Great! Rated 5 out of 5 stars
By far the most fun extension that I have used. This is NOT a slow tab changing extension - but if you have some lame system that you haven't defragged in ages and requires other normal maintenance that the rest of us take for granted, then it will be slow.
Mine changes tabs lightning fast, saw it on a mate's system ? - very slow. Why not ask around first guys, before slamming into good extensions like this one?...just a thought.
