Other than the fact that no button appears at all, this is a wonderful extension.

Thank goodness for this add-on. The on ly thing I don't like about it is it hasn't been updated for HD monitors which causes it to be blurry. Not a biggie but it would be nice to have crisp and clear like all the other buttons.

Absolutely perfect. Just click icon and all tabs to the LEFT will disappear. Firefox foolishly did provide this function (only a close tabs to the right). Shame on Firefox, but this fixes it.

Would be more useful if it had keyboard shortcuts like the counterpart in Chrome. I mostly use them instead of clicking the buttons.

It works, but I'd rather have the control be when I click on the open tab option to close the left tabs, not a button on the bar

おぉ、復活していたのですか。ボタンごとにアドオンが分かれているというのは少々面倒ですが、さほど手間がかかるわけでなく些細なことです。以前と同様にタブのクローズ操作ができるようになって感謝しています。

Thank you very much for updating!

このために57へのアップデート待ちしてました有難うございます！！！
左側の閉じるメニューもお願いします。

These simple buttons are so great, I painfully missed them when Firefox Quantum was released. Thanks a million!
