Remove new tab button from Firefox 3.1
Firefox 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 System | Path |
|---|---|
| Linux | ~/.mozilla/firefox/*.default |
| 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.
