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??
