ONE thing lacking Rated 4 out of 5 stars

I LOVE and depend on ColorfulTabs, BUT - I keep LOSING my tab colors with new versions of Thunderbird or Earlybird! I gave up on Earlybird, thinking it was primarily at fault and then ran into the same problem with the latest update of Thunderbird 54.0b1

So the ONE think I would like to see is "save/restore configuration"

One other issue is that the "additional colors" do NOT appear to apply AS they are displayed. Is Thunderbird somehow not amenable to the expanded color attributes??

This review is for a previous version of the add-on (31.1.6).
