Fantastic. Period. Been using various renditions of Speed Dial for many years now. This one is by far the best. Practically automatic. Ridiculously easy to set up. Anyone giving this a bad review has got personal issues.

I've found only one issue with it. The options button on the native FF Addons page doesn't open options. It opens the description page for the addon, but that isn't really an issue because there is more than one way to open the options from within the app.

Well done!
