Firefox 2 – Display Single Close Tab Button

Close Buttons on Tabs in Firefox 2.0

If you’re now using Firefox 2.0, you’ve probably already noticed that tabs now have close buttons by default, instead of having a single tab close button on the far right-hand side of the toolbar. If you preferred the older behaviour, simply navigate to the “about:config” page (type it in like a URL or webpage address), and find the section marked “browser.tabs.closebuttons”. Double-click on this entry, and set the value to 3 to display a single close button at the end of the tab strip (Firefox 1.x behavior).

Alternatively, you can set the value to 0 to display a close button on the active tab only, 1 to display close buttons on all tabs (Default), and set it to “2 to not display any close buttons at all.

A parting tip: To close the current tab using your keyboard, press CTRL+W. If you close a tab by mistake, just head to History > Recently Closed Tabs, and you can resume work from there (alternatively, you can use the arcane keyboard combo CTRL+SHIFT+T).

If you prefer using your mouse and want an even faster way about it – try the middle-mouse click (that’s typically a scroll button). When you click the scroll on any tab it instantly closes the tab for you. I have been using this method quite a bit lately. Though it seemed quite alien at first, I quickly got used to it and it’s now a major part of my Firefox 2 workflow.
