Close Tabs to the Right
Full user review
"There's no need for this add-on"
It works as advertised, but...
There is no need for this add-on because the more functional Tabs Mix Plus add-on does exactly the same thing and a whole lot more. Not only can you place "Close tabs to right" in your tab context menu, you can place any of 20 different choices there. And Tab Mix Plus also lets you get your tabs so double-clicking on one closes it and double-clicking on an empty space in your tab bar opens a new tab. Even more valuable is the icon it provides for "Closed Tabs" that lets you reopen tabs you have closed - clicking on the icon opens the most recently closed tab - or you can use the drop down menu to pick a closed tab to reopen.
So while Close Tabs to the Right does work just fine, you're much better off with Tabs Mix Plus. Why clutter up FireFox with redundant add-ons?
