Remove or Move the close button

Move or remove the close tab button. Do you accidentally click on the close button of Firefox’s tabs? You can move them or remove them, again through about:config. Edit the preference for “browser.tabs.closeButtons”. Here are the meanings of each value:

• 0: Display a close button on the active tab only
• 1:(Default) Display close buttons on all tabs
• 2:Don’t display any close buttons
• 3:Display a single close button at the end of the tab bar (Firefox 1.x behavior)
