Love FoxClocks; one of my essential addons. I hope the developer is able to get at least basic functionality working with the ability to choose and order clocks on a toobar at the bottom.

Shame on FireFox for expressing such a poor API that basic essential addons such as FoxClock, FlagFox, Classic Theme Restorer, Download Status Bar, and Favicon Restorer can't work. They'd fail my computer science classes!

Edit: I've switched to Waterfox, and it works perfectly!
