Excellent! Rated 5 out of 5 stars
This is excellent! I tried several other vertical tab addons, and this is the only one that lets me resize the width of the tab list panel! It has the option to create a tree from tabs - that way, if you open a link from a certain tab, its link goes into that tab's subtree. Great! This helps me keep organized. With a widescreen monitor, you get your vertical space back in your window. Thank you!This review is for a previous version of the add-on (0.14.2012081101).
