userContent.css

userContent.css is your go-to solution for blocking annoying ads in browsers like Firefox, Mozilla, Camino, and Safari. If you’re fed up with distracting ad images cluttering your browsing experience or even your email, this tool is perfect for you!

What is userContent.css?

This nifty little text file contains CSS rules that help control how web pages look. By using userContent.css, you can easily keep many of those pesky ads from popping up while you surf the web.

How Does It Work?

The best part? userContent.css works with any Gecko-based browser. This means it’s compatible with Firefox, Mozilla, Camino, and even Apple's Safari!

Installing userContent.css on Safari

If you're using Safari and want to give userContent.css a try, just save the file somewhere easy to find (we suggest ~Library/Safari). Then launch Safari and follow these steps:

• Go to the Preferences menu.


• Select the Advanced tab.


• In the Stylesheet popup menu, choose your new userContent.css file.

No need to restart Safari; it will automatically apply the stylesheet to all pages right away!

Where to Place userContent.css

You’ll need to put the userContent.css file in the chrome directory of your browser's user profile. Here’s where you can find that directory on Mac OS X:

• Firefox: home:Library:Application Support:Firefox:Profiles:profilename:randomstring.default:chrome:


• Mozila or Netscape: home:Library:Mozilla:Profiles:profilename:randomstring.slt:chrome:


• Camino: home:Library:Application Support:Camino:chrome:

Your browser will need a quick restart to pick up these styles. Once it’s back up, head over to your favorite websites and enjoy browsing without all those annoying ad images!
