Remove new tab button from Firefox 3.1

Firefox LogoFirefox 3.1 introduced a new button to create tabs. This button is useful for people who don't know or can't remember the shortcuts. For me it's just cluttering the interface. ;) So here's how to remove that button:

First you'll have to find your userChrome.css. It's depends on your operating system and username. The first thing you have to do is to find your firefox profile folder:

Operating SystemPath
Windows (XP)C:\Documents and Settings\<user name>\Application Data\Mozilla\Firefox\Profiles\<something>.default

In case you can't find your profile folder there is an Article in Mozillas wiki about this.

In your profile folder there is a folder called chrome. In there you should find a file called userChrome.css. If it doesn't exist just create it. Finally add the following to your userChrome.css

.tabs-newtab-button {display:none !important;}

That's it.
