Very ergonomic, low on resource use. It manages to work with several hundreds of tabs while similar addons freeze. It boosted my efficiency a lot when used occasionally.

Exactly what I needed wtih a clean UI, thank you!

I've tried several similar extensions, but this is the most ideal.

① There is no annoying notification.

② Insanely light

③ I can check which tab to close.

④ The pin tab remains as it is.

the best.

Simple, handy and efficient. Totally fulfills my needs. Thanks !

Works great, and has a nice interface.

It's Great! It's helpful for I want to close the same hostname tabs
but can like tabcloser?
