Been using this add-on for years and it still works fine with v109.0 of Firefox. I use a custom Firefox style which eliminates the tab bar (instead relying on All Tabs Helper for navigating tabs via a pulldown list), so this add-on fills the need to quickly close a tab that I'm viewing. I wish we could change the color of the "X" icon, but that's not a deal-breaker.

Nice

Very nice add-on, thank you!

May your life be forever!

Please add middleclick action for unclose last closed tab.

Exactly what I was missing in Quantum, but couldn't find time to code it myself.
