Useless Rated 1 out of 5 stars
Tested on Firefox release channel 49.0.1 (Sept.26.2016)
The add-on installed without require restart,
but the no icons are shown, no settings are shown,
even customize panel has no icons for this.
Literally useless due to abandon of development from 2013.
Pointless Rated 2 out of 5 stars
Just basically gives you the equivalent of a web page with a giant clock in it. As if we needed an entire extension just to get that.This review is for a previous version of the add-on (0.1.1-signed.1-signed).
