The Button is directly UNDER the Video! Rated 5 out of 5 stars
Worked immediately and correctly from the moment I installed it on 24 SEPT 2012.
Don't look for fancy knobs or gears -- just a simple DOWNLOAD button below the video. It contains one dropdown that offers a choice of formats.
Like the very best software, this tries to do exactly one thing and does it well. No beg-windows, no "see my other stuff" promos, no useless bonus options. Just a clean, simple, functional addon. I only hope the author will continue to update this excellent FF extension.
Note: Negative reviews are important. Intelligent ones can help the authors to improve their work. But misleading 1-star reviews from ignorant or impatient users can easily drag down the ratings of even the best tool. If you can't figure THIS addon out, you should probably deinstall the computer and install a plain TV.
