It may be a breach of etiquette to ask regarding a forked version of Firefox, but I've had great success with it except for just one thing; sidebar tabs. I tried "Tree Style Tab" as well, but it behaves poorly. Tabcenter-redux is working great, but the darn toggle won't open the sidebar. I can get to the sidebar in other ways of course, but I'd really prefer the toggle.
