Rated 4 out of 5 stars
It seems to work, but what is better than the existing extension or http://userscripts.org/scripts/show/73700 ? What is "use with RTM"? Would have been an improvement to turn it on and off on the fly without restarting, but not present...This review is for a previous version of the add-on (0.4).
Existing addon do not work with FF 3.6++.
http://userscripts.org/scripts/show/73700 - dunno, i've used to work with checkboxmate
RTM = remember the milk
i'll try force plugin to become enabled without restart in next version, got other feedback with suggestions so will update this addon in few weeks.
