A must have for a widescreen Rated 5 out of 5 stars
I don't know where I can make a feature request but the only thing I would change would be the ability to put the scroll bar on the right of the column. But usually, if the scroll bar appears, I use it as a hint to close some tabs!
Thanks for the immediate feedback. Solution duly implemented! :-)
Go to "about:config" and turn the preference "extensions.treestyletab.tabbar.invertScrollbar" to "false", then you'll see the scrollbar on the right even if you put the sidebar on the left.
