I was figuring it might be interesting to see what kind of information this would provide. The moment I opened it, I realized how much I had underestimated it. This really does provide me with easy access to information that makes managing my high-tab-load life easier. Thank you! EDIT: ... and I was still underestimating how helpful this extensions is! It is solving a lot of problems for me - especially ones caused by the change in FF architecture. Thanks again!
Would love to see the total number of tabs displayed as a badge on the toolbar button, or at least when hovering over the button, display useful information such as the total tab count and number of loaded tabs (instead of simply reading "Tab Stats").
