Looking for tab close add-on Rated 3 out of 5 stars

Is there *NO* add-on for SeaMonkey that adds a close button to each tab so one does not have to right-click and move cursor down to 'Close Tab'? I really like SeaMonkey and it is one of the main Internet browsers I use but I *do* miss that 'X' to close tabs!

This review is for a previous version of the add-on (0.3.1). 

not that i know of, instead of right clicking you can middle click on a tab to close it

edit: i just received an email with a link to an extension which adds the close tab X
