FYI: Intructions Did Not Come Up in Firefox 11.0 Rated 5 out of 5 stars
Works great, but took a bit figuring it out, because the "Instructions" do not show up in FireFox (11.0).
The instructions show up in Internet Explorer. But I had to copy the link from FireFox to IE. Once there I saw that the right-click menu exposes Auto Refresh. Until I could read that, I was searching the Tools, etc, menus at the top.
Just FYI. It would be great to immediately see within the instructions that you right-click in the current tab to activate it.
The tool itself is worthy of 5 stars. Please iron that small kink out of the instructions, and you'll have a perfect product.
