INFORMATION IS POWER. So you can make informed decisions to better protect yourself online, we aim to be:
-
-* Accessible (provide information and simpler, less-technical descriptions if possible)
-* Accountable (provide reputable references/sources, [test sites](https://github.com/ghacksuserjs/ghacks-user.js/wiki/Appendix-C:-Test-Sites), dispel bad advice)
-* Change trackable (yay! we're on github now, with commits)
-* Compatible (including a [deprecated section](https://github.com/ghacksuserjs/ghacks-user.js/issues/123), [releases](https://github.com/ghacksuserjs/ghacks-user.js/releases))
-* Comprehensive (including enforcing defaults and future-proofing)
-* Current and up-to-date with stable (including [changelogs](https://github.com/ghacksuserjs/ghacks-user.js/search?q=label%3Achangelog&type=Issues&utf8=%E2%9C%93))
-* Detailed (preference versioning, hidden preference information, explanations, and more)
-* Easy to use and discuss (sections, sub-sections, numbering)
-* Helpful (including a [wiki](https://github.com/ghacksuserjs/ghacks-user.js/wiki) with features such as [extensions](https://github.com/ghacksuserjs/ghacks-user.js/wiki/Appendix-B:-Extensions), [user scripts](https://github.com/ghacksuserjs/ghacks-user.js/wiki/3.1-User-Scripts), [references](https://github.com/ghacksuserjs/ghacks-user.js/wiki/Appendix-D:-References) and more)
-* Innovative (formatting, special tags, and future plans such as branches)
-
-### ![](https://github.com/ghacksuserjs/ghacks-user.js/blob/master/wikipiki/bullet01.png) usage
-Everyone, experts included, should at least read the [implementation](https://github.com/ghacksuserjs/ghacks-user.js/wiki/1.3-Implementation) wiki page, as it contains important information regarding a few default settings we use. The rest of the [wiki](https://github.com/ghacksuserjs/ghacks-user.js/wiki) is helpful as well.

+* [12bytes](http://12bytes.org/tech/firefox/firefoxgecko-configuration-guide-for-privacy-and-performance-buffs)
   * The 12bytes article now uses this user.js and supplements it with an additonal JS hosted right [here](https://github.com/atomGit/Firefox-user.js) at github

-<sup>1</sup> ![](https://github.com/ghacksuserjs/ghacks-user.js/blob/master/wikipiki/exclamation.png) Important: We HIGHLY recommend using uBlock Origin, uMatrix and a cookie extension. Section 0400, if modified, allows Tracking Protection and Safe Browsing to be disabled. Do this at your own risk. See the [implementation](https://github.com/ghacksuserjs/ghacks-user.js/wiki/1.3-Implementation) wiki page for more.

With Martin Brinkmann's blessing, it will keep the ghacks name.
