* README/IMPORTANT:
|
|
|
|
|
<font color=#ff3333>End users of this list/file are expected to know what they are doing. 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.</font> 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. There will be trade-offs and conflicts between these.
|
|
|
|
|
|
|
|
|
|
* COMMON ISSUES:
|
|
|
|
|
Some prefs will break some sites (it's inevitable). If you are having issues search for
|
|
|
|
|
"WARNING:" in this document, especially the ones listed just below.
|
|
|
|
|
|
|
|
|
|
<font color=#ff3333>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]. You have been warned.</font>

|
|
|

/*** 0400: QUIET FOX [PART 2]
|
|
|
|
|
This section has security & tracking protection implications vs privacy concerns.
|
|
|
|
|
These settings are geared up to make FF "quiet" & private. I am NOT advocating no protection.
|
|
|
|
|
If you turn these off, then by all means please use something superior, such as uBlock Origin.
|
|
|
|
|
<font color=#ff3333>IMPORTANT: This entire section is rather contentious. Safebrowsing is designed to protect
|
|
|
|
|
users from malicious sites. Tracking protection is designed to lessen the impact of third
|
|
|
|
|
parties on websites to reduce tracking and to speed up your browsing experience. These are
|
|
|
|
|
both very good features provided by Mozilla. They do rely on third parties: Google for
|
|
|
|
|
safebrowsing and Disconnect for tracking protection (someone has to provide the information).
|
|
|
|
|
Additionally, SSL Error Reporting helps makes the internet more secure for everyone.
|
|
|
|
|
If you do not understand the ramifications of disabling all of these, then it is advised that
|
|
|
|
|
you enable them by commenting out the preferences and saving the changes, and then in
|
|
|
|
|
about:config find each entry and right-click and reset the preference's value.</font> ***/
