Make sure you check the changelog that is included in the download as it lists changes made in recent versions. Expect future versions to be less frequent, as the magnificent Pants (who is this guy? is he a wizard?) has decided to take charge of all changes, and will let the comments build up for at least a few days at a time. Please Note: Always use the latest download, as the many changes may get out of sync with what's on display in the article. You can download the most recent version of the list with a click on the following link:Īlternatively, you may load a custom HTML version of the list: User.js Light or User.js Dark, and load the changelog directly as well.

This means that the changes remain even if you delete it afterwards. Why backup prefs.js prior to this? Because any user.js preference that is legitimate is written to prefs.js when you place the user.js file in the profile folder. Copy the user.js file into the root of the profile folder.Click the show folder link under application basics to open the profile folder on the computer system.Type about:support in the Firefox address bar.Make sure you save it as a user.js file in the end. You may edit the list in any plain text editor, and use comment syntax // at the beginning of each line to block a preference from being set. I'd like to thank Ghacks' reader Pants for creating the list and giving me permission to publish it here on the site. Jump to comments for version 0.11 of the list.Jump to comments for version 0.10 of the list.Subsequent articles:Â January 2016 update, July 2016 update, February 2017 update.Current version: 0.11, published February 10, 2017, Firefox 51 is stable.There may be new features and new preferences as well, and the idea of this guide is to get a discussion going that improves this list on a continuous basis. Firefox is updated regularly and preferences may change because of this. The following list is a work in progress.

This can be done on the about:config page, or by placing a user.js file in the profile directory of the Firefox user. Firefox users find some of those options listed in the graphical user interface, but full control over the browser is only granted if changes are made to the browser's configuration. Mozilla Firefox is without doubt the web browser that gives the most control to users in regards to privacy and security.
