I am trying to use the Custom Buttons addon to create the following two toolbar buttons. Bu I need the codes and I didn't get aid at the Custom Buttons official forum. Hope someone here could help. (1) Force links to open in new background tabs Click on this button and then everytime you open a link, it opens in a new background tab. Click on it again and then the original setting is restored. (2) After the current tab is closed, open the right tab Click on this button and then everytime you close a tab, the tab next to it on the right will be opened. Click on this button again and then the original setting is restored. Thank you in advance.
