Does exactly what it says and does it very well.

Thank you so much for this.
It actually even starts working at some point before the site has completely finished loading.
I wish it was a built-in feature of Firefox.

This addon is very useful, can't live without it. Works quick and without a hitch. I know it's been said before but thanks again for developing a webextension version of back to close, I've been back to closing for years.

Works perfectly. Thanks!
