Instructions Neglected To Mention This. Rated 4 out of 5 stars

Well, I added it and it did nothing, So, I happened to right click the mouse and noticed the View selection. I clicked View and then it worked well.It opens another page with the image on it and you can zoom that new image...I gave it 4 stars because it is not documented very well and I wanted to hover over a pic and wheel i larger or smaller...Have Fun!

does not work Rated 1 out of 5 stars

Does not work at all. Scrolling just scrolls the web page, as usual, and this extension does not provide a way to set a toggle button for its function.
