I'm not sure whether it's OK to write a review based on suspicion - but I'll go ahead with it anyway and I'm happy to be proved wrong. I have been using this on Firefox for about three months now. In the options panel there is a button to disable the "show Facebook share option upon hijack alert". I clicked to disable this then it automatically turns itself back on. Then on the Firefox site, the developer has a picture of the extension but guess what? The thing it doesn't show is that it has that Facebook share button. I then checked WOT and found a review by "alexandergkelly" which makes me even more suspicious. Again - this review is based on suspicion and not necessarily facts. I'm happy to have someone here prove me wrong.
