Lost Custom Domain Colours Rated 5 out of 5 stars

In previous versions there were options to customise colours to a particular URL. This seems to have disappeared in 3.1. Or, at least, if you set a colour for an URL, it resets to random after restart.
Please reinstall this feature as it was very useful to remember colours for particular sites, just look up and see Camen Purple and it's Gentoo, etc.

This review is for a previous version of the add-on (3.1).
