I absolutly despite close buttons on tabs. They are nightmare. They take up screen space away from the tab. Their location is always moving around with the tab. Way to easy to hit when wanting to click on a tab in a hurry. you have to move the mouse to close more then one tab.
A fixes close button that kills the current tab is MUCH better. A single fixed locatin helps in preventing accidental hits. It offers the advantaged of utilizng muscle memory to locate the close button. It allows for rapid closing of several tabs if needed without moving the mouse in many cases. It saves screenspace by been just a single button instead of like 10 or more. In short the are worst idea for tabs possible. This message posted from opensolaris.org
