R.I.P. this addon now that it's officially here

It's convenient. Thanks, author.

It doesn't work on my firefox 88.0!

Love it. If only I could re-order these 3 brilliant add-ons

Why isn't this feature built into Firefox already? This is amazing!

I was missing this feature that was avaliable in Vivaldi

exactly what I've looked for.

Super useful feature, not sure why it's not baked in by default.

10/10 will close tabs to the left again :thumbs_up:

Congratulations. Just what I needed

Works as advertised. Would buy again.

Firefox closes right hand tabs, and, luckily, you have this add on to close tabs on the left which does (bizarrely!) happen to be necessary sometimes!

要是原生支持就更好了.
