I have been using Tree style tabs for over 10 years. It is an indispensable tool.

With recent updates, the X to close a tab is now on the left and not the right and the > to expand a stacked tab is now on the left.

I'm not sure why the change, but it's confusing for legacy users. It would be nice to revert it, or at least give us an option. Thanks!

firefox should has this feature built in

Thank you so much for this last update. This is such an improvement !!

this is probably one of the best extensions I've used, with features that are useful, obvious & intuitive right out of the box.
I have a few extensions that I install on every browser, and this will be one of them

it should be preinstalled, way better than the usual tabs

多段タブがバージョンアップのたびに使えなくなるので見限り代替となるものを探していました。

please make it possible to hide the original firefox tabs
