A usefull addon that not working very good. Tree style bar loses all tabs and I must close and open firefox many times, or close and open the bar, or disable and enable the addon. Can you fix it please? (Firefox developer v. 64)
so much better having tabs down the side than in a row that changes size and then has to scroll sideways. If only FF would let us remove them. TreeStyle Tab also lets me have nested tabs so it keeps threads together as I search and browse links.
