With the release of Firefox 3.5, comes some new features and some annoying ones.

One annoying feature is wasting un-necessary real estate to include a new tab button on the tab bar.

All the button does is add a new tab when clicked, which is really not needed since you already have three options to add another tab, with the easiest method by pressing CTRL+T on the keyboard (the other two ways are double clicking on an empty tab bar area or right clicking on the tab bar and selecting New Tab).

A fourth method is not needed (yet another reason why Firefox is bloated).

Fortunately Firefox is customizable and removing the tab button requires a simple fix.

Removing the tab button requires adding a line to the userChrome.css file in your Firefox profile folder.

• First you will need to navigate to your Firefox profile directory and look for the chrome folder.

On XP, navigate to: \Documents and Settings\[yourusername]\Application Data\Mozilla\Firefox\Profiles\[profile.default]\chrome

On Vista and Windows 7, navigate to: \Users\[yourusername]\AppData\Roaming\Mozilla\Firefox\Profiles\[profile.default]\chrome

If you had previously customize Firefox, more than likely you have an exisitng userChrome.css file already. If not, just create an empty file named userChrome.css

• Next, open the file using Notepad and add the following line:

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

NOTE: If you already had an exisitng file, then just add the line at the bottom of the file.

• When finished, save the file and close it.

• Then close and re-open Firefox.

If everything was done correctly, the tab button should now be gone from Firefox's tab bar.
