This is great. I noticed that in eBay it worked on the text but not the images next to the text in a search listing. Still 5 stars though I've been looking for something like this forever and I am sure you will work out all the bugs over time.
It's not one of the high tier extensions, but it fulfills what its purpose calls for and does it well.
I hope to see Firefox 3 support soon. So far the core functionalities works for Firefox 3, but the toolbar icon lost its ability to switch between its 2 icons to indicate the 2 states of this extension.
