Chrome, Edge, Brave, all have the "Close Other Tabs" option from a right click. However, Firefox does not. You have to right click, then hover over "Close Multiple Tabs" and then you can click "Close Other Tabs". This is a little thing that I use all the time. May I kindly ask you to consider surfacing this option on the top-most right-click menu? It would be a great improvement!!! Thanks for all the work on a great browser.
