userChrome.css

Since people have been having trouble creating their userChrome.css files I’ve decided to include this generator to do it for you. Simply fill in the form and save the file as userChrome.css in the chrome folder of your profile.

You may notice some commented out entries and this is deliberate so you can easily edit it later. Of course, you can use the generator again and save over the file, too.

If you don’t know where your profile is, see Mozilla’s instructions on locating your profile.

This is designed for new userChrome.css files and if you already have a userChrome.css there are instructions and code in the FAQ so you don’t have to overwrite your existing file.

Please note that this creates an English userChrome.css.
