These are the author's + settings. The author does NOT expect (or indeed want) end users to just run with it as is. + Use it as a comprehensive list, or as a template for your own. Extensive links and comments + have been added to help. Before using this user.js, if necessary, you should change, remove or + comment out with two forward slashes any preferences you're not happy with or not sure about. + The settings in this file (user.js) OVERWRITE the ones in your prefs (prefs.js - these are + accessed via about:config) when FF is started. See the required reading above. + +* BACKUP FIRST: + Backup your profile first, or even just the PREFS.JS. Go to your profile directory and copy + prefs.js, rename it (eg to prefs.js.backup). That way, if you have problems, to restore FF + to the state it was in beforehand, close FF, delete the prefs.js, rename your backup copy of + prefs back to prefs.js, RENAME the user.js so it doesn't overwrite everything again, then + start FF. IF you have any problems, you can also ask in the comments at ghacks. + +* PURPOSE: + This is not a "comprehensive" list of ALL things privacy/security (otherwise it would be huge) + It is more like a list of settings that generally differ from their defaults, and is aimed at + improving security and privacy, at making a "quieter" FF, and at reducing fingerprinting and + tracking, while allowing functionality.

If you are having issues search for + "WARNING:" in this document, especially the ones listed just below. + + This user.js uses the author's settings, so you need to check these EACH release because + the author prefers anonymity, security, and privacy over functionality [eg being able to + paste in Facebook, downloadable fonts, and other minor inconveniences].
