Change user js

You can make firefox fully-suited to your needs and for the maximum security, privacy, usability and performance without very much tweaking by changing the user js in your browser profile.

Firefox profiles are located by default in ~/.mozilla/firefox/ in Linux and %APPDATA%\Mozilla\Firefox\Profiles\ in Windows.

• Create a new Firefox profile or use an existing one and move to the profile directory. You can navigate to about:profiles and find the location for your current profile's root directory as well as find the option to create a new profile.
• If you want to try this out, you can go with creating a new profile.
• Copy user.js to your profile's root directory test it out for sometime and make the required changes in your original profile.
• For changing some prefs you can create a new file in profile's Root Directory, user-overrides.js and fill it with the prefs you want to override. Now, append the content at the end of user.js file. You can download from here.
• Done! Happy browsing.

The user.js file is taken from various other preexisting projects like arkenfox, betterfox and other projects and modified to suite the needs of a normal user.

Custom UserChrome (Browser Styling)

If you also want to change the appearance of Firefox, you can try searching for some userchrome projects on GitHub or elsewhere and giving them a try. The chrome/ folder in this repo contains a minimal userChrome.css that works with the firefox-csshacks styles — see the section below for setup instructions.

Using firefox-csshacks

You can also use the firefox-csshacks repo for a wide variety of CSS styles. To set it up alongside this config:

1. Open a terminal and cd into your Firefox profile folder (see the "Change user js" section above for the profile location).

2. If you already have a chrome folder, rename it before cloning. After cloning, copy the contents of the old folder into the new chrome folder.

3. Clone the repository into the chrome folder:

   git clone https://github.com/MrOtherGuy/firefox-csshacks.git chrome
   

4. (Optional) Copy userChrome_example.css to userChrome.css and userContent_example.css to userContent.css inside the chrome folder.

5. @import individual style files into your userChrome.css. All @import statements must be placed before anything else in the file. Check userChrome_example.css for how it uses @import.

6. Restart Firefox for the changes to take effect.

Afterwards, run git pull inside the chrome folder to update to the latest styles. git pull will not overwrite your userChrome.css or userContent.css, so you can safely add custom rules to those files.
