Doesn't work Rated 5 out of 5 stars

It was just the add-on I was searching but unfortunatelly it doesn't work in FF 8.0, no icon is available and no highlights are shown :-(
Is it possible to fix this problem?
Thanks a lot

I don't understand the problem

My extension is compatible with version 8.0. There is no icon at all for my extension. You'll have to open the context menu (right-click in the web page) to select "highlight" or "unhighlight".
