Of course it has! But some menu options could have been moved since "previous versions".

but where? Previously it was found by right-clicking on a tab and selecting it..

Now it's under right-clicking on a tab -> Close Multiple Tabs -> Close tabs to the right.

There's also an add-on which brings it back to the previous position: https://addons.mozilla.org/firefox/addon/close-tabs-right/

Hi 8sjy093xyhfs,

You can found it by following step:-

• Right click on tab.
• Choose Close Multiple tabs, then you will find sub menu where you can find close tabs to right option.

Now it's under right-clicking on a tab -> Close Multiple Tabs -> Close tabs to the right. There's also an add-on which brings it back to the previous position: https://addons.mozilla.org/firefox/addon/close-tabs-right/

Thanks to @TyDraniu and @Shashank Shekhar, I tried to select both answers as solving but it only allows one.
