Close All Tabs To The Right by ceda

Tired of right-clicking and navigating menus just to close tabs to the right? This lightweight extension adds a keyboard shortcut and a toolbar button that instantly closes all tabs to the right of your currently active tab.
How it works:
• Press Alt+W or click the toolbar button
• All tabs to the right of your active tab are closed
• Your active tab stays open
• If there are no tabs to the right, nothing happens
The keyboard shortcut can be customized in Firefox: go to Add-ons (Ctrl+Shift+A) → gear icon → Manage Extension Shortcuts.
This extension is minimal by design — no settings page, no data collection, no background network requests. It does one thing and does it well.
