Used this add-on for some time now and found it really useful. However, I've had some serious performance problems (mainly with scrolling) with Firefox ever-since I've installed it. Firefox 46 finally came with the about:performance tool, which confirmed my suspicions - telify consistently comes up as slowing down my browser. After removing it everything went back to normal.
Sorry - it's a useful add-on, but until the performance problems are solved, I'm out.
