Firefox – Change the close-button for tabs
Dec 18, 2008
There has been so many discussions about where to place the close-buttons for tabs that Mozilla has created a config key for this specific option.
To access the key, open a new tab, enter about:config then press enter. In the filter search for browser.tabs.closeButtons. Change this value according to your choice and the following table:
| Value | Button state |
| 0 | Close-button only on the active tab |
| 1 | Close-button on all tabs |
| 2 | No close-buttons |
| 3 | A closebutton at the end of the toolbar, not on the tabs |
